Persistent Sector Protection
The autoselect mode provides manufacturer and device identification, and sector group 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 VID on address pin A9. Address pins A6,
A3, A2, A1, and A0 must be as shown in
address must appear on the appropriate highest order address bits (see
on page 38
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
require V
The device features several levels of sector protection, which can disable both the program and erase
operations in certain sectors or sector groups:
A command sector protection method that replaces the old 12 V controlled protection method.
