X = Don’t care
RA = Read Address of memory location to be read.
RD = Read Data read from location RA during read operation.
PA = Program Address. Addresses latch on falling edge of WE# or
CE# pulse, whichever happens later.

All values are in hexadecimal.
Shaded cells indicate read cycles. All others are write cycles.
During unlock and command cycles, when lower address bits are
555 or AAA as shown in table, address bits above A11 are don’t
care.
Unless otherwise noted, address bits A21–A11 are don’t cares.
No unlock or command cycles required when device is in read
mode.
Reset command is required to return to read mode (or to erase-
suspend-read mode if previously in Erase Suspend) when device
is in autoselect mode, or if DQ5 goes high while device is
providing status information.
Fourth cycle of autoselect command sequence is a read cycle.
Data bits DQ15–DQ8 are don’t care. See

Device ID must be read in three cycles.

PD = Program Data for location PA. Data latches on rising edge of
WE# or CE# pulse, whichever happens first.
SA = Sector Address of sector to be verified (in autoselect mode) or
erased. Address bits A21–A15 uniquely select any sector.
WBL = Write Buffer Location. Address must be within same write
buffer page as PA.
BC = Byte Count. Number of write buffer locations to load minus 1.
