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.
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.
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.
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
To access the autoselect codes in-system, the host system can
issue the autoselect command via the command register.
