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 and OE control

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 mecha-

nism, 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 des-

ignation. 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 per-

formed on any region that has the secure lock feature enabled. Full read and write

operations, standard sector operations including standard Sector locking can be per-

formed on all regions that are not secure locked.

AT49BV320S(T) Summary

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.
