71256L70DB - Renesas Electronics

Description: The 71256 5V CMOS SRAM is organized as 32K x 8. The circuit also offers a reduced power standby mode for significant system level power and cooling savings. The low-power (L) version also offers a battery backup data retention capability allowing operation off a 2V battery. Fully static asynchronous circuitry is used; no clocks or refreshes are required for operation. Military grade product is available.
