ST25DV04K, ST25DV16K and ST25DV64K offer two interfaces. The first one is an I2C serial link and can be operated from a DC power supply. The second one is a RF link activated when ST25DV04K, ST25DV16K or ST25DV64K act as a contactless memory powered by the received carrier electromagnetic wave. In I2C mode, the ST25DV04K, ST25DV16K and ST25DV64K user memory contains up to 512 bytes, 2048 bytes and 8192 bytes, which could be split in 4 flexible and protectable areas. In RF mode, following ISO/IEC 15693 or NFC forum type 5 recommendations, ST25DV04K, ST25DV16K and ST25DV64K user memory contains respectively up to 128 blocks, 512 blocks and 2048 blocks of 4 bytes which could be split in 4 flexible and protectable areas. ST25DV04K, ST25DV16K and ST25DV64K offer a fast transfer mode between the RF and contact worlds, thanks to a 256 bytes volatile buffer (also called Mailbox). In addition, the GPO pin of the ST25DV04K, ST25DV16K and ST25DV64K provide data informing the contact world about incoming events, like RF field detection, RF activity in progress or mailbox message availability. An energy harvesting feature is also proposed when external conditions make it possible. Herein after all concerned devices (ST25DV04K, ST25DV16K and ST25DV64K) are mentioned as ST25DVxxx. 1.1 ST25DVxxx block diagram Figure 1.

In applications where this signal is used by slave devices to synchronize the bus to a slower clock, the bus master must have an open drain output, and a pull-up resistor must be connected from Serial Clock (SCL) to VCC. See Section 9.2 I2C DC and AC parameters to know how to calculate the value of this pull-up resistor 2.1.2 Serial data (SDA) This bidirectional signal is used to transfer data in or out of the ST25DVxxx. It is an open drain output that may be wire-OR’ed with other open drain or open collector signals on the bus. A pull-up resistor must be connected from Serial Data (SDA) to VCC. (Figure 76. I2C Fast mode (fC = 1 MHz): maximum Rbus value versus bus parasitic capacitance (Cbus) indicates how the value of the pull-up resistor can be calculated). 2.2 2.2.1 Power control (VCC, LPD,VSS) Supply voltage (VCC) This pin can be connected to an external DC supply voltage. Note: 2.2.2 An internal voltage regulator allows the external voltage applied on VCC to supply the ST25DVxxx, while preventing the internal power supply (rectified RF waveforms) to output a DC voltage on the VCC pin. Low Power Down (LPD) This input signal is used to control an internal 1.8 V regulator delivering ST25DVxxx internal supply. When LPD is high, this regulator is shut off and its consumption is reduced below 1µA. This regulator has a turn on time in range of 100us, to be added to the boot duration, before the device becomes fully operational. The impedance on LDP pin when set high doesn't exceed 5kΩ. This feature is only available on the 10-ball and 12-pin ST25DVxxx package. The LPD pin is internally pulleddown. 2.2.3 Ground (VSS) VSS is the reference for the VCC and VDCG supply voltages and V_EH analog output voltage. DS10925 - Rev 9 page 6/200 ST25DV04K ST25DV16K ST25DV64K RF link (AC0 AC1) 2.3 2.3.1 RF link (AC0 AC1) Antenna coil (AC0, AC1) These inputs are used to connect the ST25DVxxx device to an external coil exclusively. It is advised not to connect any other DC or AC path to AC0 or AC1. When correctly tuned, the coil is used to power and access the device using the ISO/IEC 15693 and ISO 18000-3 mode 1 protocols. 2.4 Process control (VDCG, GPO) 2.4.1 Driver Supply voltage (VDCG) This pin, available only with ST25DVxx-JF version, can be connected to an external DC supply voltage. It only supplies the GPO driver block. ST25DVxxx cannot be powered by VDCG. If VDCG is left floating, no information will be available on GPO pin. 2.4.2 General purpose output (GPO) The ST25DVxxx features a configurable output GPO pin used to provide RF activity information to an external device. ST25DVxx-IE offers a GPO open drain. This GPO pin must be connected to an external pull-up resistor (> 4.7 KΩ) to operate. The interrupt consists in pulling the state to a low level or outputting a low-level pulse on GPO pin. ST25DVxx-JF offers a GPO CMOS output, which requires to connect VDCG pin to an external power supply. The interrupt consists in setting the state to a high level or outputting a positive pulse on the GPO pin. GPO pin is a configurable output signal, and can mix several Interruption modes. By default, the GPO register sets the interruption mode as a RF Field Change detector. It is able to raise various events like RF Activity, Memory Write completion, or fast transfer actions. It can authorize the RF side to directly drive GPO pin using the Manage GPO command to set the output state or emit a single pulse (for example, to wake up an application.). See Section 5.2 GPO for details. 2.5 Energy harvesting analog output (V_EH) This analog output pin is used to deliver the analog voltage V_EH available when the Energy harvesting mode is enabled and if the RF field strength is sufficient. When the Energy harvesting mode is disabled or the RF field strength is not sufficient, V_EH pin is in High-Z state (See Section 5.3 Energy Harvesting (EH) for details). Energy harvesting voltage output is not regulated.

I2C operating conditions). To maintain a stable DC supply voltage, it is recommended to decouple the VCC line with a suitable capacitor (usually of the order of 10 nF and 100 nF) close to the VCC/VSS package pins. This voltage must remain stable and valid until the end of the transmission of the instruction and, for a Write instruction, until the completion of the internal I²C write cycle (tW). Instructions are not taken into account until completion of ST25DVxxx's boot sequence (see Figure 5. ST25DVxxx power-up sequence (No RF field, LPD pin tied to VSS or package without LPD pin) ). Figure 5. ST25DVxxx power-up sequence (No RF field, LPD pin tied to VSS or package without LPD pin) I2C interface ready Vcc Pin Power-Up by Vcc (No Vcc; VDCG) Vint_supply None Access Allowed RF or I2C I2C Start I2C Stop RF Access not allowed tboot* 2 IC * When RF Field is present before VCC set up boot is performed after RF field rising . * If LPD pin follow VCC before to goes low , tboot will start only when LPD reach the low level Power-up conditions When the power supply is turned on, VCC rises from VSS to VCC. The VCC rise time must not vary faster than 1V/µs. Device reset in I²C mode In order to prevent inadvertent write operations during power-up, a power-on reset (POR) circuit is included. At power-up (continuous rise of VCC), the ST25DVxxx does not respond to any I²C instruction until VCC has reached the power-on reset threshold voltage (this threshold is lower than the minimum VCC operating voltage defined in Table 243. I2C operating conditions). When VCC passes over the POR threshold, the device is reset and enters the Standby power mode. However, the device must not be accessed until VCC has reached a valid and stable VCC voltage within the specified [VCC(min), VCC(max)] range and t_boot time necessary to ST25DVxxx set-up has passed. In the version supporting LPD pin, the boot will take place only when LPD goes low. In a similar way, during power-down (continuous decrease in VCC), as soon as VCC drops below the power-on reset threshold voltage, the device stops responding to any instruction sent to it, and I2C address counter is reset. DS10925 - Rev 9 page 8/200 ST25DV04K ST25DV16K ST25DV64K Contactless interface Power-down mode During power-down (continuous decay of VCC), the device must be in Standby power mode (mode reached after decoding a Stop condition, assuming that there is no internal write cycle in progress). 3.2 Contactless interface Device set in RF mode To ensure a proper boot of the RF circuitry, the RF field must be turned ON without any modulation for a minimum period of time tRF_ON. Before this time, ST25DVxxx will ignore all received RF commands. (See Figure 6. ST25DVxxx RF power-up sequence (No DC supply)). Device reset in RF mode To ensure a proper reset of the RF circuitry, the RF field must be turned off (100% modulation) for a minimum tRF_OFF period of time. The RF access can be temporarily or indefinitely disabled by setting the appropriate value in the RF disable register. Figure 6.

