The IDT70P249 is a very low power 4K x 16 Dual-Port Static RAM. The IDT70P249 is designed to be used as a stand-alone 64K-bit Dual-Port SRAM. This device provides two independent ports with separate control, address, and I/O pins that permit independent, asynchronous access for reads or writes to any location in memory. An automatic power down feature controlled by CS permits the on-chip circuitry of each port to enter a very low standby power mode.Fabricated using Renesas' CMOS high-performance technology, these devices typically operate on only 27mW of power.
