Infineon 256 kB FRAM 8-Pin SOIC

Infineon FRAM, 256kB Memory Size, 3.6V Maximum Supply Voltage - FM24V02A-G

This FRAM is a non-volatile memory device designed for embedded and automotive environments, offering persistent data storage with low-voltage operation. It functions as byte-addressable memory in a compact surface-mount package and is suitable for systems needing frequent writes and long data retention across power cycles. The device operates across a wide temperature span for demanding industrial or vehicular installations.

Features and Benefits:

• 256kB capacity provides substantial onboard data retention
  Random access time 450ns enables quick read/write responsiveness
  Clock rate up to 3.4MHz supports high-speed serial transfers
  Operates from 2V to 3.6V for low-voltage system compatibility
  Organised as 32Kx8 for straightforward byte-oriented interfacing
  Meets AEC‑Q100, enabling automotive-grade component selection

Applications

• Suitable for automotive control-module parameter storage
  Ideal for instrument clusters and ECU data logging
  Used with industrial controllers in harsh temperatures
  Can be used for frequent-logging sensor data buffers
  Used for boot-code storage in low-voltage systems

What package and mounting style does it use?

The device is supplied in an 8-pin SOIC package intended for surface-mount assembly.

What pin and data-bus configuration should designers expect?

It presents an 8-bit data bus across 8 pins allowing standard parallel byte transfers via the serial-interface mapping used in system designs.

What environmental limits must be considered for deployment?

The component is rated to function between -40°C and 85°C, suitable for industrial and many automotive ambient ranges.

How compact is the device for board-level placement?

The package measures 4.97mm in length and 3.98mm in width with a height of 1.38mm, permitting dense PCB layouts.