Each area can be individually read and/or - write-protected with one out of three specific 64-bit password. The ST25DVxxx dynamic registers are accessible by RF or I2C host and provide dynamic activity status or allow temporary activation or deactivation of some ST25DVxxx features. The ST25DVxxx also provides a 256 byte fast transfer mode buffer, acting as a mailbox between RF and I2C interface, allowing fast data transfer between contact and contactless worlds. Finally, the ST25DVxxx system configuration area contains static registers to configure all ST25DVxxx features, which can be tuned by user. Its access is protected by a 64 bit configuration password. This system configuration area also includes read only device information such as IC reference, memory size or IC revision, as well as a 64-bit block that is used to store the 64-bit unique identifier (UID), and the AFI (default 00h) and DSFID (default 00h) registers. The UID is compliant with the ISO 15693 description, and its value is used during the anticollision sequence (Inventory). The UID value is written by ST on the production line. The AFI register stores the application family identifier. The DSFID register stores the data storage family identifier used in the anticollision algorithm. The system configuration area includes five additional 64-bit blocks that store an I2C password plus three RF user area access passwords and a RF configuration password.

From RF interface, user memory is addressed as Blocks of 4 bytes, starting at address 0. RF extended read and write commands can be used to address all ST25DVxxx memory blocks. Other read and write commands can only address up to block FFh. From I2C interface, user memory is addressed as Bytes, starting at address 0. Device select must be set with E2=0. User memory can be read in continuity. Unlike the RF interface, there is no roll-over when the requested address reaches the end of the memory capacity.

RF and I2C read and write commands are legal only within a same zone: • In RF, a multiple read or a multiple write command is not executed and returns the error code 0Fh if addresses cross the area borders. • In I2C, a read data always return FFh after crossing an area border. A write command is not acknowledged and not executed if the command crosses the area border. Each user memory area is defined by its ending block address ENDAi. The starting block address is defined by the end of the preceding area. There are three ENDAi registers in the configuration system memory, used to define the end block addresses of Area 1, Area 2 and Area 3. The end of Area 4 is always the last block of memory and is not configurable. Figure 8. ST25DVxxx user memory areas ST25DV user memory Block/Byte 0000h Areas limit registers Area1 (8 Blocks/32 Bytes minimum) ENDA1 Area2 ENDA2 Area3 ENDA3 Area4 Last Block/Byte of user memory On factory delivery all ENDAi are set to maximum value, only Area1 exists and includes the full user memory. A granularity of 8 Blocks (32 Bytes) is offered to code area ending points. An area’s end limit is coded as followed in ENDAi registers: • Last RF block address of area = 8 x ENDAi + 7 => ENDAi = int(Last Areai RF block address / 8) • Last I2C byte address of area = 32 * ENDAi + 31 => ENDAi = int(Last Areai I2C byte address / 32) • As a consequence, ENDA1 = 0 minimum size of Area 1 is 8 blocks (32 Bytes).

Area size programming RF user must first open the RF configuration security session to write ENDAi registers. I2C host must first open I2C security session to write ENDAi registers. When programming an ENDAi register, the following rule must be respected: • ENDAi-1 < ENDAi ≤ ENDAi+1 = End of memory. This means that prior to programming any ENDAi register, its successor (ENDAi+1) must first be programmed to the last Block/Byte of memory: • Successful ENDA3 programming condition: ENDA2 < ENDA3 ≤ End of user memory • Successful ENDA2 programming condition: ENDA1 < ENDA2 ≤ ENDA3 = End of user memory • Successful ENDA1 programming condition: ENDA1 ≤ ENDA2 = ENDA 3 = End of user memory If this rule is not respected, an error 0Fh is returned in RF, NoAck is returned in I2C, and programming is not done. In order to respect this rule, the following procedure is recommended when programming Areas size (even for changing only one Area size): DS10925 - Rev 9 page 14/200 ST25DV04K ST25DV16K ST25DV64K User memory 1. Ends of Areas 3 and 2 must first be set to the end of memory while respecting the following order: a. If ENDA3 ≠ end of user memory, then set ENDA3 = end of memory; else, do not write ENDA3. b. If ENDA2 ≠ end of user memory, then set ENDA2 = end of memory; else, do not write ENDA2. 2. Then, desired area limits can be set respecting the following order: a. Set new ENDA1 value. b. Set new ENDA2 value, with ENDA2 > ENDA1 c. Set new ENDA3 value, with ENDA3 > ENDA2 Example of successive user memory area setting (for a ST25DV64K-xx): 1. Initial state, 2 Areas are defined: a. ENDA1 = 10h (Last block of Area 1: (10h x 8) + 7 = 0087h) b. ENDA2 = FFh (Last block of Area 2: (FFh x 8) + 7 = 07FFh) c. ENDA3 = FFh (No Area 3) ◦ Area 1 from Block 0000h to 0087h (136 Blocks) ◦ Area 2 from Block 0088h to 07FFh (1912 Blocks) ◦ There is no Area 3 ◦ There is no Area 4 2. Split of user memory in four areas: a. ENDA3 is not updated as it is already set to end of memory b. ENDA2 is not updated as it is already set to end of memory c. Set ENDA1 = 3Fh (Last block of Area 1: (3Fh x 8) + 7 = 01FFh) d. Set ENDA2 = 5Fh (Last block of Area 1: (5Fh x 8) + 7 = 02FFh) e.

Those registers are set during device configuration (i.e.: area extension), or by the application (i.e.: area protection). Static registers content is read during the boot sequence and define basic ST25DVxxx behavior. In RF, the static registers located in the system configuration area can be accessed via dedicated Read Configuration and Write Configuration commands, with a pointer acting as the register address. The RF configuration security session must first be open, by presenting a valid RF configuration password, to grant write access to system configuration registers. The system configuration area write access by RF can also be deactivated by I2C host. In I2C static registers located in the system configuration area can be accessed with I2C read and write commands with device select E2=1. Readable system areas could be read in continuity. I2C security session must first be open, by presenting a valid I2C password, to grant write access to system configuration registers. Table 11.

Dynamic registers are volatile and not restored to their previous values after POR. Some static registers have an image in dynamic registers: dynamic register value is initialized with the static register value and may be updated by the application to modify the device behavior temporarily (i.e.: set reset of Energy Harvesting). When a valid change occurs in a static register, in RF or I2C, the corresponding dynamic register is automatically updated. Other, dynamic registers, automatically updated, contain indication on ST25DV activity. (i.e.: IT_STS_Dyn gives the interruption’s status or MB_CTRL_Dyn gives the fast transfer mode mailbox control). In RF, dynamic registers can be accessed via dedicated (Fast) Read Dynamic Configuration and (Fast) Write Dynamic Configuration commands, with a pointer acting as the register address. No password is needed to access dynamic registers. In I2C, dynamic registers can be accessed with I2C read and write commands with device select E2=0. Dynamic registers can be read in continuity. Dynamic registers and fast transfer mode mailbox can be read in continuity, but not written in continuity. No password is needed to access dynamic registers. Table 12.

