Infineon FRAM, 64 kB Memory Size, SPI Interface - CY15B064Q-SXET

This FRAM is a non-volatile memory device intended for systems requiring frequent writes and persistent data retention in automotive environments. It communicates over an SPI Interface and is supplied in an eight-pin SOIC package suitable for board-mounted implementations. The device operates from 3V to 3.6V and is designed to function across a wide temperature range for demanding applications.

Features and Benefits:

• 64 kB capacity enables large low-latency data logging
• 16MHz clock supports Rapid serial communication
• 8-bit data bus simplifies byte-oriented transfers
• -40 to 125°C rating maintains operation in harsh temperatures
• AEC-Q100 Grade 1 qualification suits automotive use cases

Applications

• Suitable for in-vehicle data-logging modules
• Ideal for microcontroller backup and state retention
• Used with sensor systems requiring frequent writes
• Can be used for calibration and configuration storage
• Suitable for control units exposed to high ambient temperatures

What supply voltage range does it require?
