The CY62146EV30LL-45BVXIT is a 4-Mbit (256K × 16) CMOS SRAM for battery-powered systems, offering 45 ns access with a 2.2 V to 3.6 V supply over −40°C to +85°C. It supports automatic power-down when CE is inactive, with 2.5 µA typical (7 µA max) standby at VCC = 3.6 V, and 3.5 mA typical active current at 1 MHz. Byte enables (BHE/BLE) support 8-bit writes and reads. 48-ball Pb-free VFBGA.
