The device is shipped with all sectors unprotected. Optional Spansion programming services enable
programming and protecting sectors at the factory prior to shipping the device. Contact your local sales office
for details.
It is possible to determine whether a sector is protected or unprotected. See the
Table 10.9,
Secured Silicon
Sector Addresses
on page 39
for details.
11. Sector Protection
The PL127J, PL129J, PL064J, and PL032J features several levels of sector protection, which can disable
both the program and erase operations in certain sectors or sector groups:
11.1
Persistent Sector Protection
A command sector protection method that replaces the old 12 V controlled protection method.
11.2
Password Sector Protection
A highly sophisticated protection method that requires a password before changes to certain sectors or sector
groups are permitted
11.3
WP# Hardware Protection
A write protect pin that can prevent program or erase operations in sectors SA1-133, SA1-134, SA2-0 and
SA2-1.
The WP# Hardware Protection feature is always available, independent of the software managed protection
method chosen.
11.4
Selecting a Sector Protection Mode
All parts default to operate in the Persistent Sector Protection mode. The customer must then choose if the
Persistent or Password Protection method is most desirable. There are two one-time programmable non-
volatile bits that define which sector protection method will be used. If the Persistent Sector Protection
method is desired, programming the Persistent Sector Protection Mode Locking Bit permanently sets the
device to the Persistent Sector Protection mode. If the Password Sector Protection method is desired,
programming the Password Mode Locking Bit permanently sets the device to the Password Sector Protection
mode. It is not possible to switch between the two protection modes once a locking bit has been set. One of
the two modes must be selected when the device is first programmed. This prevents a program or virus from
later setting the Password Mode Locking Bit, which would cause an unexpected shift from the default
Persistent Sector Protection Mode into the Password Protection Mode.
The device is shipped with all sectors unprotected. Optional Spansion programming services enable
programming and protecting sectors at the factory prior to shipping the device. Contact your local sales office
for details.
It is possible to determine whether a sector is protected or unprotected. See
Autoselect Mode
