Autoselect Code Table

PROGRAM or ERASE operation is not executing, the RESET

operation is completed within a time of tREADY. The system

can read data tRH after the RESET\ pin returns to VIH.

Refer to the “AC Characteristics” tables for RESET\

parameters.

Output Disable Mode

When the OE\ input is at VIH, output from the device is

disabled. The output pins are placed in the high Impedance

State.

Autoselect Mode

The autoselect mode provides manufacturer and device

identification, and sector protection verification through

identifier codes output via the appropriate Byte DQ’s. 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 (modified to support

multi-byte devices, or supplied from the programming

equipment provider as such), the autoselect mode requires

VID (11.5v to 12.5v) on address pin A9. Address pins A6,

A1, and A0 must be as shown in the Autoselect Table below.

In addtion, when verifying sector protection, the sector address

must appear on the appropriate highest order address bits. When

all necessary bits have been set as required, the programming

equipment may then read the corresponding identifier code on

the appropriate Byte DQ’s.

To access the autoselect codes in-system, the host system can

issue the autoselect command via the command register.
