Legend:  
X = Don’t care  
PD = Data to be programmed at location PA. Data latches on the  
rising edge of WE# or CE# pulse, whichever happens first.  
RA = Address of the memory location to be read.  
SA = Address of the sector to be verified (in autoselect mode) or  
erased. Address bits A16–A14 uniquely select any sector.  
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:  
1. See Table 1 for description of bus operations.  
7. The fourth cycle of the autoselect command sequence is a  
read operation.  
2. All values are in hexadecimal.  
8. The data is 00h for an unprotected sector and 01h for a  
protected sector. See “Autoselect Command Sequence” for  
more information.  
3. Except when reading array or autoselect data, all command  
bus cycles are write operations.  
4. No unlock or command cycles required when reading array  
data.  
9. The system may read 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.  
5. 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).  
10. The Erase Resume command is valid only during the Erase  
Suspend mode.  
6. The device accepts the three-cycle reset command  
sequence for backward compatibility.
