AT52BR3244(T)/3248(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 technol-
ogy 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 guarantees data to remain valid at a minimum power supply voltage
of 1.2V.
