AT52BR3224A(T)/3228A(T)
The 4-megabit SRAM is a high-speed, super low-power CMOS SRAM organized as 256K
words by 16 bits. The SRAM uses high-performance full CMOS process technology and is
designed for high-speed and low-power circuit technology. It is particularly well-suited for the
high-density low-power system application. This device has a data retention mode that guar-
antees data to remain valid at a minimum power supply voltage of 1.2V.
