Legend:  
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 A18-A12 uniquely select any sector.  
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.  
Notes:  
9. The data is 00h for an unprotected sector and 01h for a  
protected sector.  
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 the read mode 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.  
1. See Table 1 for description of bus operations.  
2. All values are in hexadecimal.  
3. Except for the read cycle and the fourth cycle of the autoselect  
command sequence, all bus cycles are write cycles.  
4. Data bits DQ15-DQ8 are don’t care in command sequences,  
except for RD and PD  
5. Unless otherwise noted, address bits A18-A11 are don’t cares.  
6. No unlock or command cycles required when device is in  
read mode.  
7. The Reset command is required to return to the read mode  
(or to the erase-suspend-read mode if previously in Erase  
Suspend) when a device is in the autoselect mode, or if DQ5  
goes high (while the device is providing status information).  
8. The fourth cycle of the autoselect command sequence  
is a read cycle. Data bits DQ15-DQ8 are don’t care. See the  
Autoselect Command Sequence section for more information.  
13. The Erase Resume command is valid only during the Erase  
Suspend mode.
