CY62138FV30LL-45ZAXIT is a 2-Mbit (256 K × 8) CMOS asynchronous SRAM for battery-powered embedded systems. It runs from 2.2 V to 3.6 V over −40°C to +85°C and supports 45 ns access. Automatic power-down cuts standby to 1 µA typical (5 µA max) when CE is inactive, while active current is 1.6 mA typical at 1 MHz and 13 mA typical at fmax. It uses CMOS I/O levels and is offered in a Pb-free 32-pin STSOP.
