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 mecha-

nism, 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 opera-

tions including standard Sector locking operations can be performed on all regions

that are not secure locked.

NOTE: This is a summary document.

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.
