Effective safety application procedures and knowledge are required to minimize risk of electrical shock hazard when using this EVM. The user should be technically qualified to operate this EVM, including having full knowledge of risks associated in working with electrically live and hazardous voltages commonly found in development platforms. Careful review of General Texas Instruments High Voltage Evaluation Module (TI HV EVM) User Safety Guidelines at the end of this document is required prior to using this EVM. 1 Introduction The Microreader RI-STU-MRD2 is a reader module with advanced features that is backward compatible with the RI-STU-MRD1 module. It features new protocols and commands to communicate with TI lowfrequency (LF) half-duplex (HDX), and advanced transponders for programming and tuning after the production phase. In addition to the DIL module size, which is compatible with the RI-STU-MRD1, the reader is also available in a smaller SMD module RI-SMD-MRD2. Both modules can be used as direct drop-in replacements for the RI-STU-MRD1. This document describes the hardware and communication protocols of the RI-STU-MRD2 module. Figure 1.

The Microreader supports serial and USB data communications between a PC and TI transponders. The Microreader supports TTL data communications through its serial communications interface (SCI), which allows communication to a standard interface when using an additional communications driver (for example, RS232 or RS422). In addition, a USB interface is available and requires only a few external components. For easy access to the USB port from the PC side, the reader is managed as a COM port. The Microreader can be controlled remotely either by providing certain inputs with the corresponding voltage level or by sending commands to the SCI or USB. The Microreader can be driven either with or without synchronization. Synchronization can be either wireless or wired to enable reliable operation in multi-reader environments. Two outputs show the reader status and inform the user about a successful command execution. The Microreader supports all available TI LF HDX transponders. The supply voltage can vary between 2.7 V and 5.5 V. A voltage regulator and level shifters are implemented to maintain the specified supply range. A microcontroller generates the transmit signal, demodulates the receive signal, and manages the two host interfaces. 2.7 V to 5.5 V USB Antenna 47 µH Serial Port Microreader 2 Module Control Status Figure 2.

