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–A16 select a unique sector.

SGA = Address of the sector group to be verified. Address bits

A20–A18 select a unique sector group.

Notes:

1. See Table 1 for description of bus operations.

2. All values are in hexadecimal.

3. Except when reading array or autoselect data, all bus

cycles are write operations.

4. Address bits A20–A11 are don’t cares for unlock and

command cycles, unless SA or PA required.

5. No unlock or command cycles required when reading

array data.

6. The Reset command is required to return to reading array

data when device is in the autoselect mode, or if DQ5

goes high (while the device is providing status data).

7. The fourth cycle of the autoselect command sequence is

a read cycle.

8. The data is 00h for an unprotected sector group and 01h

for a protected sector group.See “Autoselect Command

Sequence” for more information.

9. Command is valid when device is ready to read array data

or when device is in autoselect mode.

10. The Unlock Bypass command is required prior to the

Unlock Bypass Program command.

11. The Unlock Bypass Reset command is required to return

to reading array data when the device is in the unlock

bypass mode.

12. 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.

13. The Erase Resume command is valid only during the

Erase Suspend mode.
