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

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-

“Autoselect Command Sequence” for details on using

the autoselect mode.
