The CY15B256J-SXAT is a 256-Kbit (32K × 8) automotive serial F-RAM with I2C interface, delivering nonvolatile data storage with 100 trillion read/write cycles and 151-year retention at 65°C. It supports NoDelay™ writes at bus speed, operates from 2.0 V to 3.6 V over –40°C to +85°C, and achieves up to 3.4 MHz I2C.

Features

  • 256-Kbit nonvolatile F-RAM, 32K x 8
  • 151-year data retention at 65°C
  • 100 trillion (10¹⁴) read/write cycles
  • NoDelay™ writes, immediate data storage
  • I2C interface up to 3.4 MHz
  • Supports 100 kHz, 400 kHz, and 1 MHz modes
  • Low power: 175 μA active, 8 μA sleep
  • VDD operation: 2.0 V to 3.6 V
  • Write protection via WP pin
  • Schmitt trigger inputs for noise immunity
  • Device ID with manufacturer and product info
  • Input/output capacitance: max 8 pF

Benefits

  • Reliable data storage for 151 years
  • Withstands 100 trillion write cycles
  • Instant writes eliminate wait times
  • Fast I2C enables rapid data transfer
  • Drop-in replacement for serial EEPROM
  • Low power extends battery life
  • Operates from 2.0 V to 3.6 V supply
  • Write protection prevents accidental changes
  • Noise immunity ensures robust operation
  • Device ID simplifies inventory tracking
  • Low capacitance supports high-speed bus
  • Flexible timing for legacy and new designs
