Addresses for Protection/Unprotection
Sector/Sector Block Protection and Un-
protection
The hardware sector protection feature disables both
programming and erase operations in any sector. The
hardware sector unprotection feature re-enables both
program and erase operations in previously protected
sectors. Sector protection/unprotection can be imple-
mented via two methods.
(Note: For the following discussion, the term “sector”
applies to both sectors and sector blocks. A sector
block consists of two or more adjacent sectors that are
protected or unprotected at the same time (see
Table 4,
“Am29BDS128H Boot Sector/Sector Block Addresses
for Protection/Unprotection,” on page 16
Sector Protection
The Am29BDSxxxH family features several levels of
sector protection, which can disable both the program
and erase operations in certain sectors or sector
groups:
Persistent Sector Protection
A command sector protection method that replaces
the old 12 V controlled protection method.
Password Sector Protection
A highly sophisticated protection method that requires
a password before changes to certain sectors or sec-
tor groups are permitted
WP# Hardware Protection
A write protect pin that can prevent program or erase
operations in the outermost sectors.
The WP# Hardware Protection feature is always avail-
able, independent of the software managed protection
method chosen.
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 customer decides to con-
tinue using the Persistent Sector Protection method,
they must set the
