AT52BR1672(T)/1674(T)

Description

Block Diagram

The AT52BR1672(T) combines a 16-megabit Flash (1M x 16) and a 2-megabit SRAM (orga-

nized as 128K x 16) in a stacked CBGA package; while the AT52BR1674(T) combines a 16-

megabit Flash (1M x 16) and a 4-megabit SRAM (organized as 256K x 16) in a stacked CBGA

package. Both devices operate at 2.7V to 3.3V in the industrial temperature range. The mod-

ules use a 16-megabit Flash with dual plane architecture for concurrent read/write operations.

The Flash is organized as 12M + 4M for planes B and A, respectively.

DATA

*NOTICE:

Stresses beyond those listed under “Absolute

Maximum Ratings” may cause permanent dam-

age to the device. This is a stress rating only and

functional operation of the device at these or any

other conditions beyond those indicated in the

operational sections of this specification is not

implied. Exposure to absolute maximum rating

conditions for extended periods may affect

device reliability.
