CY14B256Q2-LHXI

CY14B256Q2-LHXI is a 256-Kbit (32K × 8) SPI nvSRAM that pairs SRAM with QuantumTrap nonvolatile cells to retain data without a battery. It supports 40-MHz SPI (modes 0 and 3), write protection via WP and software block protection, and software STORE/RECALL. AutoStore on power-down uses an external 61 µF to 180 µF VCAP capacitor. Operates from 2.7 V to 3.6 V over -40°C to 85°C in an 8-pin DFN package.
