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.

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.
