Macronix Proprietary 5 Rev. 1.8, August 06, 2020 MX25L12845G 2. GENERAL DESCRIPTION MX25L12845G is 128Mb bits Serial NOR Flash memory, which is configured as 16,777,216 x 8 internally. When it is in two or four I/O mode, the structure becomes 67,108,864 bits x 2 or 33,554,432 bits x 4. MX25L12845G features a serial peripheral interface and software protocol allowing operation on a simple 3-wire bus while it is in single I/O mode. The three bus signals are a clock input (SCLK), a serial data input (SI), and a serial data output (SO). Serial access to the device is enabled by CS# input. When it is in two I/O read mode, the SI pin and SO pin become SIO0 pin and SIO1 pin for address/dummy bits input and data output. When it is in four I/O read mode, the SI pin, SO pin, WP# and RESET# pin (of the 8-pin packages) become SIO0 pin, SIO1 pin, SIO2 pin and SIO3 pin for address/dummy bits input and data output. The MX25L12845G MXSMIO® (Serial Multi I/O) provides sequential read operation on the whole chip. After program/erase command is issued, auto program/erase algorithms which program/erase and verify the specified page or sector/block locations will be executed. Program command is executed on byte basis, or page (256 bytes) basis, or word basis. Erase command is executed on 4K-byte sector, 32K-byte block, or 64K-byte block, or whole chip basis. To provide user with ease of interface, a status register is included to indicate the status of the chip. The status read command can be issued to detect completion status of a program or erase operation via WIP bit. Advanced security features enhance the protection and security functions, please see security features section for more details. When the device is not in operation and CS# is high, it is put in standby mode. The MX25L12845G utilizes Macronix's proprietary memory cell, which reliably stores memory contents even after 100,000 program and erase cycles. Table 1.

DATA PROTECTION During power transition, there may be some false system level signals which result in inadvertent erasure or programming. The device is designed to protect itself from these accidental write cycles. The state machine will be reset as standby mode automatically during power up. In addition, the control register architecture of the device constrains that the memory contents can only be changed after specific command sequences have completed successfully. In the following, there are several features to protect the system from the accidental write cycles during VCC powerup and power-down or from system noise. • Valid command length checking: The command length will be checked whether it is at byte base and completed on byte boundary. • Write Enable (WREN) command: WREN command is required to set the Write Enable Latch bit (WEL) before other commands to change data. • Deep Power Down Mode: By entering deep power down mode, the flash device also is under protected from writing all commands except Release from deep power down mode command (RDP) and Read Electronic Signature command (RES), and softreset command. • Advanced Security Features: there are some protection and security features which protect content from inadvertent write and hostile access.

Additional 4K-bit secured OTP for an unique identifier to provide an 4K-bit one-time program area for setting a device unique serial number. This may be accomplished in the factory or by an end systems customer. - Security register bit 0 indicates whether the secured OTP area is locked by factory or not. - The 4K-bit secured OTP area is programmed by entering secured OTP mode (with the Enter Security OTP command), and going through a normal program procedure. Exiting secured OTP mode is done by issuing the Exit Security OTP command. - Customer may lock-down the customer lockable secured OTP by writing WRSCUR(write security register) command to set customer lock-down bit1 as "1". Please refer to "Table 12. Security Register Definition" for security register bit definition and "Table 3. 4K-bit Secured OTP Definition" for address range definition. - Note: Once lock-down whatever by factory or customer, it cannot be changed any more.