This mailbox contains up to 256 Bytes of data which are filled from the first byte. Fast transfer mode mailbox is accessed in bytes from both RF and I2C. In RF, mailbox is read via a dedicated (Fast) Read Message command. Read can start from any address value inside the mailbox, between 00h and FFh. Writing in the mailbox is done via the (Fast) Write Message command in one shot, always starting at mailbox address 00h. No password is needed to access mailbox from RF, but fast transfer mode must be enabled. In I2C, mailbox read can start from any address value between 2008h and 2107h. Write mailbox MUST start from address 2008h to a max of 2107h. No password is needed to access mailbox from I2C, but fast transfer mode must be enabled. Table 13.

This mailbox dynamic buffer of 256 byte can be filled or emptied via either RF or I2C. • A GPO pin, which indicates incoming event to the contact side, like RF Field changes, RF activity in progress, RF writing completion or Mailbox message availability. • An Energy Harvesting element to deliver µW of power when external conditions make it possible. • RF management, which allows ST25DVxxx to ignore RF requests. All these features can be programmed by setting static and/or dynamic registers of the ST25DVxxx. ST25DVxxx can be partially customized using configuration registers located in the E2 system area. These registers are: • dedicated to Data Memory organization and protection ENDAi, I2CSS, RFAiSS, LOCK_CCFILE. • • • • dedicated to fast transfer mode MB_WDG, MB_MODE dedicated to observation, GPO, IT_TIME dedicated to RF , RF_MNGT, EH_MODE dedicated the device’s structure LOCK_CFG A set of additional registers allows to identify and customize the product (DSFID, AFI, IC_REF, etc.). In I²C, Read accesses to the static configuration register is always allowed, except for passwords. For dedicated registers, write access is granted after prior successful presentation of the I2C password. Configuration register are located from @00h to 0Fh in the system area (device code 111) In RF Dedicated commands Read Configuration and Write Configuration must be used to access the static configuration registers. Update is only possible when the access right was granted by presenting the RF configuration password (RF_PWD_0), and if the system configuration was not previously locked by the I2C host (LOCK_CFG=1), which acts as security master. After any valid write access to the static configuration registers, the new configuration is immediately applied. Some of the static registers have a dynamic image (notice _Dyn) preset with the static register value: GPO_CTRL_Dyn, EH_CTRL_Dyn, RF_MNGT_Dyn and MB_CTRL_Dyn. When it exists, ST25DVxxx uses the dynamic configuration register to manage its processes. A dynamic configuration register updated by the application will recover its default static value after a Power On Reset (POR). Other dynamic registers are dedicated to process monitoring: • I2C_SSO_Dyn is dedicated to data memory protection • MB_LEN_Dyn, MB_CTRL_Dyn are dedicated to fast transfer mode • IT_STS_Dyn is dedicated to interrupt In I2C, read and write of the Dynamic registers is done using usual I2C read & write command at dedicated address. (E2 =0 in device select). In RF read or write accesses to the Dynamic registers are associated to the dedicated commands, Read Dynamic Configuration, Write Dynamic Configuration and Read Message Length.

Each interface can send a message containing up to 256 bytes of data to the other interface through that mailbox. To send data from RF reader to I2C host, fast transfer mode must be enabled, the mailbox must be free, VCC power must be present, and the RF user must first writes the message containing data in the mailbox. I2C host is then informed (by interruption on GPO output or polling on MB_CTRL_Dyn register) that a message from RF is present in the mailbox. Once the complete message has been read by I2C, mailbox is considered free again and is available for receiving a new message (data is not cleared). The RF user is informed that the message has been read by the I2C host by polling on MB_CTRL_Dyn register. Figure 9.

Once the complete message has been read by RF user, mailbox is considered free again and is available for receiving a new message (data is not cleared).

No precedence rule is applied: the first request is served first. Adding a message is only possible when fast transfer mode is enabled (MB_EN=1) and mailbox is free (HOST_PUT_MSG and RF_PUT_MSG cleared, which is the case after POR or after complete reading of I2C message by RF, and complete reading of RF message by I2C). A watchdog limits the message availability in time: when a time-out occurs, the mailbox is considered free, and the HOST_MISS_MSG or RF_MISS_MSG bits is set into MB_CTRL_Dyn register. The data contained in the mailbox is not cleared after a read or after the watchdog has been triggered: message data is still available for read and until fast transfer mode is disabled. HOST_CURRENT_MSG and RF_CURRENT_MSG bits are indicating the source of the current data. The message is stored in a buffer (256 Bytes), and the write operation is done immediately. . Caution: The data written in user or system memory (EEPROM), either from I2C or from RF, transits via the 256-Bytes fast transfer mode's buffer. Consequently fast transfer mode must be deactivated (MB_EN=0) before starting any write operation in user or system memory, otherwise command will be NotACK for I2C or get an answer 0Fh for RF and programming is not done. I2C access to mailbox The access by I2C can be done by dedicated address mapping to mailbox (2008h to 2107h) with device identifier E2 = 0. I2C reading operation does not support rollover. Therefore data out is set to FFh when the counter reaches the message end. The RF_PUT_MSG is cleared after reaching the STOP consecutive to reading the last message byte, and the mailbox is considered free (but the message is not cleared and it is still present in the mailbox). A I2C reading operation will never clear HOST_PUT_MSG, and the message remains available for RF. An I2C read can start at any address inside the mailbox (between address 2008h and 2107h). A I2C write operation must start from the first mailbox location, at address 2008h. After reaching the Mailbox border at address 2107h all bytes are NACK and the command is not executed (rollover feature not supported). At the end of a successful I2C message write, the message length is automatically set into MB_LEN_Dyn register, and HOST_PUT_MSG bit is set into MB_CTRL_Dyn register, and the write access to the mailbox is not possible until the mailbox has been released again. MB_LEN_Dyn contains the size of the message in byte, minus 1. DS10925 - Rev 9 page 25/200 ST25DV04K ST25DV16K ST25DV64K Fast transfer mode (FTM) RF access to mailbox The RF Control & Access to mailbox is possible using dedicated custom commands: • Read Dynamic Configuration and Fast Read Dynamic Configuration to check availability of mailbox. • Write Dynamic Configuration and Fast Write Dynamic configuration to enable or disable fast transfer mode. • Read Message Length and Fast Read Message Length to get the length of the contained message, • Read Message and Fast Read Message to download the content of the mailbox, • Write Message and Fast Write Message to put a new message in mailbox. (New length is automatically updated after completion of a successful Write Message or Fast Write Message command). HOST_PUT_MSG is cleared following a valid reading of the last message byte, and mailbox is considered free (but message is not cleared and is still present in the mailbox). A RF read can start at any address of inside the message, but return an error 0Fh if trying to read after the last byte of the message. A RF reading operation will never clear RF_PUT_MSG , the message will remain available for I2C. At the end of a successful RF message write, the message length is automatically set in MB_LEN_Dyn register, and RF_PUT_MSG bit is set in MB_CTRL_Dyn register. and write access to the mailbox is not possible until mailbox has been freed again. The presence of a DC supply is mandatory to get RF access to the mailbox. VCC_ON can be checked reading the dynamic register EH_CTRL_Dyn.

