CY62147EV30LL-45ZSXI is a 4-Mbit (256K × 16) CMOS SRAM with 45 ns access for portable and embedded designs needing fast random access memory. It operates from 2.2 V to 3.6 V over -40°C to +85°C. Automatic power-down when deselected cuts standby to typ 2.5 µA (max 7 µA). Active current is typ 3.5 mA at 1 MHz, and the 16-bit I/Os support byte enables (BLE/BHE). Pb-free 44-pin TSOP II.
