CY62157G30-45ZSXAT is an AEC-Q100 qualified 8-Mbit (512K × 16) asynchronous SRAM with embedded ECC for single-bit error correction. It operates from 2.2 V to 3.6 V (3 V typical) over –40°C to +85°C, uses dual chip-enable with BLE/BHE byte control, and supports 45 ns access. Automatic power-down standby is 1.4 µA typical (6.5 µA max), and data retention is specified down to 1.0 V.
