IL
)
Legend:
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.
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 A19–A15 uniquely select any sector.

See Table
1
for description of bus operations.
All values are in hexadecimal.
Shaded cells indicate read cycles. All others are write
cycles.
4.
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.
No unlock or command cycles required when device is in
read mode.
5.
6.
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.
7.
Fourth cycle of autoselect command sequence is a read
cycle. Data bits DQ15–DQ8 are don’t care. See
Autoselect
Command Sequence
section or more information.
Device ID must be read in three cycles.
8.
9.
Data is 00h for an unprotected sector group and 01h for a
protected sector group.
10. Unlock Bypass command is required prior to Unlock
Bypass Program command.
11. Unlock Bypass Reset command is required to return to
read mode when device is in unlock bypass mode.
12. System may read and program in non-erasing sectors, or
enter autoselect mode, when in Erase Suspend mode.
Erase Suspend command is valid only during a sector
erase operation.
