The CY15B128J-SXET is a 128-Kbit (16K × 8) automotive serial F-RAM with I2C interface, offering 100 trillion (10¹⁴) read/write cycles and 151-year data retention at 65°C. It operates from 2.0 V to 3.6 V, supports -40°C to +85°C, and features NoDelay™ bus-speed writes, 175 μA active current at 100 kHz, and 8 μA sleep mode. Housed in an 8-pin SOIC, it enables reliable, low-power, and frequent-write data storage for automotive and industrial applications.

Features

  • 128-Kbit F-RAM organized as 16K × 8
  • 100 trillion (10¹⁴) read/write endurance
  • 151-year data retention at 65°C
  • NoDelay™ writes, RAM-like speed
  • Fast I2C interface up to 3.4 MHz
  • Low active current: 175 μA at 100 kHz
  • 8 μA sleep mode current
  • Wide VDD: 2.0 V to 3.6 V
  • Operating temp: –40°C to +85°C
  • Device and manufacturer ID
  • Direct hardware replacement for EEPROM
  • Supports legacy I2C timings (100/400 kHz)

Benefits

  • Enables frequent, instant data logging
  • Eliminates write delays, boosts system speed
  • 10¹⁴ cycles for maintenance-free operation
  • 151-year retention prevents data loss
  • Reduces power in active and sleep modes
  • Wide VDD simplifies power design
  • Operates reliably from –40°C to +85°C
  • Drop-in replacement for serial EEPROM
  • Supports legacy and new I2C designs
  • Device ID enables easy inventory tracking
  • No data polling needed after writes
  • Low power extends battery/system life
