Description
Autoselect Mode
Sector Group Protection/Unprotection
IL;
H = Logic High = V
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 V
Address pins A6 and A3–A0 must be as shown in
protection, the sector address must appear on the appropriate highest order address bits (see
on page 19
all necessary bits have been 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
Definitions on page 30
The hardware sector group protection feature disables both program and erase operations in any sector
group (see
re-enables both program and erase operations in previously protected sector groups. Sector group
protection/unprotection can be implemented via two methods.
Sector protection/unprotection requires VID on the RESET# pin only, and can be implemented either in-
system or via programming equipment.

sector group unprotect, all unprotected sector groups must first be protected prior to the first sector group
unprotect write cycle.
The device is shipped with all sector groups unprotected. Spansion offers the option of programming and
protecting sector groups at its factory prior to shipping the device through Spansion Programming Service.
Contact a Spansion representative for details.
It is possible to determine whether a sector group is protected or unprotected. See
