CY14B104NA-BA20XI is a 4-Mbit (256K × 16) parallel nvSRAM combining fast SRAM with QuantumTrap nonvolatile storage. It operates from a single 2.7 V to 3.6 V supply over −40°C to 85°C, with 20 ns access time. Data is automatically STORED on power-down using a small VCAP capacitor and RECALLED on power-up; STORE/RECALL can also be initiated by pin or software, enabling nonvolatile buffering for embedded data log and configuration.
