CY14B256PA-SFXIT is a 256-Kbit (32 K × 8) SPI nvSRAM with integrated real-time clock. It stores SRAM data to QuantumTrap nonvolatile elements automatically on power-down (AutoStore) and restores on power-up, with software or HSB pin control. Operates from 2.7 V to 3.6 V over -40°C to 85°C, uses a 16-pin SOIC, and supports 40 MHz SPI with 20-year retention and 1M STORE cycles for nonvolatile logging.

Features

  • 256-Kbit nvSRAM, 32 K x 8
  • AutoStore on power-down
  • STORE via SPI or HSB pin
  • Power-up RECALL to SRAM
  • 40 MHz SPI read/write
  • 104 MHz fast read instructions
  • SPI mode 0 and mode 3
  • 8-byte serial number
  • Manufacturer and product ID
  • WP pin and block write protection
  • RTC alarm, watchdog, INT/SQW
  • Sleep mode current 8 µA max

Benefits

  • Keeps data with no firmware saves
  • AutoStore secures data on power loss
  • Choice of SPI or pin STORE control
  • RECALL restores state after reset
  • 40 MHz SPI reduces access latency
  • 104 MHz fast reads raise throughput
  • Mode 0/3 simplifies MCU interface
  • Serial number supports traceability
  • ID read enables auto configuration
  • Write protection avoids corruption
  • RTC functions reduce BOM count
  • 8 µA sleep cuts standby drain