DEVICE OPERATION 1. Before a command is issued, status register should be checked to ensure device is ready for the intended operation. 2. When an incorrect command is written to this device, it enters standby mode and stays in standby mode until the next CS# falling edge. In standby mode, This device's SO pin should be High-Z. 3. When a correct command is written to this device, it enters active mode and stays in active mode until the next CS# rising edge. 4. Input data is latched on the rising edge of Serial Clock (SCLK) and data is shifted out on the falling edge of SCLK. The difference of Serial mode 0 and mode 3 is shown as "Figure 1. Serial Modes Supported". 5. For the following instructions: RDID, RDSR, RDSCUR, READ, FAST_READ, 2READ, DREAD, 4READ, QREAD, RDSFDP, RES, REMS, QPIID, RDDPB, RDSPB, RDLR, RDCR, the shifted-in instruction sequence is followed by a data-out sequence. After any bit of data being shifted out, the CS# can be high. For the following instructions: WREN, WRDI, WRSR, SE, BE32K, BE, CE, PP, 4PP, DP, ENSO, EXSO, WRSCUR, WPSEL, GBLK, GBULK, SUSPEND, RESUME, NOP, RSTEN, RST, EQIO, RSTQIO the CS# must go high exactly at the byte boundary; otherwise, the instruction will be rejected and not executed. 6. While a Write Status Register, Program, or Erase operation is in progress, access to the memory array is ignored and will not affect the current operation of Write Status Register, Program, or Erase. Figure 1. Serial Modes Supported CPOL CPHA shift in (Serial mode 0) 0 0 SCLK (Serial mode 3) 1 1 SCLK SI shift out MSB SO MSB Note: CPOL indicates clock polarity of Serial master, CPOL=1 for SCLK high while idle, CPOL=0 for SCLK low while not transmitting.

Release from Deep Power-down (RDP), Read Electronic Signature (RES) The Release from Deep Power-down (RDP) instruction is completed by driving Chip Select (CS#) High. When Chip Select (CS#) is driven High, the device is put in the Stand-by Power mode. If the device was not previously in the Deep Power-down mode, the transition to the Stand-by Power mode is immediate. If the device was previously in the Deep Power-down mode, though, the transition to the Stand-by Power mode is delayed by tRES1, and Chip Select (CS#) must remain High for at least tRES1(max), as specified in "Table 25. AC CHARACTERISTICS (Temperature = -40°C to 85°C, VCC = 2.7V - 3.6V)". Once in the Stand-by Power mode, the device waits to be selected, so that it can receive, decode and execute instructions. The RDP instruction is only for releasing from Deep Power Down Mode. Reset# pin goes low will release the Flash from deep power down mode. RES instruction is for reading out the old style of 8-bit Electronic Signature, whose values are shown as "Table 6. ID Definitions". This is not the same as RDID instruction. It is not recommended to use for new design. For new design, please use RDID instruction. The RDP and RES are allowed to execute in Deep power-down mode, except if the device is in progress of program/erase/write cycle; In this case, there is no effect on the current program/erase/write cycle that is in progress. Both SPI (8 clocks) and QPI (2 clocks) command cycle can accept by this instruction. The SIO[3:1] are don't care when during SPI mode. The RES instruction ends when CS# goes high, after the ID been read out at least once. The ID outputs repeatedly if continuously send the additional clock cycles on SCLK while CS# is at low. If the device was not previously in Deep Power-down mode, the device transition to standby mode is immediate. If the device was previously in Deep Power-down mode, there's a delay of tRES2 to transit to standby mode, and CS# must remain to high at least tRES2(max). Once in the standby mode, the device waits to be selected, so it can be receive, decode, and execute instruction. Figure 15.

Read Electronic Manufacturer ID & Device ID (REMS) The REMS instruction returns both the JEDEC assigned manufacturer ID and the device ID. The Device ID values are listed in "Table 6. ID Definitions". The REMS instruction is initiated by driving the CS# pin low and sending the instruction code "90h" followed by two dummy bytes and one address byte (A7-A0). After which the manufacturer ID for Macronix (C2h) and the device ID are shifted out on the falling edge of SCLK with the most significant bit (MSB) first. If the address byte is 00h, the manufacturer ID will be output first, followed by the device ID. If the address byte is 01h, then the device ID will be output first, followed by the manufacturer ID. While CS# is low, the manufacturer and device IDs can be read continuously, alternating from one to the other. The instruction is completed by driving CS# high. Figure 19.

