Table 1. Pin Descriptions Symbol A0 A22-A1 Type INPUT Name and Function ADDRESS INPUTS: Lowest address input in byte mode (BYTE#=VIL : x8 bit). Address is internally latched during an erase or a program cycle. This pin is not used in word mode (BYTE#=VIH : x16 bit) ADDRESS INPUTS: Inputs for addresses during read, erase and program operations. Addresses are internally latched during an erase or a program cycle. DATA INPUTS/OUTPUTS: Inputs data and commands during CUI (Command User Interface) write cycles, outputs data during memory array, status register, query code, identifier code reads. Data pins float to high-impedance (High Z) when the chip or outputs are deselected. Data is internally latched during an erase or program cycle. DQ15-DQ8 pins are not used in byte mode (BYTE#=VIL : x8 bit). CHIP ENABLE: Activates the device's control logic, input buffers, decoders and sense amplifiers. When the device is de-selected, power consumption reduces to standby levels. Refer to Table 2 to determine whether the device is selected or de-selected depending on the state of CE0, CE1 and CE2. RESET: When low (VIL), RP# resets internal automation and inhibits erase and program operations, which provides data protection. RP#-high (VIH) enables normal operation. After power-up or reset mode, the device is automatically set to read array mode. RP# must be low during power-up/down. OUTPUT ENABLE: Gates the device's outputs during a read cycle. WRITE ENABLE: Controls writes to the CUI and array blocks. Addresses and data are latched on the first edge of CE0, CE1 or CE2 that disables the device or the rising edge of WE# (whichever occurs first).

STATUS: Indicates the status of the internal WSM (Write State Machine). When configured in level mode (default mode), STS acts as a RY/BY# pin (STS is VOL when OPEN DRAIN the WSM is executing internal erase or program algorithms). When configured in one of OUTPUT its pulse modes, STS can pulse to indicate erase/program completion. Refer to Table 9 for STS configuration. INPUT BYTE ENABLE: BYTE# VIL places the device in byte mode (x8). In this mode, DQ15DQ8 is floated (High Z) and A0 is the lowest address input. BYTE# VIH places the device in word mode (x16) and A1 is the lowest address input. MONITORING POWER SUPPLY VOLTAGE: VPEN is not used for power supply pin. With VPENVPENLK, block erase, (page buffer) program, block lock configuration and OTP program cannot be executed and should not be attempted. DEVICE POWER SUPPLY (2.7V-3.6V): With VCCVLKO, all write attempts to the flash memory are inhibited. Device operations at invalid VCC voltage (refer to DC Characteristics) produce spurious results and should not be attempted. INPUT/OUTPUT POWER SUPPLY (2.7V-3.6V): Power supply for all input/output pins. GROUND: Do not float any ground pins. NO CONNECT: Lead is not internally connected; it may be driven or floated.

In STS configuration = "00", STS is VOL when the WSM is STS configuration 01 The output of the STS pin is the control signal to indicate executing internal erase or program algorithms. that the erase operation is completed and the flash memory is available for the next operation. STS configuration codes "01", "10" and "11" are all pulse modes such that the STS pin pulses low then high when the operation indicated by the configuration code is completed. STS configuration 10 The output of the STS pin is the control signal to indicate that the program operation is completed and the flash memory is available for the next operation. STS configuration 11 The output of the STS pin is the control signal to indicate that the erase or program operation is completed and the flash memory is available for the next operation. NOTE: 1. When the device is configured in one of the pulse modes, the STS pin pulses low with a typical pulse width of 250ns.

NOTES: 1. The timing characteristics for reading the status register during block erase, (page buffer) program, block lock configuration and OTP program operations are the same as during read-only operations. Refer to AC Characteristics for read-only operations. 2. A write operation can be initiated and terminated with either CE0, CE1, CE2 or WE#. 3. Sampled, not 100% tested. 4. Write pulse width low (tWP) is defined from the first edge of CE0, CE1 or CE2 that enables the device or the falling edge of WE# (whichever occurs last) to the first edge of CE0, CE1 or CE2 that disables the device or the rising edge of WE# (whichever occurs first). Hence, tWP=tWLWH=tELEH=tWLEH=tELWH. 5. Write pulse width high (tWPH) is defined from the first edge of CE0, CE1 or CE2 that disables the device or the rising edge of WE# (whichever occurs first) to the first edge of CE0, CE1 or CE2 that enables the device or the falling edge of WE# (whichever occurs last). Hence, tWPH=tWHWL=tEHEL=tWHEL=tEHWL. 6. VPEN should be held at VPEN=VPENH until determination of block erase, (page buffer) program, block lock configuration or OTP program success (SR.1/3/4/5=0). 7. Refer to Table 5 for valid address and data for block erase, (page buffer) program, block lock configuration and OTP program. 8. The output delay time tAVQV or tELQV is required in addition to tWHGL (tEHGL) for read operations after command writes. 9. The timing is defined from the first edge of CE0, CE1 or CE2 that enables the device. 10. The timing is defined from the first edge of CE0, CE1 or CE2 that disables the device. 11. STS timings depend on STS configuration.

Excludes external system-level overhead. 3. Sampled, but not 100% tested. 4. A latency time is required from writing suspend command (the first edge of CE0, CE1 or CE2 that disables the device or the rising edge of WE#) until SR.7 going "1" or STS going High Z. 5. If the interval time from a Block Erase Resume command to a subsequent Block Erase Suspend command is shorter than tERES and its sequence is repeated, the block erase operation may not be finished. 6. These values are valid when the page buffer is full, and the start address is aligned on a 16-word/ 32-byte boundary. 7. Program time per byte (tWHQV1/ tEHQV1) is 12.5s/byte (typical). Program time per word (tWHQV2/ tEHQV2) is 25.0s/word (typical).
