FM25L16B in Cypress / Infineon FM24 & FM25 FRAM Family
The FM25L16B is a 16-Kbit non-volatile memory family from Infineon Technologies, utilizing advanced Ferroelectric Random Access Memory (F-RAM) technology. Designed as a high-reliability replacement for serial EEPROM, it offers virtually unlimited write endurance and high-speed write operations at bus speeds. This family is primarily used in industrial and automotive environments where frequent, fast, and power-efficient data logging is critical for system integrity and state retention during power loss events.
Variants in This Sub-Family
Variants within the FM25L16B sub-family primarily differ based on packaging options and temperature grading. The most common commercial variant is the 8-pin SOIC (G), often provided in tape-and-reel (GTR) format for automated assembly. Some specific part numbers may also denote specialized qualifications, such as automotive-grade AEC-Q100 compliance, though the core memory architecture and 20 MHz SPI timing remains consistent across the standard sub-family lineup.
