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 uniquely select any sector. Refer to
tables 3 and 4 for information on sector addresses.
BA = Address of the bank that is being switched to autoselect mode, is
in bypass mode, or is being erased. A20–A18 uniquely select a bank.
Notes:
1. See Table 1 for description of bus operations.
2. All values are in hexadecimal.
3. Except for the read cycle and the fourth, fifth, and sixth cycle of
the autoselect command sequence, all bus cycles are write
cycles.
4. Data bits DQ15–DQ8 are don’t care in command sequences,
except for RD and PD.
5. Unless otherwise noted, address bits A20–A11 are don’t cares for
unlock and command cycles, unless SA or PA is required.
6. No unlock or command cycles required when bank is reading
array data.
7. The Reset command is required to return to the read mode (or to
the erase-suspend-read mode if previously in Erase Suspend)
when a bank is in the autoselect mode, or if DQ5 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
manufacturer ID, device ID, or SecSi Sector factory protect
information. Data bits DQ15–DQ8 are don’t care. While reading
the autoselect addresses, the bank address must be the same
until a reset command is given. See the Autoselect Command
Sequence section for more information.
9. For models 01, 02, the device ID must be read across the fourth,
fifth, and sixth cycles.
10. The data is 82h for factory locked, 42h for customer locked, and
02h for not factory/customer locked.
11. The data is 00h for an unprotected sector/sector block and 01h
for a protected sector/sector block.
12. The Unlock Bypass command is required prior to the Unlock
Bypass Program command.
13. The Unlock Bypass Reset command is required to return to the
read mode when the bank is in the unlock bypass mode.
14. 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 requires the bank address.
15. The Erase Resume command is valid only during the Erase
Suspend mode, and requires the bank address.
16. Command is valid when device is ready to read array data or
when device is in autoselect mode.
