CY62146EV30LL-45ZSXIT is a 4-Mbit (256K × 16) CMOS static RAM for 3 V systems, specified for 45 ns access. It operates from 2.2 V to 3.6 V over –40°C to +85°C. Low-power modes include automatic CE power-down (2.5 µA typ, 7 µA max) and 3.5 mA typ active current at 1 MHz (20 mA max at fmax). Byte writes use BLE/BHE, with tri-stated I/Os when deselected, in a 44-pin Pb-free TSOP II.
