CY14B256LA-ZS25XI is a 256-Kbit (32 K × 8) parallel nvSRAM combining fast SRAM with QuantumTrap nonvolatile storage. It runs 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 and recalled on power-up; STORE/RECALL can also be initiated by HSB pin or software. It is rated for 20-year data retention and 1 million nonvolatile STORE cycles.