Macronix Proprietary 32 Rev. 1.8, August 06, 2020 MX25L12845G Status Register The definition of the status register bits is as below: WIP bit. The Write in Progress (WIP) bit, a volatile bit, indicates whether the device is busy in program/erase/write status register progress. When WIP bit sets to 1, which means the device is busy in program/erase/write status register progress. When WIP bit sets to 0, which means the device is not in progress of program/erase/write status register cycle. WEL bit. The Write Enable Latch (WEL) bit is a volatile bit that is set to “1” by the WREN instruction. WEL needs to be set to “1” before the device can accept program and erase instructions, otherwise the program and erase instructions are ignored. WEL automatically clears to “0” when a program or erase operation completes. To ensure that both WIP and WEL are “0” and the device is ready for the next program or erase operation, it is recommended that WIP be confirmed to be “0” before checking that WEL is also “0” (Please refer to "Figure 28. WRSR flow"). If a program or erase instruction is applied to a protected memory area, the instruction will be ignored and WEL will clear to “0”. BP3, BP2, BP1, BP0 bits. The Block Protect (BP3, BP2, BP1, BP0) bits, non-volatile bits, indicate the protected area (as defined in "Table 2. Protected Area Sizes") of the device to against the program/erase instruction without hardware protection mode being set. To write the Block Protect (BP3, BP2, BP1, BP0) bits requires the Write Status Register (WRSR) instruction to be executed. Those bits define the protected area of the memory to against Page Program (PP), Sector Erase (SE), Block Erase 32KB (BE32K), Block Erase (BE) and Chip Erase (CE) instructions (only if Block Protect bits (BP3:BP0) set to 0, the CE instruction can be executed). The BP3, BP2, BP1, BP0 bits are "0" as default. Which is unprotected. QE bit. The Quad Enable (QE) bit is a non-volatile bit with a factory default of “0”. When QE is “0”, Quad mode commands are ignored; pins WP#/SIO2, NC/SIO3 and the RESET#/SIO3 of 8-pin package function as WP#, NC pin and RESET#, respectively. When QE is “1”, Quad mode is enabled and Quad mode commands are supported along with Single and Dual mode commands. Pins WP#/SIO2, NC/SIO3 and the RESET#/SIO3 of 8-pin package function as SIO2 and SIO3, respectively, and their alternate pin functions are disabled. Enabling Quad mode also disables the HPM feature and the RESET feature of 8-pin package. SRWD bit. The Status Register Write Disable (SRWD) bit, non-volatile bit, is operated together with Write Protection (WP#/SIO2) pin for providing hardware protection mode. The hardware protection mode requires SRWD sets to 1 and WP#/SIO2 pin signal is low stage. In the hardware protection mode, the Write Status Register (WRSR) instruction is no longer accepted for execution and the SRWD bit and Block Protect bits (BP3, BP2, BP1, BP0) are read only. The SRWD bit defaults to be "0". Table 7.

Flash memory will be configured after the CR bit is set. ODS bit The output driver strength (ODS1, ODS0) bits are volatile bits, which indicate the output driver level (as defined in "Table 9. Output Driver Strength Table") of the device. The Output Driver Strength is defaulted as 30 Ohms when delivered from factory. To write the ODS bits requires the Write Status Register (WRSR) instruction to be executed. TB bit The Top/Bottom (TB) bit is a non-volatile OTP bit. The Top/Bottom (TB) bit is used to configure the Block Protect area by BP bit (BP3, BP2, BP1, BP0), starting from TOP or Bottom of the memory array. The TB bit is defaulted as “0”, which means Top area protect. When it is set as “1”, the protect area will change to Bottom area of the memory device. To write the TB bits requires the Write Status Register (WRSR) instruction to be executed. PBE bit The Preamble Bit Enable (PBE) bit is a volatile bit. It is used to enable or disable the preamble bit data pattern output on dummy cycles. The PBE bit is defaulted as “0”, which means preamble bit is disabled. When it is set as “1”, the preamble bit will be enabled, and inputted into dummy cycles. To write the PBE bits requires the Write Status Register (WRSR) instruction to be executed. Table 8.

Write Status Register (WRSR) The WRSR instruction is for changing the values of Status Register Bits and Configuration Register Bits. Before sending WRSR instruction, the Write Enable (WREN) instruction must be decoded and executed to set the Write Enable Latch (WEL) bit in advance. The WRSR instruction can change the value of Block Protect (BP3, BP2, BP1, BP0) bits to define the protected area of memory (as shown in "Table 2. Protected Area Sizes"). The WRSR also can set or reset the Quad enable (QE) bit and set or reset the Status Register Write Disable (SRWD) bit in accordance with Write Protection (WP#/SIO2) pin signal, but has no effect on bit1(WEL) and bit0 (WIP) of the status register. The WRSR instruction cannot be executed once the Hardware Protected Mode (HPM) is entered. The sequence of issuing WRSR instruction is: CS# goes low→ send WRSR instruction code→ Status Register data on SI→Configuration Register data on SI→CS# goes high. The CS# must go high exactly at the 8 bits or 16 bits data boundary; otherwise, the instruction will be rejected and not executed. The self-timed Write Status Register cycle time (tW) is initiated as soon as Chip Select (CS#) goes high. The Write in Progress (WIP) bit still can be check out during the Write Status Register cycle is in progress. The WIP sets 1 during the tW timing, and sets 0 when Write Status Register Cycle is completed, and the Write Enable Latch (WEL) bit is reset. Figure 26.

