Surface-mount, so it reflows with the rest of the board — no socket needed unless you plan field swaps. The 8-pin SOIC footprint is common; layout matches many serial EEPROMs and FRAMs, so a board designed for a 256Kbit SPI EEPROM can often take this part with a firmware change only.","metaTitle":"FM25W256-G F-RAM 256Kbit SPI 20MHz 8-SOIC, 2.7V-5.5V","metaDescription":"FM25W256-G active F-RAM, 256Kbit SPI non-volatile memory, 20 MHz clock, 2.7V–5.5V supply, -40°C to +85°C, ROHS3.

If you need a higher-density sibling, the FM25V20A-G offers 2Mbit at 40 MHz but requires a 2.0V supply minimum.
