Product Summary

The IDT71321SA-55JI is a high-speed 2K x 8 dual-port static RAM. The IDT71321SA-55JI is designed to be used as a stand-alone 8-bit Dual-Port RAM or as a“MASTER” Dual-Port RAM together with the IDT7142 “SLAVE”Dual-Port in 16-bit-or-more word width systems. Fabricated using IDT’s CMOS high-performance technology, the IDT71321SA-55JI typically operates on only 325mW of power. Low-power (LA) versions offer battery backup data retention capability, with each Dual-Port typically consuming 200µW from a 2V battery.
