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 Table 8.3 on page 18 and Table 8.4 on page 20 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 8.1 on page 14 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
Secured Silicon Region 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 Autoselect Command Sequence on page 33 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.
