The I²C interface runs at up to 1 MHz, and the 550 ns access time means a byte write completes in the same bus cycle as a read — no polling for write-complete, no page-write delay. ## Supply and temperature — industrial-grade, single 5 V rail Operates from 4.5 V to 5.5 V — a single 5 V ±10 % rail is sufficient, which matches legacy 5 V logic and many microcontroller power domains without an extra regulator. Rated for -40 °C to +85 °C ambient, covering industrial enclosures, outdoor telecom cabinets, and automotive cabin (non-engine-bay) applications. ## SOIC-8 footprint — drop-in for legacy EEPROM sockets Supplied in an 8-SOIC (3.90 mm width) package, surface-mount, with a 1.27 mm pitch that matches industry-standard EEPROM footprints — no board spin needed when migrating from a serial EEPROM to FRAM. Available in Tape & Reel or Cut Tape, so it fits both prototype hand-assembly and production pick-and-place runs.","metaTitle":"Infineon FM24C64B-GTR FRAM 64Kbit I²C 1MHz 8SOIC","metaDescription":"Infineon FM24C64B-GTR 64Kbit FRAM, I²C 1MHz, 8-SOIC, active production, RoHS3.
