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 A20 - A12 select a unique sector.
BA = Address of the bank that is being switched to autoselect mode, is in bypass mode, or is being erased.
Note:
1. See Table 1 for description of bus operations.
2. All values are in hexadecimal.
3. Except for the read cycle and the fourth cycle of the autoselect command sequence, all bus cycles are write cycles.
4. Data bits I/O15-I/O8 are don’t care in command sequences. Except for RD and PD.
5. Unless otherwise noted, address bits A20-A11 are don’t cares.
6. No unlock or command cycles required when bank is reading array data.
7. The Reset command is required to return to reading array data (or to the erase-suspend-read mode if previously in Erase
Suspend) when a bank is in the autoselect mode, or if I/O5 goes high (while the bank is providing status information).
8. The fourth cycle of the autoselect command sequence is a read cycle. The system must provide the bank address to obtain
the manufacture ID, or device ID information. Data bits I/O15-I/O8 are don’t care. See the Autoselect Command Sequence
section for more information.
9. The data is 00h for an unprotected sector/sector block and 01h for a protected sector/sector block.
10. The Unlock Bypass command is required prior to the Unlock Bypass Program Command.
11. The Unlock Bypass Reset command is required to return to reading array data when the bank is in the unlock bypass mode.
12. The system may read and program in non-erasing sectors, or enter the autoselect mode, when in the Erase Suspend mode.
The Erase Suspend command is valid only during a sector erase operation, and require the bank address.
13. The Erase Resume command is valid only during the Erase.
14. Command is valid when device is ready to read array data or when device is in autoselect mode.
15. Once a reset command is applied, software temporary unprotect is exit to return to read array data. But under erase
suspend condition, this command is still effective even a reset command has been applied. The reset command which can
deactivate the software temporary unprotect command is useful only after the erase command is complete.
