CY14B256LA-SP25XIT is a 256-Kbit (32 K × 8) parallel nvSRAM combining fast SRAM with QuantumTrap nonvolatile storage. It operates from 2.7 V to 3.6 V over −40°C to 85°C and supports 25 ns access. Data is automatically stored on power-down using a 61 µF to 180 µF VCAP capacitor, with STORE and RECALL also pin or software controlled. Rated for 1 million STORE cycles and 20-year retention.