When the Energy harvesting mode is disabled or the RF field strength is not sufficient, the energy harvesting analog voltage output V_EH is in High-Z state. EH_MODE Static Register is used to define the Energy Harvesting default strategy after boot. At boot EH_EN (in EH_CTRL_Dyn register) is set depending EH_MODE value as shown in table below: Table 38. Energy harvesting at power-up EH_MODE EH_EN (at boot) 0 1 1 0 Energy harvesting at power-up EH enabled after boot (when possible) EH disabled initially, EH delivered on demand (when possible) Writing 0 in EH_MODE at any time after boot will automatically set EH_EN bit to 1, and thus activate energy harvesting. Writing 1 in EH_MODE at any time after boot will not modify EH_EN bit (until next reboot) and thus will not modify energy harvesting current state. EH_CTRL_Dyn allows to activate or deactivate on the fly the Energy harvesting (EH_EN) and bring information on actual state of EH and state of power supplies : • EH_ON set reflects the EH_EN bit value • FIELD_ON is set in presence of a RF field • VCC_ON is set when Host power supply is on, and low power-down mode is not forced. During boot, EH is not delivered to avoid alteration in device configuration. Caution: DS10925 - Rev 9 Communication is not guaranteed during EH delivery. Refer to the application note AN4913 (Energy harvesting delivery impact on ST25DVxxx behaviour during RF communication). Energy harvesting can be set even if ST25DVxxx is in RF disabled or RF Sleep mode, or in Low power mode. In all these cases, ST25DVxxx will deliver power on V_EH pin if RF field is present.

At boot time, and each time RF_MNGT register it is updated, content of RF_MNGT_Dyn register is copied from RF_MNGT register. The content of RF_MNGT_Dyn register is used during application to set ST25DVxxx behavior. Content of this dynamic register RF_MNGT_Dyn can be updated on the fly, to temporarily modify the behavior of ST25DVxxx without affecting the static value of RF_MNGT which will be recovered at next POR. RF_MNGT register is composed of two bits (see Table 42. RF_MNGT_Dyn): RF_DISABLE and RF_SLEEP For a normal usage of RF interface, bits RF_SLEEP and RF_DISABLE must be set to 0. For RF are offered three modes: • RF sleep mode: – When RF_SLEEP is set to 1, all RF communications are disabled, RF interface doesn’t interpret commands, but minimizes consumption of RF interface. • RF disable mode: – When RF_SLEEP is set to 0 and RF_DISABLE is set to 1, RF commands are interpreted but not executed. In case of a valid command, ST25DVxxx will respond after t1 with the error code 0Fh. The Inventory command is not answered. • RF normal mode: – In normal usage, RF_SLEEP and RF_DISABLE are set to 0, ST25DVxxx will process the request and respond accordingly when I2C is not accessing ST25DVxxx. If I2C is busy, ST25DV will respond to RF request with the error code 0Fh.

RF user and I2C host can access those protected data by opening security sessions with the help of passwords. Access rights is more restricted when security sessions are closed, and less restricted when security sessions are open. Dynamic registers and fast transfer mode mailbox are not protected by any security session. There is three type of security sessions, as shown in Table 69. Security session type: DS10925 - Rev 9 page 55/200 ST25DV04K ST25DV16K ST25DV64K Data Protection Table 69.

Password number must be the same as the one selected for protection. 2. Write access to the password number corresponding to the password number presented. All passwords are 64-bits long, and default factory passwords value is 0000000000000000h. The ST25DVxxx passwords management is organized around RF and I2C dedicated set of commands to access the dedicated registers in system configuration area where password values are stored. The dedicated password commands in RF mode are: • Write Password command (code B1h): see Section 7.6.35 Write Password. • Present Password command (code B3h): see Section 7.6.36 Present Password. RF user possible actions for security sessions are: • Open RF user security session: Present Password command, with password number 1, 2 or 3 and the valid corresponding password • Write RF password: Present Password command, with password number (0, 1, 2 or 3) and the current valid corresponding password. Then Write Password command, with same password number (0, 1, 2 or 3) and the new corresponding password. • Close RF user security session: Present Password command, with a different password number than the one used to open session or any wrong password. Or remove tag from RF field (POR). Presenting a password with an invalid password number doesn't close the session. • Open RF configuration security session: Present Password command, with password number 0 and the valid password 0. • Close RF configuration security session: Present Password command, with a password number different than 0, or password number 0 and wrong password 0. Or remove tag from RF field (POR). Presenting a password with an invalid password number doesn't close the session. Opening any new RF security session (user or configuration) automatically close the previously open one (even if it fails). There is no interaction between I2C and RF security sessions. Both are independent, and can run in parallel. Caution: DS10925 - Rev 9 If ST25DVxxx is powered through VCC, removing VCC during a RF command can abort the command. As a consequence, before writing a new password, RF user should check if VCC is ON, by reading EH_CTRL_Dyn register bit 3 (VCC_ON), and eventually ask host to maintain or to shut down VCC, before issuing the Write Password command in order to avoid password corruption. To make the application more robust, it is recommended to use addressed or selected mode during write password operations to get the traceability of which tags/UID have been programmed. page 56/200 ST25DV04K ST25DV16K ST25DV64K Data Protection Figure 22.

Presenting a password with an invalid password number doesn't close the session. The dedicated password commands in I2C mode are: • I2C Write Password command: see Section 6.6.2 I2C write password command description. • I2C Present Password command: see Section 6.6.1 I2C present password command description. I2C host possible actions for security sessions are: • Open I 2 C security session: I2C Present Password command with valid I2C password. • Write I 2 C password: I2C Present Password command with valid I2C password. Then I2C Write Password command with new I2C password. • Close I 2 C security session: I2C Present Password command with wrong I2C password. Or remove tag VCC power supply (POR). • Check if I 2 C security session is open: I2C host can read the current status (open or closed) of I2C security session by reading the I2C_SSO_Dyn register. There is no interaction between I2C and RF security sessions. Both are independent and can run in parallel. DS10925 - Rev 9 page 57/200 ST25DV04K ST25DV16K ST25DV64K Data Protection Figure 23.

