Legend:  
X = Don’t care  
RA = Read Address of memory location to be read.  
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.  
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.  
WC = Word Count. Number of write buffer locations to load minus 1.  
Notes:  
1. See Table 1 for description of bus operations.  
2. All values are in hexadecimal.  
3. Shaded cells indicate read cycles. All others are write cycles.  
4. 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.  
9. If WP# protects highest address sector, data is 98h for factory  
locked and 18h for not factory locked. If WP# protects lowest  
address sector, data is 88h for factory locked and 08h for not  
factor locked.  
10. Data is 00h for an unprotected sector group and 01h for a  
protected sector group.  
11. Total number of cycles in command sequence is determined by  
number of words written to write buffer. Maximum number of  
cycles in command sequence is 21, including "Program Buffer to  
Flash" command.  
12. Command sequence resets device for next command after  
aborted write-to-buffer operation.  
13. Unlock Bypass command is required prior to Unlock Bypass  
Program command.  
14. Unlock Bypass Reset command is required to return to read  
mode when device is in unlock bypass mode.  
5. No unlock or command cycles required when device is in read  
mode.  
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 the autoselect command sequence is a read  
cycle. Data bits DQ15–DQ8 are don’t care. Except for RD, PD  
and WC. See Autoselect Command Sequence section for more  
information.  
15. 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.  
8. Device ID must be read in three cycles.  
16. Erase Resume command is valid only during Erase Suspend  
mode.
