Legend:

X = Don't care

RA = Address of the memory location to be read.

RD = Data read from location RA during read operation.

PA = Address of the memory location to be programmed. Addresses latch on the falling edge of the WE or CE pulse, whichever

happens later.

PD = Data to be programmed at location PA. Data latches on the rising edge of WE or CE pulse, whichever happens first.

SA = Address of the sector to be verified (in autoselect mode) or erased. Address bits A16 - A15 select a unique sector.

Note:

1. See Table 1 for description of bus operations.

2. All values are in hexadecimal.

3. Except when reading array or autoselect data, all bus cycles are write operation.

4. Address bits A16 - A12 are don't cares for unlock and command cycles, unless SA or PA required.

5. No unlock or command cycles required when reading array data.

6. The Reset command is required to return to reading array data when device is in the autoselect mode, or if I/O5 goes high (while

the device is providing status data).

7. The fourth cycle of the autoselect command sequence is a read cycle.

8. The data is 00h for an unprotected sector and 01h for a protected sector. See "Autoselect Command Sequence" for more

information.

9. The system may read and program in non-erasing sectors, or enter the autoselect mode, when in the Erase Suspend mode.

10. The Erase Resume command is valid only during the Erase Suspend mode.

11. The time between each command cycle has to be less than 50μs