Each area can be individually protected in read and/or write access from RF and I2C. Area 1 is always readable (from RF and I2C). Furthermore, RF blocks 0 and 1 (I2C bytes 0000h to 0007h) can be independently write locked. User memory protection from RF access In RF mode, each memory area of the ST25DVxxx can be individually protected by one out of three available passwords (RF password 1, 2 or 3), and each area can also have individual Read/Write access conditions. For each area, an RFAiSS register is used to: • • Select the RF password that unlock the RF user security session for this area Select the protection against read and write operations for this area (See Table 44. RFA1SS, Table 46. RFA2SS, Table 48. RFA3SS, and Table 50. RFA4SS for details about available read and write protections). Note: DS10925 - Rev 9 Setting 00b in PWD_CTRL_Ai field means that RF user security session cannot be open by any password for the corresponding area. When updating RFAiSS registers, the new protection value is effective immediately after the register write completion. page 58/200 ST25DV04K ST25DV16K ST25DV64K Data Protection • Rf blocks 0 and 1 are exceptions to this protection mechanism: – RF blocks 0 and 1 can be individually write locked by issuing a (Ext) Lock Single Block RF command. Once locked, they cannot be unlock through RF. LOCK_CCFILE register is automatically updated when using (Ext) Lock Single Block command. – A RF user needs no password to lock blocks 0 and/or 1. – Locking blocks 0 and/or 1 is possible even if the configuration is locked (LOCK_CFG=1). – Locking blocks 0 and/or 1 is possible even if the area is write locked. – Unlocking area1 (through RFA1SS register) does not unlock blocks 0 and 1 if they have been locked though (Ext) Lock Block command. – Note: Once locked, the RF user cannot unlock blocks 0 and/or 1 (can be done by I2C host). When areas size are modified (ENDAi registers), RFAiSS registers are not modified. User memory protection from I2C access In I2C mode, each area can also have individual Read/Write access conditions, but only one I2C password is used to unlock I2C security session for all areas. The I2CSS register is used to set protection against read and write operation for each area (see Table 52. I2CSS for details about available read and write protections). When updating I2CSS registers, the new protection value is effective immediately after the register write completion. I2C user memory Bytes 0000h to 0003h (RF Block 0) and 0004h to 0007h (RF Block 1) can be individually locked and unlocked by writing in the LOCK_CCFILE register (by group of 4 Bytes), independently of Area 1 protection. Unlocking Area 1 (through I2CSS register) does not unlock those bytes if they have been locked though the LOCK_CCFILE register. Note: When areas size are modified (ENDAi registers), I2CSS register is not modified. Retrieve the security status of a user memory block or byte RF user can read a block security status by issuing following RF commands: • (Ext) Get Multiple Blocks Security Status command. • (Ext) (Fast) Read Single Block with option flag set to 1. • (Ext) (Fast) Read Multiple Blocks with option flag set to 1. ST25DV will respond with a Block security status containing a Lock_bit flag as specified in ISO 15693 standard. This lock_bit flag is set to one if block is locked against write. Lock_bit flag value may vary if corresponding RF user security session is open or closed. I2C host can retrieve a block security status by reading the I2CSS register to get security status of the corresponding area and by reading the I2C_SSO_Dyn register to know if I2C security session is open or closed. For blocks 0 and 1 (Bytes 0000h to 0007h in I2C user memory), lock status can also be read in the LOCK_CCFILE register. 5.6.4 System memory protection By default, system memory (static registers) is write protected, both in RF and I2C. I2C host must open the I2C security session (by presenting a valid I2C password) to enable write access to system configuration static registers. I2C host doesn’t have read or write access to RF passwords. By default, I2C host can read all system configuration static registers (except RF passwords) In RF, to enable write access to system configuration static registers, RF user must open the RF configuration security session (by presenting a valid RF password 0) and system configuration must not be locked (LOCK_CFG=00h). RF doesn’t have read or write access to I2C password. By default, RF user can read all system configuration static registers, except all passwords, LOCK_CCFILE, LOCK_DSFID and LOCK_AFI. RF configuration lock: DS10925 - Rev 9 page 59/200 ST25DV04K ST25DV16K ST25DV64K Device Parameter Registers • • • RF write access to system configuration static registers can be locked by writing 01h in the LOCK_CFG register (by RF or I2C). RF user cannot unlock system configuration if LOCK_CFG=01h, even after opening RF configuration security session (only I2C host can unlock system configuration). When system configuration is locked (LOCK_CFG=01h), it is still possible to change RF passwords (0 to 3). Device identification registers: • AFI and DFSID registers can be independently locked by RF user, issuing respectively a Lock AFI and a Lock DSFID command. Lock is definitive: once locked, AFI and DSFID registers cannot be unlocked (either by RF or I2C). System configuration locking mechanism (LOCK_CFG=01h) does not lock AFI and DSFID registers. • Other device identification registers (MEM_SIZE, BLK_SIZE, IC_REF, UID, IC_REV) are read only registers for both RF and I2C. 5.7 Device Parameter Registers Table 70.

