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.
