The device supports the standard Serial Peripheral Interface (SPI), and a Dual SPI. ESMT's memory devices reliably store memory data even after 100,000 programming and erase cycles. The memory array can be organized into 8,192 programmable pages of 256 byte each. 1 to 256 byte can be programmed at a time with the Page Program instruction. The device also can be programmed to decrease total chip programming time with Auto Address Increment (AAI) programming. Elite Semiconductor Memory Technology Inc. The device features sector erase architecture. The memory array is divided into 512 uniform sectors with 4K byte each; 32 uniform blocks with 64K byte each. Sectors can be erased individually without affecting the data in other sectors. Blocks can be erased individually without affecting the data in other blocks. Whole chip erase capabilities provide the flexibility to revise the data in the device. The device has Sector, Block or Chip Erase but no page erase. The sector protect/unprotect feature disables both program and erase operations in any combination of the sectors of the memory.

The Once the device enters Hold mode, SO will be in high impedance state while SI and SCK can be VIL or VIH. HOLD mode begins when the SCK active low state coincides with the falling edge of the HOLD signal. The HOLD mode ends when the HOLD signal's rising edge coincides with the SCK active low state. If the falling edge of the HOLD signal does not coincide with the SCK active low state, then the device enters Hold mode when the SCK next reaches the active low state. If CE is driven active high during a Hold condition, it resets the internal logic of the device. As long as HOLD signal is low, the memory remains in the Hold condition. To resume communication with the device, HOLD must be driven active high, and CE must be driven active low. See Figure 23 for Hold timing. Similarly, if the rising edge of the HOLD signal does not coincide with the SCK active low state, then the device exits in S CK HO L D A ctive A ctive Ho ld Ho ld A ctive Figure 1: HOLD Condition Waveform WRITE PROTECTION F25L16PA provides software Write Protection. The Write-Protect pin ( WP ) enables or disables the lock-down function of the status register. The Block-Protection bits (BP2, BP1, BP0, and BPL) in the status register provide Write protection to the memory array and the status register. See Table 4 for Block-Protection description. Write Protect Pin ( WP ) Table 4: Conditions to Execute Write-Status-Register (WRSR) Instruction WP BPL Execute WRSR Instruction L 1 Not Allowed L 0 Allowed H X Allowed The Write-Protect ( WP ) pin enables the lock-down function of the BPL bit (bit 7) in the status register. When WP is driven low, the execution of the Write Status Register (WRSR) instruction is determined by the value of the BPL bit (see Table 4). When WP is high, the lock-down function of the BPL bit is disabled. Elite Semiconductor Memory Technology Inc.

The instruction bus cycles are 8 bits each for commands (Op Code), data, and addresses. Prior to executing any Page Program, Auto Address Increment (AAI) Programming, Write Status Register, Sector Erase, Block Erase, or Chip Erase instructions, the Write Enable (WREN) instruction must be executed first. The complete list of the instructions is provided in Table 5. All instructions are synchronized off a high to low before an instruction is entered and must be driven high after the last bit of the instruction has been shifted in (except for Read, Read ID, Read Status Register, Read Electronic Signature instructions). Any low to high transition on CE , before receiving the last bit of an instruction bus cycle, will terminate the instruction in progress and return the device to the standby mode. low transition of CE .