This is summarized in Figure 24. I2C bus protocol. Any device that sends data to the bus is defined as a transmitter, and any device that reads data is defined as a receiver. The device that controls the data transfer is known as the bus master, and the other as the slave device. A data transfer can only be initiated by the bus master, which also provides the serial clock for synchronization. The ST25DVxxx device is a slave in all communications. Figure 24. I2C bus protocol STOP Condition 6.1.1 Start condition Start is identified by a falling edge of serial data (SDA) while the serial clock (SCL) is stable in the high state. A Start condition must precede any data transfer command. The device continuously monitors (except during a write cycle) the SDA and the SCL for a Start condition, and does not respond unless one is given. DS10925 - Rev 9 page 64/200 ST25DV04K ST25DV16K ST25DV64K I2C timeout 6.1.2 Stop condition Stop is identified by a rising edge of serial data (SDA) while the serial clock (SCL) is stable and driven high. A Stop condition terminates communication between the device and the bus master. A Read command that is followed by NoAck can be followed by a Stop condition to force the device into the Standby mode. A Stop condition at the end of a Write command triggers the internal write cycle. 6.1.3 Acknowledge bit (ACK) The acknowledge bit is used to indicate a successful byte transfer. The bus transmitter, whether a bus master or a slave device, releases the serial data (SDA) after sending eight bits of data. During the 9th clock pulse period, the receiver pulls the SDA low to acknowledge the receipt of the eight data bits. 6.1.4 Data input During data input, the device samples serial data (SDA) on the rising edge of the serial clock (SCL). For correct device operation, the SDA must be stable during the rising edge of the SCL, and the SDA signal must change only when the SCL is driven low. 6.2 I2C timeout During the execution of an I²C operation, RF communications are not possible. To prevent RF communication freezing due to inadvertent indeterminate instructions sent to the I²C bus, the ST25DVxxx features a timeout mechanism that automatically resets the I²C logic block. 6.2.1 I2C timeout on Start condition I2C communication with the ST25DVxxx starts with a valid Start condition, followed by a device select code. If the delay between the Start condition and the following rising edge of the serial clock (SCL) that samples the most significant of the Device Select exceeds the tSTART_OUT time (see Table 248. I2C AC characteristics up to 85°C and Table 249. I2C AC characteristics up to 125°C), the I²C logic block is reset and further incoming data transfer is ignored until the next valid Start condition. Figure 25. I²C timeout on Start condition SCL SDA tSTART_OUT Start condition 6.2.2 I2C timeout on clock period During data transfer on the I²C bus, if the serial clock pulse width high (tCHCL) or serial clock pulse width low (tCLCH) exceeds the maximum value specified in Table 248. I2C AC characteristics up to 85°C and Table 249. I2C AC characteristics up to 125°C, the I²C logic block is reset and any further incoming data transfer is ignored until the next valid Start condition. DS10925 - Rev 9 page 65/200 ST25DV04K ST25DV16K ST25DV64K Device addressing 6.3 Device addressing To start a communication between the bus master and the slave device, the bus master must initiate a Start condition. Following this, the bus master sends the device select code, shown in Table 88. Device select code (on Serial Data (SDA), the most significant bit first). The device select code consists of a 4-bit device type identifier and a 3-bit Chip Enable “Address” (E2,1,1). To address the memory array, the 4-bit device type identifier is 1010b. Refer to Table 88. Device select code. The eighth bit is the Read/Write bit (RW). It is set to 1 for Read and to 0 for Write operations. Table 88. Device select code Device type identifier (1) b7 Device select code 1 b6 0 b5 Chip Enable address b4 1 0 b3 E2(2) b2 RW b1 1 b0 1 RW 1. The most significant bit, b7, is sent first. 2. E2 is not connected to any external pin. It is however used to address the ST25DVxxx as described in Section 4 Memory management. • E2 = 0, access to user memory, Dynamic registers or Mailbox. • E2 =1, access to system area. If a match occurs on the device select code, the corresponding device gives an acknowledgment on serial data (SDA) during the ninth bit time. If the device does not match the device select code, it deselects itself from the bus, and goes into Standby mode. Table 89. Operating modes Mode RW bit Current address read Random address read 6.4 1 Bytes Initial sequence 1 0 Start, device select, RW = 1 Start, device select, RW = 0, address 1 1 reStart, device select, RW = 1 Sequential read 1 ≥1 Similar to current or random address read Byte write 0 1 Start, device select, RW = 0 Sequential write 0 ≤ 256 byte Start, device select, RW = 0 I2C Write operations Following a Start condition, the bus master sends a device select code with the Read/Write bit (RW) reset to 0. The device acknowledges this, and waits for two address bytes. The device responds to each address byte with an acknowledge bit, and then waits for the data byte. Each data byte in the memory has a 16-bit (two-byte wide) address. The most significant byte (see Table 90. Address most significant byte) is sent first, followed by the least significant byte (see Table 91. Address least significant byte). Bits b15 to b0 form the address of the byte in memory. Table 90. Address most significant byte b15 b14 b13 b12 b11 b10 b9 b8 Table 91. Address least significant byte b7 DS10925 - Rev 9 b6 b5 b4 b3 b2 b1 b0 page 66/200 ST25DV04K ST25DV16K ST25DV64K I2C Write operations When the bus master generates a Stop condition immediately after the Ack bit (in the tenth-bit time slot), either at the end of a byte write or a sequential write, the internal write cycle is triggered. A Stop condition at any other time slot does not trigger the internal write cycle. After the Stop condition, the delay tW, and the successful completion of a Write operation, the device’s internal address counter is incremented automatically, to point to the next byte address after the last one that was modified. After an unsuccessful write operation, ST25DVxxx enters in I2C dead state: internal address counter is not incremented, and ST25DVxxx is waiting for a full new I2C instruction (address counter stops to be incremented after the first NoAck bit). During the internal write cycle, the serial data (SDA) signal is disabled and the device does not respond to any requests. Caution: 6.4.1 I2C Writing data in user or system memory (EEPROM), transit via the 256-Bytes fast transfer mode's buffer. Consequently fast transfer mode must be deactivated before starting any write operation in user or system memory, otherwise command will be NotACK, programming is not done and device goes in standby mode. I2C Byte write After the device select code and the address bytes, the bus master sends one data byte. If byte write is not inhibited, the device replies with Ack. If byte write is inhibited, the device replies with NoAck. The bus master terminates the transfer by generating a Stop condition (see Figure 26. Write mode sequences when write is not inhibited). For byte write in EEPROM (user memory or system configuration), internal programming starts after the Ack, for a duration of tW (as defined in Table 248. I2C AC characteristics up to 85°C and Table 249. I2C AC characteristics up to 125°C). For writes in fast transfer mode buffer or Dynamic registers, internal programming is done at the Ack. If byte write is inhibited, the device replies with NoAck. The bus master terminates the transfer by generating a Stop condition and byte location not is modified (see Figure 27. Write mode sequences when write is inhibited). Byte write is inhibited if byte complies with one of the following conditions: • Byte is in user memory and is write protected with LOCK_CCFILE register. 6.4.2 • • • Byte is in user memory and is write protected with I2CSS register, and I2C security session is closed. Byte is in user memory and fast transfer mode is activated. Byte is in system memory and is a Read Only register. • • • • • Byte is in system memory and I2C security session is closed. Byte is in fast transfer mode’s mailbox and is not the first Byte of mailbox. Byte is in fast transfer mode’s mailbox and mailbox is busy. Byte is in fast transfer mode’s mailbox and fast transfer mode is not activated. Byte is in dynamic registers area and is a Read Only register. I2C Sequential write The I2C sequential write allows up to 256 bytes to be written in one command, provided they are all located in the same user memory area or are all located in writable addresses. After each byte is transferred, the internal byte address counter is incremented. For each byte sent by the bus master: • If byte write is not inhibited, the device replies with Ack. • If byte write is inhibited, the device replies with NoAck. The transfer is terminated by the bus master generating a Stop condition: • For writes in EEPROM (user memory or system configuration), if all bytes have been Ack'ed, internal programming of all bytes starts after the last Ack, for a duration dependent on the number of bytes to write (see below). • For writes in fast transfer mode buffer or Dynamic registers, if all bytes have been Ack'ed, internal programming is done at the Ack. • If some bytes have been NotAck’ed, no internal programming is done (0 byte written). DS10925 - Rev 9 page 67/200 ST25DV04K ST25DV16K ST25DV64K I2C Write operations Byte write is inhibited if byte complies with conditions described in Section 6.4.1 I2C Byte write, in addition: • Byte is in user memory but does not belong to same area than previous received byte (area border crossing is forbidden). • 256 write occurrence have already been reached in the same sequential write. EEPROM memory (user memory and system configuration) is internally organized in pages of 4 bytes long. Data located in a same page all share the same most significant memory address bits b16-b2. I2C sequential write programming time in the EEPROM memory is dependent on this internal organization: total programming time is the I2C write time tW (as defined in Table 248. I2C AC characteristics up to 85°C and Table 249. I2C AC characteristics up to 125°C) multiplied by the number of internal EEPROM pages where the data must be programmed, including incomplete pages. For example, a 256 Bytes I2C sequential write, starting at address 0002h will write data over 65 pages. Total write time in this case is tW x 65. Figure 26.

The maximum I²C write time (tw) is shown in Table 248. I2C AC characteristics up to 85°C and Table 249. I2C AC characteristics up to 125°C, but the typical time is shorter. To make use of this, a polling sequence can be used by the bus master. The sequence, as shown in Figure 28, is: • Initial condition: a write cycle is in progress. • Step 1: the bus master issues a Start condition followed by a device select code (the first byte of the new instruction). • Step 2: if the device is busy with the internal write cycle, no Ack is returned and the bus master goes back to Step 1. If the device has terminated the internal write cycle, it responds with an Ack, indicating that the device is ready to receive the second part of the instruction (the first byte of this instruction having been sent during Step 1). Note: There is no need of polling when writing in dynamic registers or in mailbox, since programming time is null. Figure 28. Write cycle polling flowchart using ACK Write cycle in progress Start condition Device select with RW = 0 NO ACK returned YES First byte of instruction with RW = 0 already decoded by the device NO Next Operation is addressing the memory YES Send Address and Receive ACK Stop NO DS10925 - Rev 9 StartCondition YES Data for the Write operation Device select with RW = 1 Continue the Write operation Continue the Random Read operation page 69/200 ST25DV04K ST25DV16K ST25DV64K I2C read operations 6.5 I2C read operations Read operation in user memory is performed successfully only if: • Area to which the byte belongs is not read protected by I2CSS register. • Area to which the byte belongs is read protected by I2CSS register, but I2C security session is open. Read operations in system memory and dynamic registers are done independently of any protection mechanism, except I2C_PWD register which needs I2C security session to be open first. Read operation in fast transfer mode’s mailbox is performed successfully only if fast transfer mode is activated. If read is not successful, ST25DVxxx releases the bus and I2C host reads byte value FFh. After the successful completion of a read operation, the device’s internal address counter is incremented by one, to point to the next byte address. After an unsuccessful read operation, ST25DVxxx enters in I2C dead state: internal address counter is not incremented, and ST25DVxxx is waiting for a full new I2C instruction. 6.5.1 Random Address Read A dummy write is first performed to load the address into this address counter (as shown in Figure 29. Read mode sequences) but without sending a Stop condition. Then, the bus master sends another Start condition, and repeats the device select code, with the Read/Write bit (RW) set to 1. The device acknowledges this, and outputs the contents of the addressed byte. The bus master must not acknowledge the byte, and terminates the transfer with a Stop condition. 6.5.2 Current Address Read For the Current Address Read operation, following a Start condition, the bus master only sends a device select code with the Read/Write bit (RW) set to 1. The device acknowledges this, and outputs the byte addressed by the internal address counter. The counter is then incremented. The bus master terminates the transfer with a Stop condition, as shown in Figure 29. Read mode sequences, without acknowledging the byte. DS10925 - Rev 9 page 70/200 ST25DV04K ST25DV16K ST25DV64K I2C read operations Figure 29.

