CY62157G30-45BVXAT 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 over –40°C to +85°C and supports 45 ns access. Typical standby current is 5 µA (35 µA max), with automatic power-down at 1.4 µA typ (6.5 µA max). Dual chip-enable and BHE/BLE byte enables support 8-/16-bit access in automotive ECUs.