The protected area, which is defined by BP3, BP2, BP1, BP0 and T/B bit, is at software protected mode (SPM). - When SRWD bit=1 and WP#/SIO2 is high, the WREN instruction may set the WEL bit can change the values of SRWD, BP3, BP2, BP1, BP0. The protected area, which is defined by BP3, BP2, BP1, BP0 and T/B bit, is at software protected mode (SPM) Note: If SRWD bit=1 but WP#/SIO2 is low, it is impossible to write the Status Register even if the WEL bit has previously been set. It is rejected to write the Status Register and not be executed. Hardware Protected Mode (HPM): - When SRWD bit=1, and then WP#/SIO2 is low (or WP#/SIO2 is low before SRWD bit=1), it enters the hardware protected mode (HPM). The data of the protected area is protected by software protected mode by BP3, BP2, BP1, BP0 and T/B bit and hardware protected mode by the WP#/SIO2 to against data modification. Note: To exit the hardware protected mode requires WP#/SIO2 driving high once the hardware protected mode is entered. If the WP#/SIO2 pin is permanently connected to high, the hardware protected mode can never be entered; only can use software protected mode via BP3, BP2, BP1, BP0 and T/B bit. If the system enter QPI or set QE=1, the feature of HPM will be disabled. Table 11.

Preamble Bit The Preamble Bit data pattern supports system/memory controller to determine valid window of data output more easily and improve data capture reliability while the flash memory is running in high frequency. Preamble Bit data pattern can be enabled or disabled by setting the bit4 of Configuration register (Preamble bit Enable bit). Once the CR is set, the preamble bit is inputted into dummy cycles. Enabling preamble bit will not affect the function of enhance mode bit. In Dummy cycles, performance enhance mode bit still operates with the same function. Preamble bit will output after performance enhance mode bit. The preamble bit is a fixed 8-bit data pattern (00110100). While dummy cycle number reaches 10, the complete 8 bits will start to output right after the performance enhance mode bit. While dummy cycle is not sufficient of 10 cycles, the rest of the preamble bits will be cut. For example, 8 dummy cycles will cause 6 preamble bits to output, and 6 dummy cycles will cause 4 preamble bits to output. Figure 39.

Burst Read The Burst Read feature allows applications to fill a cache line with a fixed length of data without using multiple read commands. Burst Read is disabled by default at power-up or reset. Burst Read is enabled by setting the Burst Length. When the Burst Length is set, reads will wrap on the selected boundary (8/16/32/64-bytes) containing the initial target address. For example if an 8-byte Wrap Depth is selected, reads will wrap on the 8-byte-page-aligned boundary containing the initial read address. To set the Burst Length, drive CS# low → send SET BURST LENGTH instruction code (C0h) → send WRAP CODE →drive CS# high. Refer to the table below for valid 8-bit Wrap Codes and their corresponding Wrap Depth. Data 00h 01h 02h 03h 1xh Wrap Around Yes Yes Yes Yes No Wrap Depth 8-byte 16-byte 32-byte 64-byte X Once Burst Read is enabled, it will remain enabled until the device is power-cycled or reset. The SPI and QPI mode 4READ read command supports the wrap around feature after Burst Read is enabled. To change the wrap depth, resend the Burst Read instruction with the appropriate Wrap Code. To disable Burst Read, send the Burst Read instruction with Wrap Code 1xh. QPI and SPI “EBh” support wrap around feature after wrap around is enabled. Both SPI (8 clocks) and QPI (2 clocks) command cycle can be accepted by this instruction. The SIO[3:1] are don't care during SPI mode. Figure 46.

