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.
BA = Address of the bank that is being switched to autoselect
mode, is in bypass mode, or is being erased.
9. The device ID is 41h for top boot device, and 81h for bottom
boot device.
10. The data is 82h for factory locked and 02h for not
factory
locked.
11. The data is 00h for an unprotected sector and 01h for a
protected sector.
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.
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 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.
6. No unlock or command cycles required when bank is in
read mode.
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. See the Autoselect Command Sequence section
for more information.
