CY14E256Q - 256-Kbit (32 K x 8) SPI nvSRAM

Download the CY14E256Q datasheet PDF. This datasheet also covers the CY14C256Q variant, as both devices belong to the same 256-kbit (32 k x 8) spi nvsram family and are provided as variant models within a single manufacturer datasheet.

Key Features

  • 256-Kbit nonvolatile static random access memory (nvSRAM) internally organized as 32 K × 8.
  • STORE to QuantumTrap nonvolatile elements initiated automatically on power-down (AutoStore) or by using SPI instruction (Software STORE) or HSB pin (Hardware STORE).
  • RECALL to SRAM initiated on power-up (Power-Up RECALL) or by SPI instruction (Software RECALL).
  • Support automatic STORE on power-down with a small capacitor (except for CY14X256Q1A).
  • High reliability.
  • Infinite.