Performance Enhance Mode - XIP (execute-in-place) The device could waive the command cycle bits if the two cycle bits after address cycle toggles. Performance enhance mode is supported in both SPI and QPI mode. In QPI mode, "EBh" and SPI “EBh” commands support enhance mode. The performance enhance mode is not supported in dual I/O mode. To enter performance-enhancing mode, P[7:4] must be toggling with P[3:0]; likewise P[7:0]=A5h, 5Ah, F0h or 0Fh can make this mode continue and skip the next 4READ instruction. To leave enhance mode, P[7:4] is no longer toggling with P[3:0]; likewise P[7:0]=FFh, 00h, AAh or 55h along with CS# is afterwards raised and then lowered. Issuing ”FFh” data cycle can also exit enhance mode. The system then will leave performance enhance mode and return to normal operation. After entering enhance mode, following CS# go high, the device will stay in the read mode and treat CS# go low of the first clock as address instead of command cycle. This sequence of issuing 4READ instruction especially useful in random access: CS# goes low→send 4READ instruction→3-bytes address interleave on SIO3, SIO2, SIO1 & SIO0→performance enhance toggling bit P[7:0]→ 4 dummy cycles (Default) →data out until CS# goes high → CS# goes low (The following 4READ instruction is not allowed, hence 8 cycles of 4READ can be saved comparing to normal 4READ mode) → 3-bytes random access address. To conduct the Performance Enhance Mode Reset operation in SPI mode, FFh data should be issued in 1I/O sequence. In QPI Mode, FFFFFFFFh data cycle, in 4 I/O should be issued. If the system controller is being Reset during operation, the flash device will return to the standard SPI operation. P/N: PM2145 Downloaded from Arrow.com.

Page Program (PP) The Page Program (PP) instruction is for programming memory bits to "0". One to 256 bytes can be sent to the device to be programmed. A Write Enable (WREN) instruction must be executed to set the Write Enable Latch (WEL) bit before sending the Page Program (PP). If more than 256 data bytes are sent to the device, only the last 256 data bytes will be accepted and the previous data bytes will be disregarded. The Page Program instruction requires that all the data bytes fall within the same 256-byte page. The low order address byte A[7:0] specifies the starting address within the selected page. Bytes that will cross a page boundary will wrap to the beginning of the selected page. The device can accept (256 minus A[7:0]) data bytes without wrapping. If 256 data bytes are going to be programmed, A[7:0] should be set to 0. The sequence of issuing PP instruction is: CS# goes low→ send PP instruction code→ 3-byte address on SI→ at least 1-byte on data on SI→ CS# goes high. The CS# must be kept to low during the whole Page Program cycle; The CS# must go high exactly at the byte boundary( the latest eighth bit of data being latched in), otherwise the instruction will be rejected and will not be executed. The self-timed Page Program Cycle time (tPP) is initiated as soon as Chip Select (CS#) goes high. The Write in Progress (WIP) bit still can be checked while the Page Program cycle is in progress. The WIP sets during the tPP timing, and clears when Page Program Cycle is completed, and the Write Enable Latch (WEL) bit is cleared. If the page is protected by BP bits (WPSEL=0; Block Protect Mode) or SPB (WPSEL=1; Individual Sector Protect Mode), the Page Program (PP) instruction will not be executed.

Please reference to "Write Protection Selection bit" Erase Fail bit. The Erase Fail bit indicates the status of last Erase operation. The bit will be set to "1" if the erase operation failed or the erase region is protected. It will be automatically cleared to "0" if the next erase operation succeeds. Please note that it does not interrupt or stop any operation in the flash memory. Program Fail bit. The Program Fail bit indicates the status of last Program operation. The bit will be set to "1" if the program operation failed or the program region is protected. It will be automatically cleared to "0" if the next program operation succeeds. Please note that it does not interrupt or stop any operation in the flash memory. Erase Suspend bit. Erase Suspend Bit (ESB) indicates the status of Erase Suspend operation. Users may use ESB to identify the state of flash memory. After the flash memory is suspended by Erase Suspend command, ESB is set to "1". ESB is cleared to "0" after erase operation resumes. Program Suspend bit. Program Suspend Bit (PSB) indicates the status of Program Suspend operation. Users may use PSB to identify the state of flash memory. After the flash memory is suspended by Program Suspend command, PSB is set to "1". PSB is cleared to "0" after program operation resumes. Secured OTP Indicator bit. The Secured OTP indicator bit indicates the Secured OTP area is locked by factory or not. When it is "0", it indicates non-factory lock; "1" indicates factory-lock. Lock-down Secured OTP (LDSO) bit. By writing WRSCUR instruction, the LDSO bit may be set to "1" for customer lock-down purpose. However, once the bit is set to "1" (lock-down), the LDSO bit and the 4K-bit Secured OTP area cannot be updated any more. While it is in 4K-bit secured OTP mode, main array access is not allowed.

