High-Density 256 Kbit Parallel SRAM for Industrial Applications with Wide Operating Range CY14E256LA-SZ25XI is a 256-Kbit (32 K × 8) parallel nvSRAM that combines fast SRAM with QuantumTrap nonvolatile storage. It operates from a single 4.5 V to 5.5 V supply with 25 ns access. Data is automatically STOREd on power-down using a 68 µF VCAP capacitor and RECALLed on power-up, with optional software or HSB pin control. It supports 1 million STORE cycles and 20-year retention over -40 to 85°C.