This output is at GND level until the Microreader starts its read cycle, at which time it goes to VSL until the read, program, or lock cycle is finished. RDEN- (2) Input for wired synchronization. Pull this pin to VSL to prevent the Microreader output stage from transmitting. Pull this pin to GND to enable transmitting. The Microreader samples this input at the start of its own read, program, or lock cycle; therefore, if the input goes to VSL after a cycle is started, the cycle is not interrupted. RDEN- is a high-impedance input and must be tied to GND via a suitable resistor (27 kΩ) when not in use. To trigger a single read when the Microreader is idle, pull the RDEN- pin logic high for 100 µs. The single read starts on the falling edge of the 100-µs pulse. SCBU049 – August 2012 Submit Documentation Feedback Microreader RI-STU-MRD2 Copyright © 2012, Texas Instruments Incorporated 13 Product Description www.ti.com RESET- (4) Pull this pin to GND to hold the Microreader in reset. If the reset pin is not used, it can be left disconnected (it is internally pulled up). Minimum pulse duration to perform a reset is 1 ms. After a reset, the processor requires between 28 ms and 132 ms (typically 72 ms) before it can receive new instructions via the serial communications interface. RXD (5) Input configured to receive serial data at 9600 Baud (default, configurable up to 115k Baud), 1 start bit, 8 data bits, no parity, and 1 stop bit. TXD (6) Output configured to transmit serial data at 9600 Baud (default, configurable up to 115k Baud), 1 start bit, 8 data bits, no parity, and 1 stop bit. USB_D-, USB_D+ (7, 8) USB data transmit and receive USB_VBUS (28) USB power voltage GND (15, 25) Pins 15 and 25 are ground for the logic part. ANT1 (16) Antenna pin for the connection of a 47-µH low-Q antenna. ANTCAP (17) To use an antenna of lower inductance, connect a suitable capacitor between ANT1 and ANTCAP. This additional capacitor (ceramic, 100 VDC) is in parallel with the 30-nF resonance capacitor on the Microreader. ANT2 (19) Antenna pin (GND) for the connection of a 47-µH low-Q antenna. GNDP (21) Ground for the output stage. VSP (22) Positive supply voltage (2.7 V to 5.5 V, same as VSL) for the output stage. VSL (24) Positive supply voltage (2.7 V to 5.5 V, same as VSP) for the logic part. CRDM (26) Apply a logic high signal to run the Microreader in a continuous charge-only read mode. When the CRDM pin is logic low, the Microreader is in an idle state waiting for commands via the serial interface or for a trigger signal (RDEN-) to start a single read out cycle. CRDM is a high-impedance input and must be tied to either VSL or GND via a suitable resistor (27 kΩ). WLSC (27) Enables or disables wireless synchronization. To enable the wireless synchronization, pin 27 must be pulled to VSL. When wireless synchronization is enabled, the Microreader tries to synchronize its transmit signals with any other readers in range. To disable wireless synchronization, pull pin 27 to GND. Pin 27 is a high-impedance input and must be tied to either VSL or GND via a suitable resistor (27 kΩ). Wireless synchronization can also be turned on or off by a command on the serial interface. This command has priority over the WLSC input. OKT (29) This output is set to logic high for approximately 60 ms if a valid transponder was read. It can be connected externally to an LED to indicate the result of the read cycle (see Section 6.4.3.30). 14 Microreader RI-STU-MRD2 SCBU049 – August 2012 Submit Documentation Feedback Copyright © 2012, Texas Instruments Incorporated Product Description www.ti.com STAT (30) Pin 30 is set to logic low when the RF transmitter is activated. Supplying an external LED with this signal makes the status of the Microreader visible (see Section 6.4.3.31). 4.3 Power Supply There are two separate (2.7 V to 5.5 V) supplies to the Microreader, one for the output stage (VSP) and the other for the logic (VSL). Both supplies, VSP and VSL, must have the same voltage. On power up, VSL should rise faster than 0.1 V/ms to ensure reliable operation. To avoid problems with noise conducted by the supply lines if a single supply is used, use separate connections from a common decoupling capacitor to the Microreader. NOTE: The RF module must not be supplied by most switched mode power supplies (SMPS). This is because most SMPS operate at frequencies near 50 kHz. The harmonics of the generated field can interfere with the receiver. Therefore, use linear regulated power supplies. An SMPS with a fundamental operating frequency of 200 kHz or higher can be used. 4.4 Synchronization There are two possible methods of wired synchronization: • Connect a pulse waveform to all RDEN- input pins of the Microreaders to be synchronized. Hold the pulse at VSL and drop it to GND for 100 µs every 200 ms. • Connect all SYNC outputs to an OR gate and then connect the output of the OR gate as an input to the RDEN- of each Microreader to be synchronized. Wireless synchronization of the Microreader is very effective at synchronizing to adjacent readers; however, problems can occur if the antennas are positioned so that a transponder is within range of two readers at the same time. In this situation, one reader could synchronize with the transponder instead of with the other reader. When the WLSC input is active, the Microreader is in wireless synchronization mode. Wireless synchronization can also be turned on or off by a corresponding command via the serial interface. During execution of this command, it has priority over the WLSC input. After the command execution, the status of the WLSC input is considered again. NOTE: It is not recommended to have both wired and wireless synchronization on, because the synchronization could be unreliable. It is recommended to use bus drivers for wired synchronization with other Microreaders and to prevent ESD damage. Wired or wireless synchronization prolongs the cycle time by 20 ms (typical). 4.5 Serial Port and USB Communication Communication between host and reader is done by either the serial port or the USB port. Both ports can accept commands. No setup or switch between these ports is necessary. Each response is sent to the port from which the command was received. If the CRDM pin is active, the response is sent to the serial port, but when a USB connection is established the response is sent to the USB port. The factory default for both interfaces is 9600 Baud, 1 start bit, 8 data bits, no parity, and 1 stop bit; they can be connected directly to a communications driver to allow a half duplex communication with a PC via its serial communications interface (for example: RS232 or RS422)or USB Interface. See Section 6 for details on the communication protocols.