Write Protection Selection (WPSEL) There are two write protection methods provided on this device, (1) Block Protection (BP) mode or (2) Individual Sector Protection mode. The protection modes are mutually exclusive. The WPSEL bit selects which protection mode is enabled. If WPSEL=0 (factory default), BP mode is enabled and Individual Sector Protection mode is disabled. If WPSEL=1, Individual Sector Protection mode is enabled and BP mode is disabled. The WPSEL command is used to set WPSEL=1. A WREN command must be executed to set the WEL bit before sending the WPSEL command. Please note that the WPSEL bit is an OTP bit. Once WPSEL is set to “1”, it cannot be programmed back to “0”. When WPSEL = 0: Block Lock (BP) protection mode, The memory array is write protected by the BP3-BP0 bits. When WPSEL =1: Individual Sector protection mode, Blocks are individually protected by their own SPB or DPB. On power-up, all blocks are write protected by the Dynamic Protection Bits (DPB) by default. The Individual Sector Protection instructions WRLR, RDLR, WRSPB, ESSPB, WRDPB, RDDPB, GBLK, and GBULK are activated. The BP3-BP0 bits of the Status Register are disabled and have no effect. Hardware protection is performed by driving WP#=0. Once WP#=0 all blocks and sectors are write protected regardless of the state of each SPB or DPB. The sequence of issuing WPSEL instruction is: CS# goes low → send WPSEL instruction to enable the Individual Sector Protect mode → CS# goes high. Figure 67.

Advanced Sector Protection Advanced Sector Protection can protect individual 4KB sectors in the bottom and top 64KB of memory and protect individual 64KB blocks in the rest of memory. There is one non-volatile Solid Protection Bit (SPB) and one volatile Dynamic Protection Bit (DPB) assigned to each 4KB sector at the bottom and top 64KB of memory and to each 64KB block in the rest of memory. A sector or block is write-protected from programming or erasing when its associated SPB or DPB is set to “1”. Please refer to "9-335. Sector Protection States Summary Table" for the sector state with the protection status of DPB/SPB bits. The figure below helps describing an overview of these methods. The device is default to the Solid mode when shipped from factory. The detail algorithm of advanced sector protection is shown as follows: Solid Protection mode permits the SPB bits to be modified after power-on or a reset.

Lock Register The Lock Register is a 16-bit one-time programmable register. Lock Register bit [6] is SPB Lock Down Bit (SPBLKDN) which is an unique bit assigned to control all SPB bit status. When SPBLKDN is 1, SPB can be changed. When it is locked as 0, all SPB can not be changed anymore, and SPBLKDN bit itself can not be altered anymore, either. The Lock Register is programmed using the WRLR (Write Lock Register) command. A WREN command must be executed to set the WEL bit before sending the WRLR command. Table 13.

Solid Protection Bits The Solid Protection Bits (SPBs) are nonvolatile bits for enabling or disabling write-protection to sectors and blocks. The SPB bits have the same endurance as the Flash memory. An SPB is assigned to each 4KB sector in the bottom and top 64KB of memory and to each 64KB block in the remaining memory. The factory default state of the SPB bits is “0”, which has the sector/block write-protection disabled. When an SPB is set to “1”, the associated sector or block is write-protected. Program and erase operations on the sector or block will be inhibited. SPBs can be individually set to “1” by the WRSPB command. However, the SPBs cannot be individually cleared to “0”. Issuing the ESSPB command clears all SPBs to “0”. A WREN command must be executed to set the WEL bit before sending the WRSPB or ESSPB command. The RDSPB command reads the status of the SPB of a sector or block. The RDSPB command returns 00h if the SPB is “0”, indicating write-protection is disabled. The RDSPB command returns FFh if the SPB is “1”, indicating write-protection is enabled. Note: If SPBLKDN=0, commands to set or clear the SPB bits will be ignored. Table 14.

