AT52BR3224A(T)/3228A(T)

3338B–STKD–6/03

Block Diagram

Description

The AT52BR3224A(T) combines a 32-megabit Flash (2M x 16) and a 4-megabit SRAM (orga-

nized as 256K x 16) in a stacked 66-ball CBGA package. The AT52BR3228A(T) combines a

32-megabit Flash (2M x 16) and an 8-megabit SRAM (organized as 512K x 16) in a stacked

66-ball CBGA package. The stacked modules operate at 2.7V to 3.3V in the industrial temper-

ature range.
