1. Description
The AT49BV320S(T) is a 2.7-volt 32-megabit Flash memory organized as 2,097,152
words of 16 bits each. The memory is divided into 71 sectors for erase operations.
The device is offered in a 64-ball CBGA package. The device has CE
signals to avoid any bus contention. This device can be read or reprogrammed using
a single power supply, making it ideally suited for in-system programming.
In some applications, in addition to the standard softlock sector protection mechanism, a requirement exists to allow for the permanent and irreversible locking of
selected region in the memory. The AT49BV320S(T) allows the user to permanently
lock eight regions, and once activated these secure regions cannot be altered or
erased through Software or Hardware at any time. Once activated, no facility exists to
over-ride the secure lock mechanism. The size of each secure region is 32K words,
and the location of these regions is determined by the Top or Bottom Boot Block designation. The location of the secure regions is shown on pages 3 - 4.
The secure regions can be locked in any sequence and at any time during normal
device operation. If all eight regions are permanently locked, then program and erase
operations in 1/8 of the memory will be disabled. Read operations can still be performed on any region that has the secure lock feature enabled. Full read and write
operations, standard sector operations including standard Sector locking can be performed on all regions that are not secure locked.

The AT49BV320S(T) device also contains a freeze feature that will freeze the lock status of the
secure regions. The freeze feature prevents any further locking of the secure regions. If the user
requires certain regions to be locked, then these regions must be programmed and locked prior
to activation of the freeze command. It is important to note that enabling the freeze feature is
irreversible.