The bus master does acknowledge the data byte output, and sends additional clock pulses so that the device continues to output the next byte in sequence. To terminate the stream of bytes, the bus master must not acknowledge the last byte, and must generate a Stop condition, as shown in Figure 29. Read mode sequences. The output data comes from consecutive addresses, with the internal address counter automatically incremented after each byte output. Sequential read in user memory: • Sequential read cannot cross area borders. After reaching area border, device continues to output FFh • There is no roll over inside area or at the end of user memory (ST25DVxxx returns only FFh after last user memory byte address). Sequential read in system memory: • There is no roll over after reaching end of system memory (ST25DVxxx returns only FFh after last system memory byte address). • Sequential read in dynamic registers: • DS10925 - Rev 9 It is possible to read sequentially dynamic registers and fast transfer mode’s mailbox (contiguous I2C addresses). page 71/200 ST25DV04K ST25DV16K ST25DV64K I2C password management Sequential read in dynamic registers: • 6.5.4 There is no roll over at the end of the mailbox (ST25DVxxx returns only FFh after last system memory byte address). Acknowledge in Read mode For all Read commands, the device waits, after each byte read, for an acknowledgement during the ninth bit time. If the bus master does not drive serial data (SDA) low during this time, the device terminates the data transfer and switches to its Standby mode. 6.6 I2C password management The ST25DVxxx controls I2C security session using an I2C 64-bit password. This I2C password is managed with two I2C dedicated commands: I2C present password and I2C write password. 6.6.1 I2C present password command description The I2C present password command is used in I2C mode to present the password to the ST25DVxxx. This is used to open I2C security session or to allow I2C password modification (see Section 5.6 Data Protection for detailed explanation about password usage). Following a Start condition, the bus master sends a device select code with the Read/ Write bit (R W ) reset to 0 and the Chip Enable bit E2 at 1. The device acknowledges this, as shown in Figure 30. I2C Present Password Sequence, and waits for two I2C password address bytes, 09h and 00h. The device responds to each address byte with an acknowledge bit, and then waits for the eight password data bytes, the validation code, 09h, and a resend of the eight password data bytes. The most significant byte of the password is sent first, followed by the least significant bytes. It is necessary to send the 64-bit password twice to prevent any data corruption during the sequence. If the two 64-bit passwords sent are not exactly the same, the ST25DVxxx does not start the internal comparison. When the bus master generates a Stop condition immediately after the Ack bit (during the tenth bit time slot). The ST25DVxxx compares the 64 received data bits with the 64 bits of the stored I2C password. If the values match, the I2C security session is open, and the I2C_SSO_Dyn register is set to 01h. If the values do not match, the I2C security session is closed and I2C_SSO_dyn register is set to 00h. I2C_SSO_Dyn is a Dynamic register, it can be checked via I2C host to know If I2C security session is open. Figure 30.

It cannot be used to update any of the RF passwords. After the write cycle, the new I2C password value is automatically activated. The I2C password value can only be modified after issuing a valid I2C present password command. DS10925 - Rev 9 page 72/200 ST25DV04K ST25DV16K ST25DV64K I2C password management Following a Start condition, the bus master sends a device select code with the Read/ Write bit (R W ) reset to 0 and the Chip Enable bit E2 at 1. The device acknowledges this, as shown in Figure 31. I2C Write Password Sequence, and waits for the two I2C password address bytes, 09h and 00h. The device responds to each address byte with an acknowledge bit, and then waits for the four password data bytes, the validation code, 07h, and a resend of the eight password data bytes. The most significant byte of the password is sent first, followed by the least significant bytes. It is necessary to send twice the 64-bit password to prevent any data corruption during the write sequence. If the two 64-bit passwords sent are not exactly the same, the ST25DVxxx does not modify the I2C password value. When the bus master generates a Stop condition immediately after the Ack bit (during the tenth bit time slot), the internal write cycle is triggered. A Stop condition at any other time does not trigger the internal write cycle. During the internal write cycle, the serial data (SDA) signal is disabled internally, and the device does not respond to any requests. Caution: I2C write password command data transits via the 256-Bytes fast transfer mode's buffer. Consequently fast transfer mode must be deactivated before issuing a write password command, otherwise command is NotACK (after address LSB), and programming is not done and device goes in standby mode.

The ST25DVxxx communicates via the 13.56 MHz carrier electromagnetic wave on which incoming data are demodulated from the received signal amplitude modulation (ASK: amplitude shift keying). The received ASK wave is 10% or 100% modulated with a data rate of 1.6 Kbit/s using the 1/256 pulse coding mode or a data rate of 26 Kbit/s using the 1/4 pulse coding mode. Outgoing data are generated by the ST25DVxxx load variation using Manchester coding with one or two subcarrier frequencies at 423 kHz and 484 kHz. Data are transferred from the ST25DVxxx at 6.6 Kbit/s in low data rate mode and 26 Kbit/s in high data rate mode. The ST25DVxxx supports the 53 Kbit/s in high data rate mode in one subcarrier frequency at 423 kHz. The ST25DVxxx follows ISO/IEC 15693 or NFC Forum Type 5 recommendation for radio-frequency power and signal interface and for anticollision and transmission protocol. 7.1 RF communication 7.1.1 Access to a ISO/IEC 15693 device The dialog between the “RF reader” and the ST25DVxxx takes place as follows: These operations use the RF power transfer and communication signal interface described below (see Power transfer, Frequency and Operating field). This technique is called RTF (Reader talk first). • activation of the ST25DVxxx by the RF operating field of the reader, • transmission of a command by the reader (ST25DVxxx detects carrier amplitude modulation) • transmission of a response by the ST25DVxxx(ST25DVxxx modulates is load clocked at subcarrier rate) Operating field The ST25DVxxx operates continuously between the minimum and maximum values of the electromagnetic field H defined in Table 253. RF characteristics. The Reader has to generate a field within these limits. Power transfer Power is transferred to the ST25DVxxx by radio frequency at 13.56 MHz via coupling antennas in the ST25DVxxx and the Reader. The RF operating field of the reader is transformed on the ST25DVxxx antenna to an AC voltage which is rectified, filtered and internally regulated. During communications, the amplitude modulation (ASK) on this received signal is demodulated by the ASK demodulator Frequency The ISO 15693 standard defines the carrier frequency (fC) of the operating field as 13.56 MHz ±7 kHz. 7.2 RF communication and energy harvesting As the current consumption can affect the AC signal delivered by the antenna, RF communications with ST25DVxxx are not guaranteed during voltage delivery on the energy harvesting analog output V_EH. RF communication can disturb and possibly stop Energy Harvesting mode. 7.3 Fast transfer mode mailbox access in RF Thanks to dedicated commands, the RF interface has the possibility to check Mailbox availability, and the capability to access it directly to put or get a message from it (see Section 5.1 Fast transfer mode (FTM) for specific features). DS10925 - Rev 9 page 74/200 ST25DV04K ST25DV16K ST25DV64K RF protocol description 7.4 RF protocol description 7.4.1 Protocol description The transmission protocol (or simply “the protocol”) defines the mechanism used to exchange instructions and data between the VCD (Vicinity Coupling Device) and the ST25DVxxx in both directions. It is based on the concept of “VCD talks first”. This means that a ST25DVxxx does not start transmitting unless it has received and properly decoded an instruction sent by the VCD. The protocol is based on an exchange of: • a request from the VCD to the ST25DVxxx, • a response from the ST25DVxxx to the VCD. Each request and each response are contained in a frame. The frame are delimited by a Start of Frame (SOF) and End of Frame (EOF). The protocol is bit-oriented. The number of bits transmitted in a frame is a multiple of eight (8), that is an integer number of bytes. A single-byte field is transmitted least significant bit (LSBit) first. A multiple-byte field is transmitted least significant byte (LSByte) first and each byte is transmitted least significant bit (LSBit) first. Figure 32. ST25DVxxx protocol timing VCD Request frame Request frame Response frame ST25DVxxx Timing 7.4.2 t1 Response frame t2 t1 t2 ST25DVxxx states referring to RF protocol The ST25DVxxx can be in one of four states: • Power-off • Ready • Quiet • Selected Transitions between these states are specified in Figure 33. ST25DVxxx state transition diagram and Table 92. ST25DVxxx response depending on Request_flags. Power-off state The ST25DVxxx is in the Power-off state when it does not receive enough energy from the VCD. Ready state The ST25DVxxx is in the Ready state when it receives enough energy from the VCD. When in the Ready state, the ST25DVxxx answers any request where the Select_flag is not set.

