Note for Tables 2 and 3: Address range is A16:A-1 in byte mode and A16:A0 in word mode. See the “Word/Byte Configuration”
sectionfor 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.
When using programming equipment, the autoselect
mode requires V_ID (11.5 V to 12.5 V) on address pin
A9. Address pins A6, A1, and A0 must be as shown in
Autoselect Codes (High Voltage Method) table. In addi-
tion, when verifying sector protection, the sector
address must appear on the appropriate highest order
address bits. Refer to the corresponding Sector
Address Tables. The Command Definitions table
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 the Command Defini-
tions table. This method does not require V_ID. See
“Autoselect Command Sequence” for details on using
the autoselect mode.
