The CY15B256Q-SXET is a 256-Kbit (32K × 8) automotive-grade serial F-RAM memory, delivering nonvolatile storage with 10^13 read/write cycles and 121-year data retention at 85°C. It operates from 2.7 V to 3.6 V, supports SPI up to 33 MHz, and meets AEC-Q100 Grade 1 (–40°C to +125°C). Features include NoDelay™ writes, low 5 mA active current, 500 μA standby, 12 μA sleep mode, and robust hardware/software write protection.

Features

  • 256-Kbit nonvolatile F-RAM memory
  • 10^13 read/write cycle endurance
  • 121-year data retention at 85°C
  • NoDelay™ writes, instant at bus speed
  • Up to 33 MHz SPI interface
  • Supports SPI mode 0 and 3
  • Hardware and software write protection
  • Block protection for 1/4, 1/2, or full array
  • Device ID with manufacturer/product info
  • 5 mA active, 500 μA standby, 12 μA sleep
  • VDD range: 2.7 V to 3.6 V
  • Operating temp: –40°C to +125°C

Benefits

  • Reliable data even after 10^13 cycles
  • 121-year retention prevents data loss
  • Instant writes eliminate wait times
  • 33 MHz SPI enables fast data access
  • Drop-in replacement for flash/EEPROM
  • Flexible SPI mode compatibility
  • Robust write protection ensures safety
  • Block protection guards critical data
  • Device ID simplifies inventory tracking
  • Low power extends battery/system life
  • Wide voltage supports design flexibility
  • Operates in harsh environments
