Datasheet FM25L04B-GTR

Infineon FRAM, 4kB Memory Size, 3.6V Maximum Supply Voltage - FM25L04B-GTR

This FRAM is a non-volatile memory device designed for serial data storage and fast read/write access in embedded systems. It operates from a low-voltage supply and communicates over an SPI interface, making it suitable for compact surface‑mount digital designs where frequent, high‑speed memory transactions are required. The component meets automotive AEC‑Q100 criteria for use in vehicle electronics.

Features and Benefits:

• 20 ns maximum random access time enables rapid data retrieval
• 20 MHz maximum clock frequency supports high‑speed serial transfers
• 2.7-3.6V operating range reduces supply design complexity
• 8‑bit data bus width simplifies microcontroller interfacing
• -40 to 85 °C operating range allows use in varied environments
• AEC‑Q100 automotive rating supports rigorous application standards

Applications

• Suitable for automotive sensor data‑logging modules
• Ideal for low‑power embedded control units
• Used with microcontrollers requiring serial non‑volatile memory
• Can be used for configuration storage in industrial electronics
• Appropriate for telemetry and logging equipment in vehicles

What package style should I plan for on the PCB?

The device comes in an SOIC surface‑mount package with an 8‑pin footprint for standard assembly processes.

How is memory organised for addressing and transfers?

Memory is organised as a 512Mx8‑bit array, presenting 8‑bit words over the serial interface for straightforward addressing and block transfers.

What pin count and bus width does it require?

The package uses eight pins and operates on an 8‑bit data bus for parallel word organisation internally while communicating via SPI.

Are there limits on ambient temperature during operation?

The device is specified to operate between -40 °C and 85 °C, covering typical automotive and industrial ambient conditions.
