CY14E256LA-SZ45XI is a 256-Kbit (32 K × 8) parallel nvSRAM combining fast SRAM with QuantumTrap nonvolatile storage per cell. It runs from a single 4.5 V to 5.5 V supply over −40°C to +85°C and supports 45 ns access. Data is automatically stored on power-down using a 61 µF to 180 µF VCAP capacitor, with software- or pin-initiated STORE/RECALL, 1M STORE cycles, and 20-year retention.