When it receives an Xoff (0x13) the Microreader stops its current operation and stops transmitting data via the serial port. It stays in idle mode until Xon (0x11) is received when it continues with the previous mode or command. During this idle period, the Microreader accepts commands via the serial port, however, it waits for its execution until Xon is received. In this idle period, the Microreader can store only one command. NOTE: While receiving a command protocol from the serial port, Xon or Xoff is interpreted as normal data without affecting the serial communication. 4.7 Trigger Mode When the Microreader is in idle mode, it is possible to trigger a single charge-only read with a power burst duration of 50 ms by taking the RDEN- pin to logic high for 100 µs. The single read starts on the falling edge of the 100-µs pulse. If a transponder command is sent to the Microreader via the SCI while RDEN- is in a logic high state (waiting position), a falling edge on RDEN- triggers execution of the command. In waiting position the Microreader can only store one command. This means that if two commands were to be sent to the Microreader while it is in the waiting position, the second command overwrites the first one. 4.8 Continuous Mode When the CRDM input is active, the Microreader enters a continuous charge-only read mode using power burst duration of 50 ms. The serial data input takes priority over the CRDM input such that if a serial command is received, it is executed regardless of the state of the CRDM input. After the execution of the serial data command, the Microreader continues with the previous read mode. In the default continuous read mode, only those valid RO, R/W, or MPT IDs that differ from the previously read ID, or valid IDs read after a NO READ, are transferred via the SCI (Normal Mode). The Microreader can be set to transfer all valid IDs that are read (Line Mode) by means of a corresponding serial data command. Without synchronization the Microreader has a reading frequency of approximately ten readouts per second using power burst duration of 50 ms. 16 Microreader RI-STU-MRD2 SCBU049 – August 2012 Submit Documentation Feedback Copyright © 2012, Texas Instruments Incorporated Product Description www.ti.com 4.9 Demonstration Circuit Figure 6 shows a demonstration circuit.

Because of the low Q, the system does not need to be tuned. Table 5 shows the typical parameters for a circular air coil antenna. Table 5.

Without built-in damping, the data may not be correctly received. • The antenna may be detuned if there is any metal in the area. The following formula provides a method of calculating the approximate Q factor of the antenna: Q= 2πfL R (1) Where, f = 134200 Hz (Frequency = 134.2 kHz) L = Inductance (H) R = Series resistance (Ω) Equation 2 shows an example for: Inductance (L) = 47 µH Resistance (R) = 2.2 Ω Q= = 2 × π × 134200 × 0.000047 2.2 39.636 2.2 (2) = 18 18 Microreader RI-STU-MRD2 SCBU049 – August 2012 Submit Documentation Feedback Copyright © 2012, Texas Instruments Incorporated Communication Between Host and Reader www.ti.com 5.2 Adapting the Inductance Range If the antenna is outside of the required inductance range of 46 to 48 µH, adapt it to work with the Microreader by adding an external capacitor to it, either in series or in parallel. This external capacitor can change the inductance range by 5 µH. Equation 3 shows the formula to calculate the total resonance capacity. Ctot = 1 2 4π L Ant f 2 (3) If the antenna inductance is less than 46.1 µH, add an extra capacitor (externally) to the antenna between pin ANT1 and pin ANTCAP. Equation 4 shows the formula for the value of this capacitor. Cext = Ctot – 30 nF (4) If the antenna inductance is more than 47.9 µH, add an extra capacitor in series with the antenna between pin ANT2 and the antenna. Equation 5 shows the formula for the value of this capacitor. 1 1 1 = – Cext Ctot 30 nF 6 (5) Communication Between Host and Reader Communication between host and reader is done either by the serial port or the USB port. Both ports can accept commands. No setup or switch between these ports is necessary. Response is sent to the port from which the command was received. The USB port is configured as CDC (Communication Device Class). If connected to a PC, no special driver is required, but an INF file is required, which can be downloaded from the Microreader product folder on the TI web page. If the port is installed by the host, it is accessible as COM port. Data transfer is done in a binary format. No ASCII characters interpretation is done. Therefore, the use of the ASCII carriage return (CR) or line feed (LF) for the command termination is not possible. The reader assumes a command as terminated if the number of bytes specified after the 0x01 start byte is received, or if no new byte is received for 10 ms. The Microreader can process different communication protocols: It can interpret the protocol defined for the previous Microreader RI-STU-MRD1 with no restrictions. This protocol is referred to as Legacy Microreader Protocol (LMP). Based on this protocol, expansions are defined to support new functionality. These expansions are: • Bit Sequence Protocol (BSP) allows specification of a transponder downlink at bit level. • Easy Code Mode (ECM) Protocol allows specification of a transponder downlink with a minimum of parameters based on the specification of the device that is in use and the associated command. • Setup Mode Protocol (SM) is used to set up reader parameters or to manage functionality such as the inventory process. NOTE: It is recommended that all users take advantage of the Easy Code Mode (ECM) Protocol when possible. The use of the Legacy Microreader Protocol (LMP) should be restricted to users who migrate from the RI-STU-MRD1 module and have software already available. For special purposes, when the user wants do define a transponder protocol at bit level, the Bit Sequence Protocol (BSP) can be used.

