CY14B104LA-ZS20XIT is a 4-Mbit (512K × 8) 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. AutoStore saves SRAM to nonvolatile cells on power-down using a 61 µF to 180 µF VCAP capacitor; data is RECALLed on power-up, with software- or pin-initiated STORE/RECALL control.
