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
on address pin A9. Address pins A6,
A1, and A0 must be as shown in
Table 4
. In addition,
when verifying sector protection, the sector address
must appear on the appropriate highest order address
bits (see Tables 2 and 3).
Table 4
shows the remaining
address bits that are don’t care. When all necessary
bits are set as required, the programming equipment
may then read the corresponding 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
Table 12, on page 28
.
This method does not require V
ID
. See
“Command Def-
initions” on page 23
for details on using the autoselect
mode.
Table 4.

L = Logic Low = V
IL
, H = Logic High = V
IH
, SA = Sector Address, X = Don’t care.
Note:
Outputs for data bits DQ8–DQ15 are for BYTE#=V
IH
. DQ8–DQ15 are don’t care when BYTE#=V
IL
.
