Command Definitions Tables
Legend:
BA = Address of bank switching to autoselect mode, bypass mode, or
erase operation. Determined by A21:A19, see Tables
more detail.
PA = Program Address (A21:A0). Addresses latch on falling edge of
WE# or CE# pulse, whichever happens later.
PD = Program Data (DQ15:DQ0) written to location PA. Data latches
on rising edge of WE# or CE# pulse, whichever happens first.
Notes:
1.
2. All values are in hexadecimal.
3. Shaded cells in table denote read cycles. All other cycles are
4. During unlock and command cycles, when lower address bits are
5. No unlock or command cycles required when bank is reading
6. Reset command is required to return to reading array (or to
7. Cycle 4 of autoselect command sequence is a read cycle. See
8. The data is 80h for factory locked and 00h for not factory locked.
