Legend

X = Don’t care

RA = Address of the memory 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 the WE# or CE# pulse, whichever happens first.

SA = Address of the sector to be verified (in autoselect mode) or erased.

Address bits Amax–A16 uniquely select any sector.

WBL = Write Buffer Location. The address must be within the same write

buffer page as PA.

WC = Word Count is the number of write buffer locations to load minus 1.

Notes

1. See Table 7.1 on page 19 for description of bus operations.

2. All values are in hexadecimal.

3. All bus cycles are write cycles unless otherwise noted.

4. Data bits DQ15-DQ8 are don’t cares for unlock and command cycles.

5. Address bits AMAX:A16 are don’t cares for unlock and command cycles,

unless SA or PA required. (AMAX is the Highest Address pin.).

6. No unlock or command cycles required when reading array data.

7. 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).

8. See Table 7.2 on page 22 for device ID values and definitions.

9. The fourth, fifth, and sixth cycles of the autoselect command sequence are

read cycles.

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

See Autoselect on page 21 for more information. This is same as PPB

Status Read except that the protect and unprotect statuses are inverted

here.

11. The data value for DQ7 is “1” for a serialized, protected Secured Silicon

Sector region and “0” for an unserialized, unprotected region. See

Table 7.3 on page 22 for data and definitions.

12. Command is valid when device is ready to read array data or when device

is in autoselect mode.

13. Depending on the number of words written, the total number of cycles may

be from 6 to 37.

14. Command sequence returns device to reading array after being placed in

a Write-to-Buffer-Abort state. Full command sequence is required if

resetting out of abort while in Unlock Bypass mode.

15. The Unlock-Bypass command is required prior to the Unlock-Bypass-

Program command.

16. The Unlock-Bypass-Reset command is required to return to reading array

data when the device is in the unlock bypass mode.

17. The system can read and program/program suspend 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.

18. The Erase Resume/Program Resume command is valid only during the

Erase Suspend/Program Suspend modes.

19. The Exit command returns the device to reading the array.
