CY14V101QS-SF108XQ is a 1-Mbit (128K × 8) Quad SPI nvSRAM that combines SRAM with SONOS nonvolatile cells for batteryless data retention. It supports SPI/DPI/QPI up to 108 MHz for read and write bandwidth up to 54 MBps, with AutoStore on power-down and RECALL on power-up, plus HSB hardware STORE. The nonvolatile array is rated for 20-year retention at 85°C. Operates from 2.7 V to 3.6 V core and 1.71 V to 2.0 V I/O over –40°C to 105°C.
