32-megabit (2M x 16) Secure 3-volt Only Memory AT49BV320S AT49BV320ST Summary (Complete Datasheet under NDA)
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 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.
NOTE: This is a summary document. The complete document is available under NDA. For more information, please contact your local Atmel sales office.
3532AS-FLASH-9/06
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.