Thus the application can validate the programming or lock response before a further cycle is started. If bit 2 (FBCC calculation) and bit 6 (Data) are set, the Microreader automatically calculates a two byte BCC over the data to be sent to the transponder and adds it to the protocol. When bits 2 and 6 are set, the PC must not send the 2 byte FBCC to the Microreader. Bit 4 (Power Pause Duration) is for future use and must not be set when addressing standard transponders.

It can be used for transponders that are not implemented in the Easy Code Mode ECM or if special features are required. Using this protocol requires deep knowledge about the used transponder because the downlink to the transponder must be defined bitwise. The response to a BSP command is the raw data received from the transponder including the Start Byte but without the Pre-Bits. 6.2.1 BSP Command Format Table 22 shows the BSP command format. Table 22.

The Length byte indicates the length in bytes of the following command and data fields. CMD1 to CMD3 are command bytes that are used to configure the behavior of the downlink, such as Power Bursts or Timing. Bit 8 of CMD1 and CMD2 must be 1, and Bit 8 of CMD3 must be 0. Power Burst 1 is an optional 16-bit value that defines the length of the Power Burst 1 in milliseconds (65 seconds maximum) Power Burst 2 is an optional 16-bit value that defines the length of the Power Burst 2 in milliseconds (65 seconds maximum) Number of TX Bits defines the length of the downlink to the transponder in bits. This value must be equal to or less then the number of data bits available in the Data section. If no Data is specified, this field is omitted. Data contains the data that is sent as downlink to the transponder. LSByte comes first. LSBit of LSByte is transmitted first. Number of RX Bytes is the number of bytes that are expected from the transponder during the uplink. Count starts at the first bit of the Start Byte. BCC is a 1-byte value of the Longitudinal Redundancy Check calculation (XORed bytes) for the preceding message. The calculation is performed on the whole command excluding the Start Byte. The fields Power Burst 1, Power Burst 2, Number of TX Bits, and Data are optional, depending on the value of CMD1.

Finally, special handling of the transmit mode, for instance if the carrier stays on after the data is transmitted, can be set. Table 23.

One single bit of the downlink is composed of a time where the carrier is off (Toff) and a time where the carrier is on (Ton). Normally the carrier off (Toff) comes first. This can be changed to Ton first by setting this bit.

