CY621472E30LL-45ZSXI
CY621472E30LL-45ZSXI is a 4-Mbit (256K × 16) CMOS SRAM for battery-powered embedded systems. It operates from 2.2 V to 3.6 V over –40°C to +85°C and delivers a 45 ns access time. Typical active current is 3.5 mA at 1 MHz (6 mA max), while standby power-down current is 2.5 µA typical (7 µA max) when deselected. Dual chip enables and byte enables support easy expansion and 8-bit accesses.
