CY14E256Q5A-SXQ is a 256-Kbit (32 K × 8) SPI nvSRAM combining SRAM with QuantumTrap nonvolatile storage to retain data through power loss. It supports 40 MHz reads/writes with zero-cycle delay, AutoStore on power-down and RECALL on power-up, plus software STORE/RECALL. Operates from 4.5 V to 5.5 V over –40°C to +105°C in an 8-pin SOIC with VCAP (42 uF to 180 uF) and 8-byte serial number.

Features

  • 256-Kbit nvSRAM (32 K × 8)
  • AutoStore on power-down
  • SPI STORE and RECALL instructions
  • Power-up RECALL restores SRAM
  • 40 MHz SPI, zero cycle delay
  • SPI modes 0 and 3 supported
  • Write Disable (WRDI) protection
  • Block protect 1/4, 1/2, all
  • 8-byte serial number via SPI
  • Manufacturer ID and Product ID
  • 20 uA sleep current (IZZ)
  • VCC standby current 250 uA (ISB)

Benefits

  • Keeps data after power loss
  • Captures last state on power-down
  • Firmware-controlled backup/restore
  • Instant data restore at startup
  • Fast reads/writes with no wait
  • Easy MCU SPI integration
  • Prevents accidental writes
  • Protects critical data regions
  • Built-in traceability ID
  • Simplifies device identification
  • Extends battery life in sleep
  • Cuts idle power in standby