This allows data to be transferred from the device at twice the rate of standard SPI devices. This instruction is for quickly downloading code from Flash to RAM upon power-up or for applications that cache code- segments to RAM for execution. The Fast Read Dual Output instruction is initiated by executing an 8-bit command, 3BH, followed by address bits [A23 -A0] and a dummy byte. CE must remain active low for the duration of the Fast Read Dual Output cycle. See Figure 4 for the Fast Read Dual Output sequence. Figure 4: Fast Read Dual Output Sequence Elite Semiconductor Memory Technology Inc. Publication Date: Jul. 2009 Revision: 1.4 12/33 ESMT F25L16PA Page Program (PP) The Page Program instruction allows many bytes to be programmed in the memory. The bytes must be in the erased state (FFH) when initiating a Program operation. A Page Program instruction applied to a protected memory area will be ignored. latched data are discarded and the last 256 bytes Data are guaranteed to be programmed correctly within the same page. If less than 256 bytes Data are sent to device, they are correctly programmed at the requested addresses without having any effects on the other bytes of the same page. Prior to any Write operation, the Write Enable (WREN) instruction CE must be driven high before the instruction is executed. The user may poll the BUSY bit in the software status register or wait TPP for the completion of the internal self-timed Page Program operation. While the Page Program cycle is in progress, the Read Status Register instruction may still be accessed for checking the status of the BUSY bit. It is recommended to wait for a duration of TBP1 before reading the status register to check the BUSY bit. The BUSY bit is a 1 during the Page Program cycle and becomes a 0 when the cycle is finished and the device is ready to accept other instructions again. After the Page Program cycle has finished, the Write-Enable-Latch (WEL) bit in the Status Register is cleared to 0. See Figure 5 for the Page Program sequence. must be executed. CE must remain active low for the duration of the Page Program instruction. The Page Program instruction is initiated by executing an 8-bit command, 02H, followed by address bits [A23-A0]. Following the address, at least one byte Data is input (the maximum of input data can be up to 256 bytes). If the 8 least significant address bits [A7-A0] are not all zero, all transmitted data that goes beyond the end of the current page are programmed from the start address of the same page (from the address whose 8 least significant bits [A7-A0] are all zero).

Publication Date: Jul. 2009 Revision: 1.4 13/33 ESMT F25L16PA Auto Address Increment (AAI) WORD Program The AAI program instruction allows multiple bytes of data to be programmed without re-issuing the next sequential address location. This feature decreases total programming time when the multiple bytes or entire memory array is to be programmed. An AAI program instruction pointing to a protected memory area will be ignored. The selected address range must be in the erased state (FFH) when initiating an AAI program instruction. While within AAI WORD programming sequence, the only valid instructions are AAI WORD program operation, RDSR, WRDI. Users have three options to determine the completion of each AAI WORD program cycle: hardware detection by reading the SO; software detection by polling the BUSY in the software status register or wait TBP. Refer to End of Write Detection section for details. Prior to any write operation, the Write Enable (WREN) instruction must be executed. The AAI WORD program instruction is initiated by executing an 8-bit command, ADH, followed by address bits [A23 -A0]. Following the addresses, two bytes of data is input sequentially. The data is input sequentially from MSB (bit 7) to LSB (bit 0). The first byte of data (D0) will be programmed into the initial address [A23 -A1] with A0 =0; the second byte of data (D1) will be programmed into the initial address [A23 -A1] with A0 =1. CE must be driven high before the AAI WORD program instruction is executed. The user must check the busy status before entering the next valid command. Once the device indicates it is no longer busy, data for next two sequential addresses may be programmed and so on. When the last desired byte had been entered, check the busy status using the hardware method or the RDSR instruction and execute the WRDI instruction, to terminate AAI. User must check busy status after WRDI to determine if the device is ready for any command. Please refer to Figure 8 and Figure 9. There is no wrap mode during AAI programming; once the highest unprotected memory address is reached, the device will exit AAI operation and reset the Write-Enable-Latch bit (WEL = 0) and the AAI bit (AAI=0). End of Write Detection There are three methods to determine completion of a program cycle during AAI WORD programming: hardware detection by reading the SO, software detection by polling the BUSY bit in the Software Status Register or wait TBP. The Hardware End of Write Detection method is described in the section below. Hardware End of Write Detection The Hardware End of Write Detection method eliminates the overhead of polling the BUSY bit in the Software Status Register during an AAI Word program operation. The 8-bit command, 70H, configures the SO pin to indicate Flash busy status during AAI WORD programming (refer to Figure 6). The 8-bit command, 70H, must be executed prior to executing an AAI WORD program instruction. Once an internal programming operation begins, asserting CE will immediately drive the status of the internal flash Figure 6: Enable SO as Hardware RY/ BY during AAI Programming Elite Semiconductor Memory Technology Inc. status on the SO pin. A "0" Indicates the device is busy; a "1" Indicates the device is ready for the next instruction. De-asserting CE will return the SO pin to tri-state. The 8-bit command, 80H, disables the SO pin to output busy status during AAI WORD program operation and return SO pin to output Software Status Register data during AAI WORD programming (refer to Figure 7).

