Autoselect
The Autoselect mode provides manufacturer ID, Device identification, and sector protection information,
through identifier codes output from the internal register (separate from the memory array) on DQ7-DQ0. This
mode is primarily intended for programming equipment to automatically match a device to be programmed
with its corresponding programming algorithm (see
in-system.
There are two methods to access autoselect codes. One uses the autoselect command, the other applies V
on address pin A9.
When using programming equipment, the autoselect mode requires V
Address pins must be as shown in
To access Autoselect mode without using high voltage on A9, the host system must issue the Autoselect
command.
The Autoselect command sequence may be written to an address within a sector that is either in the read
or erase-suspend-read mode.
The Autoselect command may not be written while the device is actively programming or erasing.
The system must write the reset command to return to the read mode (or erase-suspend-read mode if the
sector was previously in Erase Suspend).
It is recommended that A9 apply V
that A9 apply from V
See
When verifying sector protection, the sector address must appear on the appropriate highest order address
bits (see
been set as required, the programming equipment may then read the corresponding identifier code on
DQ15-DQ0. The Autoselect codes can also be accessed in-system through the command register.
