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.

Notes:

11. Data is 00h for an unprotected sector group and 01h for a protected sector group.

12. Total number of cycles in command sequence is determined by number of words written to write buffer. Maximum number of cycles in

13. Command sequence resets device for next command after aborted write-to-buffer operation.

14. Unlock Bypass command is required prior to Unlock Bypass Program command.

15. Unlock Bypass Reset command is required to return to read mode when device is in unlock bypass mode.

16. System may read and program in non-erasing sectors, or enter autoselect mode, when in Erase Suspend mode. Erase Suspend command

17. Erase Resume command is valid only during Erase Suspend mode.

18. Command is valid when device is ready to read array data or when device is in autoselect mode.

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 2AA as shown in table, address bits above A11 and data bits

above DQ7 are don’t care.

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 the autoselect command sequence is a read cycle. Data bits DQ15–DQ8 are don’t care. Except for RD, PD and WC.

SeeAutoselect Command Sequence on page 44

For S29GL064A and S29GL032A, Device ID must be read in three cycles.

For S29GL016A, Device ID must be read in one cycle.

command sequence is 21, including Program Buffer to Flash command.

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.

WC = Word Count. Number of write buffer locations to load minus 1.
