CY621472E30LL-45ZSXIT is a 4-Mbit (256K × 16) CMOS SRAM in a 44-pin TSOP II (Pb-free) package for 3 V-typ systems. It operates from 2.2 V to 3.6 V over –40°C to +85°C and supports 45 ns access. Typical active current is 3.5 mA at 1 MHz, with automatic power-down standby at 2.5 µA typical (7 µA max) when deselected. Dual chip enables and byte enables simplify expansion and byte-wide reads/writes.
