16-megabit (1M x 16) Secure 3-volt Only Memory AT49BV160S AT49BV160ST Summary (Complete Datasheet under NDA)

1. Description
The AT49BV160S(T) is a 2.7-volt 16-megabit Flash memory organized as 1,048,576 words of 16 bits each. The memory is divided into 39 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 mechanism, a requirement exists to allow for the permanent and irreversible locking of selected regions in the memory. The AT49BV160S(T) allows the user to permanently lock thirty-nine 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 the same as the sector size, and the location of these regions is determined by the Top or Bottom Boot Block designation. The locat
ion of the secure regions is shown on page 3. The secure regions can be locked in any sequence and at any time during normal device operation. 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 operations can be performed on all regions that are not secure locked.