Dynamic Protection Bits The Dynamic Protection Bits (DPBs) are volatile bits for quickly and easily enabling or disabling write-protection to sectors and blocks. A DPB is assigned to each 4KB sector in the bottom and top 64KB of memory and to each 64KB block in the rest of the memory. The DBPs can enable write-protection on a sector or block regardless of the state of the corresponding SPB. However, the DPB bits can only unprotect sectors or blocks whose SPB bits are “0” (unprotected). When a DPB is “1”, the associated sector or block will be write-protected, preventing any program or erase operation on the sector or block. All DPBs default to “1” after power-on or reset. When a DPB is cleared to “0”, the associated sector or block will be unprotected if the corresponding SPB is also “0”. DPB bits can be individually set to “1” or “0” by the WRDPB command. The DBP bits can also be globally cleared to “0” with the GBULK command or globally set to “1” with the GBLK command. A WREN command must be executed to set the WEL bit before sending the WRDPB, GBULK, or GBLK command. The RDDPB command reads the status of the DPB of a sector or block. The RDDPB command returns 00h if the DPB is “0”, indicating write-protection is disabled. The RDDPB command returns FFh if the DPB is “1”, indicating write-protection is enabled. Table 15.

The GBLK and GBULK instructions provide a quick method to set or clear all DPB bits at once. The WREN (Write Enable) instruction is required before issuing the GBLK/GBULK instruction. The sequence of issuing GBLK/GBULK instruction is: CS# goes low → send GBLK/GBULK (7Eh/98h) instruction →CS# goes high. The CS# must go high exactly at the byte boundary, otherwise, the instruction will be rejected and not be executed. 9-33-5.

Program/Erase Suspend/Resume The device allow the interruption of Sector-Erase, Block-Erase or Page-Program operations and conduct other operations. After issue suspend command, the system can determine if the device has entered the Erase-Suspended mode through Bit2 (PSB) and Bit3 (ESB) of security register. (please refer to "Table 12. Security Register Definition") Both SPI (8 clocks) and QPI (2 clocks) command cycle can accept by this instruction. The SIO[3:1] are don't care when during SPI mode. 9-35. Erase Suspend Erase suspend allow the interruption of all erase operations. After the device has entered Erase-Suspended mode, the system can read any sector(s) or Block(s) except those being erased by the suspended erase operation. Reading the sector or Block being erase suspended is invalid. After erase suspend, WEL bit will be clear, only read related, resume and reset command can be accepted, including: 03h, 0Bh, 3Bh, 6Bh, BBh, EBh, 5Ah, C0h, 06h, 04h, 2Bh, 9Fh, AFh, 05h, ABh, 90h, B1h, C1h, B0h, 30h, 66h, 99h, 00h, 35h, F5h, 15h, 2Dh, E2h, E0h. If the system issues an Erase Suspend command after the sector erase operation has already begun, the device will not enter Erase-Suspended mode until tESL time has elapsed. Erase Suspend Bit (ESB) indicates the status of Erase Suspend operation. Users may use ESB to identify the state of flash memory. After the flash memory is suspended by Erase Suspend command, ESB is set to "1". ESB is cleared to "0" after erase operation resumes. 9-36. Program Suspend Program suspend allows the interruption of all program operations. After the device has entered ProgramSuspended mode, the system can read any sector(s) or Block(s) except those be­ing programmed by the suspended program operation. Reading the sector or Block being program suspended is invalid. After program suspend, WEL bit will be cleared, only read related, resume and reset command can be accepted, including: 03h, 0Bh, 3Bh, 6Bh, BBh, EBh, 5Ah, C0h, 06h, 04h, 2Bh, 9Fh, AFh, 05h, ABh, 90h, B1h, C1h, B0h, 30h, 66h, 99h, 00h, 35h, F5h, 15h, 2Dh, E2h, E0h. Program Suspend Bit (PSB) indicates the status of Program Suspend operation. Users may use PSB to identify the state of flash memory.

