CY62147EV18LL-55BVXI is a 4-Mbit (256 K × 16) CMOS static RAM for low-power portable systems. It operates from 1.65 V to 2.25 V over -40°C to +85°C and provides 55 ns access. At VCC = 2.25 V, ICC is 15 mA typ (20 mA max) at fmax and 2 mA typ at 1 MHz. Automatic power-down cuts standby to 1 µA typ (7 µA max) when deselected. Byte enables (BLE/BHE) support x8 access. It is offered in a Pb-free 48-ball VFBGA.
