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.","metaTitle":"Infineon CY15B064J-SXET 64Kbit I²C FRAM, AEC-Q100, 8-SOIC","metaDescription":"Infineon CY15B064J-SXET 64Kbit FRAM, I²C 1MHz, 3V-3.6V, -40°C to +125°C, AEC-Q100, 8-SOIC.
