AEC-Q100 FRAM for under-hood data logging
The CY15B064J-SXET: This temperature range covers the engine-bay thermal profile, so the memory retains calibration data and fault logs through a hot soak without a backup battery.
FRAM write endurance and instant non-volatility
The 1 MHz clock rate means a random byte write completes in under 1 µs, making it suitable for real-time parameter storage in an ECU that logs sensor data every millisecond. Supply voltage spans 3V to 3.6V, which aligns to a standard 3.3V rail — no additional regulator is required when the MCU already runs at 3.3V.
8-SOIC package and board integration
Surface-mount assembly with tape-and-reel (TR) or cut-tape (CT) options suits both prototype runs and high-volume reflow. The operating temperature range demands no special thermal management beyond standard PCB copper pour.
