Note:

Address range is A18: A-1 in byte mode and A18: 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 I/O7 - I/O0. 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 VID (11.5V 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 addition, 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

corresponding identifier code on I/O7 - I/O0.

To access the autoselect codes in-system, the host

system can issue the autoselect command via the

command register, as shown in the Command Definitions

table. This method does not require VID. See "Command

Definitions" for details on using the autoselect mode.
