CY62137FV18LL-55BVXI is a 2-Mbit (128K × 16) CMOS asynchronous SRAM 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. Active current is 1.6 mA typ at 1 MHz (2.5 mA max) and 13 mA typ at fmax (18 mA max). Automatic power-down cuts standby to 1 µA typ (5 µA max) when deselected, and a byte enable supports ×8/×16 operation. Pb-free 48-ball VFBGA.
