CY14B256LA-SZ45XIT

CY14B256LA-SZ45XIT is a 256-Kbit (32 K × 8) parallel nvSRAM that combines fast SRAM with QuantumTrap nonvolatile cells. It operates from 2.7 V to 3.6 V over -40°C to +85°C with 45 ns access. Data is automatically stored on power-down using a 61–180 µF VCAP capacitor, with up to 1 million STORE cycles and 20-year retention. STORE/RECALL are also controlled by software or the HSB pin.
