Autoselect Mode
The autoselect mode provides manufacturer and de-
vice identification, and sector protection verification,
through identifier codes output on DQ7–DQ0. This
mode is primarily intended for programming equip-
ment to automatically match a device to be
programmed with its corresponding programming al-
gorithm. However, the autoselect codes can also be
accessed in-system through the command register.
When using programming equipment, the autoselect
mode requires V
ID
(9.0 V to 11.0 V) on address pin A9.
Address pins A6, A1, and A0 must be as shown in
Table 7
. In addition, when verifying sector protection,
the sector address must appear on the appropriate
highest order address bits (see Tables 3–6).
Table 7
shows the remaining address bits that are don’t care.
When all necessary bits are set as required, the pro-
gramming 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 14
. This method
does not require V
ID
. Refer to the Autoselect Com-
mand Sequence section for more information.
