CY14E116N-Z30XIT is a 16-Mbit nvSRAM organized as 1024K × 16, combining SRAM with QuantumTrap nonvolatile storage. It runs from 4.5 V to 5.5 V over -40°C to 85°C and supports 30 ns access. Automatic STORE on power-down uses an external VCAP capacitor (19.8 µF to 82.0 µF), with RECALL on power-up or by software/HSB pin. It specifies 20-year data retention and 1 million STORE cycles.