Selected state In the Selected state, the ST25DVxxx answers any request in all modes (see Section 7.4.3 Modes): • Request in Select mode with the Select_flag set • Request in Addressed mode if the UID matches • Request in Non-Addressed mode as it is the mode for general requests Table 92.

The intention of the state transition method is that only one ST25DVxxx should be in the Selected state at a time. When the Select_flag is set to 1, the request shall NOT contain a unique ID. When the address_flag is set to 0, the request shall NOT contain a unique ID. DS10925 - Rev 9 page 76/200 ST25DV04K ST25DV16K ST25DV64K RF protocol description 7.4.3 Modes The term “mode” refers to the mechanism used in a request to specify the set of ST25DVxxx devices that shall execute the request. Addressed mode When the Address_flag is set to 1 (Addressed mode), the request contains the Unique ID (UID) of the addressed ST25DVxxx. Any ST25DVxxx that receives a request with the Address_flag set to 1 compares the received Unique ID to its own. If it matches, then the ST25DVxxx executes the request (if possible) and returns a response to the VCD as specified in the command description. If the UID does not match, then it remains silent. Non-addressed mode (general request) When the Address_flag is cleared to 0 (Non-Addressed mode), the request does not contain a Unique ID. Select mode When the Select_flag is set to 1 (Select mode), the request does not contain a unique ID. The ST25DVxxx in the Selected state that receives a request with the Select_flag set to 1 executes it and returns a response to the VCD as specified in the command description. Only the ST25DVxxx in the Selected state answers a request where the Select_flag is set to 1. The system design ensures that only one ST25DVxxx can be in the Select state at a time. 7.4.4 Request format The request consists of: • an SOF, • flags, • a command code, • parameters and data, • a CRC, • an EOF. Table 93. General request format SOF 7.4.5 Request_flags Command code Parameters Data 2 byte CRC EOF Request flags In a request, the “flags” field specifies the actions to be performed by the ST25DVxxx and whether corresponding fields are present or not. The flags field consists of eight bits. Bit 3 (Inventory_flag) of the request flag defines the contents of the four MSBs (bits 5 to 8). When bit 3 is reset (0), bits 5 to 8 define the ST25DVxxx selection criteria. When bit 3 is set (1), bits 5 to 8 define the ST25DVxxx Inventory parameters.

Timing definition t1: ST25DVxxx response delay Upon detection of the rising edge of the EOF received from the VCD, the ST25DVxxx waits for a t1nom time before transmitting its response to a VCD request or switching to the next slot during an inventory process. Values of t1 are given in Table 100. Timing values. t2: VCD new request delay t2 is the time after which the VCD may send an EOF to switch to the next slot when one or more ST25DVxxx responses have been received during an Inventory command. It starts from the reception of the EOF from the ST25DVxxxs. The EOF sent by the VCD may be either 10% or 100% modulated regardless of the modulation index used for transmitting the VCD request to the ST25DVxxx. t2 is also the time after which the VCD may send a new request to the ST25DVxxx, as described in Figure 32. ST25DVxxx protocol timing. Values of t2 are given in Table 100. Timing values. t3: VCD new request delay when no response is received from the ST25DVxxx t3 is the time after which the VCD may send an EOF to switch to the next slot when no ST25DVxxx response has been received. The EOF sent by the VCD may be either 10% or 100% modulated regardless of the modulation index used for transmitting the VCD request to the ST25DVxxx. From the time the VCD has generated the rising edge of an EOF: • If this EOF is 100% modulated, the VCD waits for a time at least equal to t3min for 100% modulation before sending a new EOF. • If this EOF is 10% modulated, the VCD waits for a time at least equal to t3min for 10% modulation before sending a new EOF.

But in case of an invalid command, in a general manner, the ST25DVxxx will behave as follows: 1. if flag usage is incorrect, the error code 03h will be issued only if the right UID is used in the command, otherwise no response will be issued. 2. error 02h will be issued if the custom command is used with the manufacturer code different from the ST one Another case is if I2C is busy. In this case, any RF command (except Inventory, Select, Stay quiet and Reset to ready) will get 0Fh error code as response only: • if select flag and address flags are not set at the same time (except if ST25DVxxx is in quiet state) • if select flag is set and ST25DVxxx is in selected state. For all other commands, if I2C is busy, no response will be issued by ST25DVxxx.

Note: In case of error, no response is sent by ST25DVxxx. 7.6.5 Stay Quiet On receiving the Stay Quiet command, the ST25DVxxx enters the Quiet state if no error occurs, and does NOT send back a response. There is NO response to the Stay Quiet command even if an error occurs. The Option_flag is not supported. The Inventory_flag must be set to 0. When in the Quiet state: • the ST25DVxxx does not process any request if the Inventory_flag is set, • the ST25DVxxx processes any Addressed request.

It is not required to present the new password value until the ST25DVxxx power-down. Caution: DS10925 - Rev 9 If ST25DVxxx is powered through VCC, removing VCC during Write Password command can abort the command. As a consequence, before writing a new password, RF user should check if VCC is ON, by reading EH_CTRL_Dyn register bit 3 (VCC_ON), and eventually ask host to maintain or to shut down VCC, during the Write Password command in order to avoid password corruption. To make the application more robust, it is recommended to use addressed or selected mode during write password operations to get the traceability of which tags/UID have been programmed page 123/200 ST25DV04K ST25DV16K ST25DV64K RF commands Table 207.

For the low data rate, same subcarrier frequency or frequencies is/are used. In this case, the number of pulses is multiplied by 4 and all times increase by this factor. For the Fast commands using one subcarrier, all pulse numbers and times are divided by 2. A.1 Bit coding using one subcarrier A.1.1 High data rate For the fast commands, a logic 0 starts with four pulses at 423.75 kHz (fC/32) followed by an unmodulated time of 9.44 µs, as shown in Figure 86. Figure 86. Logic 0, high data rate, fast commands 18.88 µs For the Fast commands, a logic 1 starts with an unmodulated time of 9.44 µs followed by four pulses of 423.75 kHz (fC/32), as shown in Figure 87. Figure 87. Logic 1, high data rate, fast commands 18.88 µs A.1.2 Low data rate For the Fast commands, a logic 0 starts with 16 pulses at 423.75 kHz (fC/32) followed by an unmodulated time of 37.76 µs, as shown in Figure 88.
