The AT52BR3224(T) combines a 32-megabit Flash (2M x 16) and a 4-megabit SRAM
(organized as 256K x 16) in a stacked 66-ball CBGA package. The AT52BR3228(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 temperature range.

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.
