It is part of the Automotive, AEC-Q100 series, meaning it is qualified for automotive-grade reliability and operates across -40°C to 125°C. The non-volatile storage combines the write endurance of RAM (essentially unlimited) with the data retention of EEPROM, making it a drop-in for parameter logging, calibration tables, and fault-recording buffers in engine ECUs, transmission controllers, and ADAS sensor modules. Supply range is 3V to 3.6V, matching common 3.3V rail designs. ## Lifecycle and compliance No last-time-buy or NRND notice applies. It is ROHS3 compliant. The AEC-Q100 qualification is factory-documented; no separate screening or lot acceptance is needed for automotive PPAP submissions. The package is 8-SOIC (3.90 mm body width), surface-mount, shipped in tube.","metaTitle":"CY15B064J-SXE 64Kbit FRAM, I²C, 1 MHz, AEC-Q100","metaDescription":"Infineon CY15B064J-SXE 64Kbit FRAM, I²C interface at 1 MHz, AEC-Q100 automotive grade, -40 to 125°C, 8-SOIC.

The FRAM technology offers essentially unlimited write endurance versus the ~1 million cycles of EEPROM, and writes at bus speed without the write-cycle delay. The supply range (3V to 3.6V) and I²C interface are compatible.