ESB or PSB (suspend status bit) in Status register will be changed back to “0”. The operation of Write-Resume is as follows: CS# drives low → send write resume command cycle (30h) → drive CS# high. By polling Busy Bit in status register, the internal write operation status could be checked to be completed or not. The user may also wait the time lag of TSE, TBE, TPP for Sector-erase, Block-erase or Page-programming. WREN (command "06h") is not required to issue before resume. Please note that, if "performance enhance mode" is executed during suspend operation, the device can not be resumed. To restart the write command, disable the "performance enhance mode" is required. After the "performance enhance mode" is disabled, the write-resume command is effective. 9-38. No Operation (NOP) The “No Operation” command is only able to terminate the Reset Enable (RSTEN) command and will not affect any other command. Both SPI (8 clocks) and QPI (2 clocks) command cycle can accept by this instruction. The SIO[3:1] are don't care during SPI mode. 9-39. Software Reset (Reset-Enable (RSTEN) and Reset (RST)) The Software Reset operation combines two instructions: Reset-Enable (RSTEN) command and Reset (RST) command. It returns the device to standby mode. All the volatile bits and settings will be cleared then, which makes the device return to the default status as power on. To execute Reset command (RST), the Reset-Enable (RSTEN) command must be executed first to perform the Reset operation. If there is any other command to interrupt after the Reset-Enable command, the Reset-Enable will be invalid. Both SPI (8 clocks) and QPI (2 clocks) command cycle can accept by this instruction. The SIO[3:1] are don't care when during SPI mode. If the Reset command is executed during program or erase operation, the operation will be disabled, the data under processing could be damaged or lost. The reset time is different depending on the last operation. For details, please refer to "Table 21. Reset Timing-(Other Operation)" for tREADY2. P/N: PM2145 Downloaded from Arrow.com.

Read SFDP Mode (RDSFDP) The Serial Flash Discoverable Parameter (SFDP) standard provides a consistent method of describing the functional and feature capabilities of serial flash devices in a standard set of internal parameter tables. These parameter tables can be interrogated by host system software to enable adjustments needed to accommodate divergent features from multiple vendors. The concept is similar to the one found in the Introduction of JEDEC Standard, JESD68 on CFI. The sequence of issuing RDSFDP instruction is CS# goes low→send RDSFDP instruction (5Ah)→send 3 address bytes on SI pin→send 1 dummy byte on SI pin→read SFDP code on SO→to end RDSFDP operation can use CS# to high at any time during data out.

RESET Driving the RESET# pin low for a period of tRLRH or longer will reset the device. After reset cycle, the device is at the following states: - Standby mode - All the volatile bits such as WEL/WIP/SRAM lock bit will return to the default status as power on. If the device is under programming or erasing, driving the RESET# pin low will also terminate the operation and data could be lost. During the resetting cycle, the SO data becomes high impedance and the current will be reduced to minimum. Figure 84. RESET Timing CS# tRHSL SCLK tRH tRS RESET# tRLRH tREADY1 / tREADY2 Table 20.

POWER-ON STATE The device is in the states below when power-up: - Standby mode (please note it is not deep power-down mode) - Write Enable Latch (WEL) bit is reset The device must not be selected during power-up and power-down stage until the VCC reaches the following levels: - VCC minimum at power-up stage and then after a delay of tVSL - GND at power-down Please note that a pull-up resistor on CS# may ensure a safe and proper power-up/down level. An internal power-on reset (POR) circuit may protect the device from data corruption and inadvertent data change during power up state. When VCC is lower than VWI (POR threshold voltage value), the internal logic is reset and the flash device has no response to any command. For further protection on the device, if the VCC does not reach the VCC minimum level, the correct operation is not guaranteed. The write, erase, and program command should be sent after the below time delay: - tVSL after VCC reached VCC minimum level The device can accept read command after VCC reached VCC minimum and a time delay of tVSL. Please refer to the "Figure 92. Power-up Timing". Note: - To stabilize the VCC level, the VCC rail decoupled by a suitable capacitor close to package pins is recommended. (generally around 0.1uF) - At power-down stage, the VCC drops below VWI level, all operations are disable and device has no response to any command. The data corruption might occur during this stage if a write, program, erase cycle is in progress. P/N: PM2145 Downloaded from Arrow.com.

AC Timing at Device Power-Up" and "Figure 91. Power-Down Sequence" are for the supply voltages and the control signals at device power-up and power-down. If the timing in the figures is ignored, the device will not operate correctly. During power-up and power-down, CS# needs to follow the voltage applied on VCC to keep the device not to be selected. The CS# can be driven low when VCC reach Vcc(min.) and wait a period of tVSL. Figure 90.
