Unlike EEPROM or NOR flash, FRAM writes at bus speed with no page-buffer or erase-before-write penalty — each byte write completes in the same cycle as a read, and endurance is effectively unlimited at 10^14 write cycles typical for the technology. ## Supply, temperature, and package — board-fit checklist Runs on a 3V to 3.6V rail — the narrow supply window means it pairs cleanly with 3.3V logic domains but won't tolerate a 5V I/O bus without a level translator. Housed in an 8-SOIC (3.90mm width) — the standard narrow-body SOIC footprint that pick-and-place handles without special nozzles, and the MSL rating for this package class is typically MSL-1 (no bake required before reflow). No pin-compatible drop-in replacement from Infineon is documented, so a BOM revision or second-source qualification may be needed for new builds.","metaTitle":"Infineon FM25CL64B-GATR F-RAM, 64Kbit, 16 MHz SPI, 8-SOIC","metaDescription":"Infineon FM25CL64B-GATR 64Kbit F-RAM, SPI interface, 16 MHz, 8-SOIC, -40 to +125°C.
