Note:  
Address range is A17:A-1 in byte mode and A17:A0 in word mode.See the “Word/Byte Configuration” section for more  
information.  
Autoselect Mode  
The autoselect mode provides manufacturer and  
device identification, and sector protection verification,  
through identifier codes output on DQ7–DQ0. This  
mode is primarily intended for programming equipment  
to automatically match a device to be programmed with  
its corresponding programming algorithm. However,  
the autoselect codes can also be accessed in-system  
through the command register.  
the sector address must appear on the appropriate  
highest order address bits (see Tables 2 and 3). Table  
4 shows the remaining address bits that are don’t care.  
When all necessary bits have been set as required, the  
programming equipment may then read the corre-  
sponding identifier code on DQ7–DQ0.  
To access the autoselect codes in-system, the host  
system can issue the autoselect command via the  
command register, as shown in Table 5. This method  
When using programming equipment, the autoselect  
mode requires V (11.5 V to 12.5 V) on address pin  
does not require V . See “Command Definitions” for  
ID  
ID  
A9. Address pins A6, A1, and A0 must be as shown in  
Table 4. In addition, when verifying sector protection,  
details on using the autoselect mode.