It should free the user from knowing the timings, meanings of all of the bits, the sequence in which they must be sent, or how they are received from the transponder. Only a minimum of information is necessary to construct an ECM reader command. This includes the device that is used in form of a device code, the command that should be sent to the device and, if any, the parameters that belongs to the command.

Bit 3 "Parameter Error" of Status 1 is set to 1 if the length of the Parameter and Data field does not match with the Device and Command combination or if one of the Parameters is out of the allowed bounds. If any of these errors occurred, no downlink is sent to the transponder. The response has the Length Byte set to 0x02, because no Data is returned. If Bit 0 of Status 1 has a value of 0 reader to transponder protocol status is shown. If no Error occurred or no status information is available, Status Bytes 1 and Status Byte 2 have a value of 0x00, which means the last command was executed successfully. If the Status Byte 1 has a value of 0x00 and Status Byte 2 has a value that is not equal 0x00, then Status Byte 2 shows not an error condition but only additional status information.

The measurement of the low-bit frequency is not possible in this mode. This means that automatic CTrimming (Setup Mode 0x43) and the automatic detection of the demodulation threshold do not work in combination with the RFM module. 100 Microreader RI-STU-MRD2 SCBU049 – August 2012 Submit Documentation Feedback Copyright © 2012, Texas Instruments Incorporated General Texas Instruments High Voltage Evaluation Module (TI HV EVM) User Safety Guidelines WARNING Always follow TI's set-up and application instructions, including use of all interface components within their recommended electrical rated voltage and power limits. Always use electrical safety precautions to help ensure your personal safety and the safety of those working around you. Contact TI's Product Information Center http://support.ti.com for further information. Save all warnings and instructions for future reference. Failure to follow warnings and instructions may result in personal injury, property damage, or death due to electrical shock and burn hazards. The term TI HV EVM refers to an electronic device typically provided as an open framed, unenclosed printed circuit board assembly. It is intended strictly for use in development laboratory environments, solely for qualified professional users having training, expertise and knowledge of electrical safety risks in development and application of high voltage electrical circuits. Any other use and/or application are strictly prohibited by Texas Instruments. If you are not suitable qualified, you should immediately stop further use of the TI HV EVM. 1. 2. Work Area Safety: (a) Keep work area clean and orderly. (b) Qualified observer(s) must be present any time circuits are energized. (c) Effective barriers and signage must be present in the area where the TI HV EVM and its interface electronics are energized, indicating operation of accessible high voltages may be present, for the purpose of protecting inadvertent access. (d) All interface circuits, power supplies, evaluation modules, instruments, meters, scopes, and other related apparatus used in a development environment exceeding 50Vrms/75VDC must be electrically located within a protected Emergency Power Off (EPO) protected power strip. (e) Use a stable and nonconductive work surface. (f) Use adequately insulated clamps and wires to attach measurement probes and instruments. No freehand testing whenever possible. Electrical Safety: As a precautionary measure, it is always a good engineering practice to assume that the entire EVM may have fully accessible and active high voltages. (a) De-energize the TI HV EVM and all its inputs, outputs, and electrical loads before performing any electrical or other diagnostic measurements. Revalidate that TI HV EVM power has been safely de-energized. (b) With the EVM confirmed de-energized, proceed with required electrical circuit configurations, wiring, measurement equipment hook-ups, and other application needs, while still assuming the EVM circuit and measuring instruments are electrically live. (c) Once EVM readiness is complete, energize the EVM as intended. WARNING While the EVM is energized, never touch the EVM or its electrical circuits as they could be at high voltages capable of causing electrical shock hazard. 3. Personal Safety: (a) Wear personal protective equipment; for example, latex gloves or safety glasses with side shields or protect EVM in an adequate lucent plastic box with interlocks from accidental touch. Limitation for safe use: EVMs are not to be used as all or part of a production unit. IMPORTANT NOTICE Texas Instruments Incorporated and its subsidiaries (TI) reserve the right to make corrections, enhancements, improvements and other changes to its semiconductor products and services per JESD46C and to discontinue any product or service per JESD48B.