CE must be driven low before the EWSR instruction is entered and must be driven high before the EWSR instruction is executed. Publication Date: Jul. 2009 Revision: 1.4 18/33 ESMT F25L16PA Write Status Register (WRSR) The Write Status Register instruction writes new values to the BP2, BP1, BP0, and BPL bits of the status register. CE must be driven low before the command sequence of the WRSR instruction is entered and driven high before the WRSR instruction is executed. See Figure 16 for EWSR or WREN and WRSR instruction sequences. Executing the Write Status Register instruction will be ignored when WP is low and BPL bit is set to "1". When the WP is low, the BPL bit can only be set from "0" to "1" to lock down the status register, but cannot be reset from "1" to "0". When WP is high, the lock-down function of the BPL bit is disabled and the BPL, BP0, BP1,and BP2 bits in the status register can all be changed. As long as BPL bit is set to 0 or WP pin is driven high (VIH) prior to the low-to-high transition of the CE pin at the end of the WRSR instruction, the bits in the status register can all be altered by the WRSR instruction. In this case, a single WRSR instruction can set the BPL bit to "1" to lock down the status register as well as altering the BP0; BP1 and BP2 bits at the same time. See Table 4 for a summary description of WP and BPL functions.

The additional 4K bytes secured OTP sector is independent from main array, which may use to store unique serial number for system identifier. User must unprotect whole array (BP0=BP1=BP2=0), prior to any Program operation in OTP sector. After entering the secured OTP mode, only the secured OTP sector can be accessed and user can only follow the Read or Program procedure with OTP address range (address bits [A23 -A12] must be "0"). The secured OTP data cannot be updated again once it is lock down or has been programmed. In secured OTP mode, WRSR command will ignore the input data and lock down the secured OTP sector (OTP_lock bit =1). To exit secured OTP mode, user must execute WRDI command. RES can be used to verify the secured OTP status as shown in Table 6. Figure 17: Enter OTP Mode (ENSO) Sequence Elite Semiconductor Memory Technology Inc.

Read-Electronic-Signature (RES) The RES instruction can be used to read the 8-bit Electronic Signature of the device on the SO pin. The RES instruction can provide access to the Electronic Signature of the device (except while an Erase, Program or WRSR cycle is in progress), Any RES instruction executed while an Erase, Program or WRSR cycle is in progress is no decoded, and has no effect on the cycle in progress. In OTP mode, user also can execute RES to confirm the status.

The device information can be read from executing the 8-bit command, 9FH. Following the JEDEC Read-ID instruction, the 8-bit manufacturer's ID, 8CH, is output from the device. After that, a 16-bit device ID is shifted out on the SO pin. Byte1, 8CH, identifies the manufacturer as ESMT. Byte2, 20H, identifies the memory type as SPI Flash. Byte3, 15H, identifies the device as F25L16PA. The instruction sequence is shown in Figure 19. The JEDEC Read ID instruction is terminated by a low to high transition on CE at any time during data output. If no other command is issued after executing the JEDEC Read-ID instruction, issue a 00H (NOP) command before going into Standby Mode ( CE =VIH).

This command is backward compatible to all ESMT SPI devices and should be used as default device identification when multiple versions of ESMT SPI devices are used in one design. The device information can be read from executing an 8-bit command, 90H, followed by address bits [A23 -A0]. Following the Read-ID instruction, the manufacturer's ID is located in address 00000H and the device ID is located in address 00001H. Once the device is in Read-ID mode, the manufacturer's and device ID output data toggles between address 00000H and 00001H until terminated by a low to high transition on CE .
