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 are latched on the falling edge of the WE# or CE#

pulse.

PD = Data to be programmed at location PA. Data is latched

on the rising edge of WE# or CE# pulse.

SA = Address of the sector to be erased or verified. Address

bits A20–A16 uniquely select any sector.

Notes:

1. See Table 1 for descriptions 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 are don’t care for unlock and command

cycles, except when PA or SA is required.

5. No unlock or command cycles required when device is in

read mode.

6. The Reset command is required to return to the read

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

goes high.

7. The fourth cycle of the autoselect command sequence is

a read cycle.

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

protected sector.

9. The Unlock Bypass command is required prior to the

Unlock Bypass Program command.

10. The Unlock Bypass Reset command is required to return

to reading array data when the device is in the Unlock

Bypass mode.

11. The system may read and program functions 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.

12. The Erase Resume command is valid only during the

Erase Suspend mode.
