The CY15B016J-SXAT is a 16-Kbit (2K × 8) automotive-grade serial F-RAM with I2C interface, operating from 2.7 V to 3.65 V and –40°C to +85°C. It offers 100 trillion read/write cycles, 151-year data retention, and NoDelay™ writes, surpassing EEPROM in endurance, speed, and power use. Supporting up to 1 MHz I2C, it is a hardware drop-in replacement for serial EEPROM in automotive and industrial data logging.
