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.

Summary
(Complete
Datasheet
under NDA)
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 location 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.
NOTE: This is a summary document.
The complete document is available
under NDA. For more information,
please contact your local Atmel sales
office.
3560AS–FLASH–9/06
The AT49BV160S(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.
