CY62157EV30LL-55ZSXE is an 8-Mbit (512K × 16) CMOS low-power SRAM for automotive designs, with 55 ns access time. It operates from 2.2 V to 3.6 V over –40°C to +125°C (Automotive-E). Typical standby current is 2 µA with automatic power-down, and typical active current is 1.8 mA at 1 MHz. It supports byte writes via BHE/BLE and uses CE1/CE2/OE for standby and easy memory expansion.
