Infineon 4 kB SPI FRAM 8-Pin SOIC, FM25L04B-G

This FRAM is a non-volatile memory device that provides small-capacity, high-speed serial storage for embedded systems. It operates across a low-voltage supply range and communicates via an SPI interface, offering Rapid read/write access in applications where endurance and speed are required. The device is supplied in a Compact SOIC package suitable for PCB mounting and conforms to RoHS restrictions.

• 20MHz clock delivers fast serial transfer rates
• 2.7V minimum supply enables low-voltage operation
• 3.6V maximum supply supports safe voltage headroom
• 8-bit data bus permits byte-wise data transactions
• -40°C to 85°C range suits extended temperature use

• Suitable for non-volatile parameter storage in controllers
• Ideal for data logging in temperature-variable environments
• Used for firmware scratchpad in SPI-based designs
• Can be used for small lookup tables in industrial equipment
• Used with microcontrollers requiring Compact external memory

The memory is arranged as 512 x 8-bit words, providing 4 kB total capacity.

It is provided in an SOIC package with an 8-pin count for through-solder placement.

The package meets Restriction of Hazardous Substances (RoHS) approval requirements.

Communication is performed over an SPI serial Interface supporting standard SPI signalling.
