The CY14V104LA-BA25XIT is a 4-Mbit nvSRAM organized as 512 K × 8, combining fast SRAM with QuantumTrap nonvolatile storage. It supports hands-off AutoStore on power-down using a 61 µF to 180 µF VCAP capacitor, and software or HSB-pin STORE/RECALL control. Core VCC is 3.0 V to 3.6 V with 1.65 V to 1.95 V VCCQ I/O, 25 ns access, 1M STORE cycles, 20-year retention, in a 48-ball FBGA.
