VERY LOW POWER 1.8V 8K/4K x 16 DUAL-PORT STATIC RAM
The IDT70P257/247 is a very low power 8K/4K x 16 Dual-Port Static RAM. The IDT70P257/247 is designed to be used as a stand-alone 128/64K-bit Dual-Port SRAM or as a combination MASTER/SLAVE DualPort SRAM for 32-bit-or-more word systems. Using the IDT MASTER/ SLAVE Dual-Port SRAM approach in 32-bit or wider memory system applications results in full-speed, error-free operation without the need for additional discrete logic. 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 CE permits the on-chip circuitry of each port ...

Fabricated using IDT’s CMOS high-performance technology, these devices typically operate on only 30.6mW of power. The IDT70P35/34L (IDT70P25/24L) is packaged in a plastic 100-pin Thin Quad Flatpack, a 100-pin fine pitch Ball Grid Array, and a 100-pin 0.5mm pitch fpBGA.
