The CY15B256Q-SXA is a 256-Kbit (32K × 8) automotive serial F-RAM with SPI interface, providing nonvolatile memory with 100 trillion (1e14) read/write cycles and 151-year data retention at 65°C. It operates from 2.0 V to 3.6 V, supports up to 40 MHz clock, and features low active (2.5 mA), standby (150 μA), and sleep (8 μA) currents. The device offers advanced write protection, AEC-Q100 Automotive-A qualification, and is ideal for applications requiring frequent, fast writes.

Features

  • 256-Kbit F-RAM organized as 32K × 8
  • 100 trillion (10¹⁴) read/write cycles
  • 151-year data retention at 65°C
  • NoDelay™ writes, writes at bus speed
  • SPI interface up to 40 MHz
  • Supports SPI mode 0 and mode 3
  • Hardware and software write protection
  • Device ID for manufacturer and product
  • 2.5 mA active, 150 μA standby, 8 μA sleep
  • Low-voltage operation: VDD = 2.0 V to 3.6 V
  • Operating temp: –40°C to +85°C
  • Output/input pin capacitance: 8 pF/6 pF

Benefits

  • Enables fast, frequent data logging
  • Eliminates write delays for real-time storage
  • Reliable data retention for 151 years
  • Drop-in replacement for serial flash/EEPROM
  • Reduces system power consumption
  • Flexible operation across voltage range
  • Protects data with multiple security options
  • Simplifies device identification and tracking
  • Operates reliably in harsh environments
  • Supports high-speed SPI communication
  • Minimizes board space with small package
  • Low pin capacitance supports fast signals
