CY14B104NA-BA45XIT

CY14B104NA-BA45XIT is a 4-Mbit nvSRAM organized as 256K × 16, combining fast SRAM with QuantumTrap nonvolatile storage. It operates from 2.7 V to 3.6 V over -40°C to 85°C and supports 45 ns access. Data is automatically STOREd on power-down using a 61 µF to 180 µF VCAP capacitor, with STORE/RECALL also via software or HSB pin. Rated for 1M STORE cycles and 20-year retention in a 48-ball FBGA.
