Infineon FRAM, 256kB Memory Size, 32K x 8 bit Organisation - FM25W256-G

This FRAM is a non-volatile memory device designed for Serial Peripheral Interface environments, offering fast persistent storage for embedded systems. It operates across a broad supply range and is suitable for demanding electronic assemblies requiring compact surface-mount components and automotive-grade quality.

Features and Benefits:

• 20ns random access time enables rapid data retrieval in control loops
• 20MHz SPI operation supports high-throughput serial communication
• 256kB capacity provides ample persistent storage for logs
• 8-bit data bus simplifies microcontroller interfacing
• AEC‑Q100 qualification permits use in automotive electronic systems
• 2.7V to 5.5V supply range allows flexible power-rail integration

Applications

• Suitable for automotive control module non-volatile storage
• Ideal for industrial data-logging in harsh environments
• Used with microcontrollers requiring fast serial memory
• Can be used for configuration storage in networked devices
• Employed in sensor systems needing frequent writes

What package style should designers plan for on the PCB?

It is supplied in a surface-mount SOIC package with an 8-pin footprint suitable for automated placement.

How does the device handle temperature extremes in field installations?

The device is rated to operate between -40°C and 85°C, enabling use across typical industrial and vehicle ambient ranges.

How many addressable words and organisation does it provide?

Memory is organised as 32K words of 8 bits each, giving 32k addressable locations.

What pin count and bus width are presented for interface considerations?

The device uses an 8-pin package and presents an 8-bit data bus for straightforward parallel data grouping where applicable.
