Infineon 4 kB FRAM 8-Pin SOIC, FM24CL04B-GTR

This FRAM is a non-volatile memory device designed for low-power data storage in embedded and automotive systems. It operates within a typical single-supply range and provides byte-wide data access for firmware, calibration tables and logging tasks in space-constrained surface-mount designs. The component meets automotive stress requirements and is suitable for use across a broad industrial temperature range.

• 8-bit data bus enabling simple byte-wise interfacing and firmware updates
• 1MHz clock supporting timely serial access for control systems
• 550ns maximum random access time reducing read latency in real-time tasks
• Operates from 2.7V to 3.65V providing compatibility with common supply rails
• AEC‑Q100 qualification permitting deployment in automotive electronic modules
• Surface-mount SOIC package allowing automated assembly on compact PCBs

• Suitable for automotive CAN node parameter storage
• Ideal for instrumentation requiring frequent non-volatile writes
• Used with microcontroller systems for calibration data retention
• Can be used for event logging in industrial control equipment
• Used for low-power battery-backed data buffering in sensors

The device functions across a minimum supply of 2.7V up to a maximum of 3.65V, allowing designers to select regulators and supervision thresholds that maintain reliable operation within that window.

It is specified to operate between -40°C and 85°C, ensuring predictable electrical behaviour for applications spanning industrial to automotive thermal environments.

The package is a surface-mounted SOIC with a pin count of 8, so footprint clearance and solder fillet control should follow standard SOIC assembly practices to maintain mechanical and thermal integrity.

Memory is organised as 512M words by 8 bits, providing a total count of addressable 8-bit locations appropriate for compact non-volatile storage needs.
