FM24C16B in Cypress / Infineon FM24 & FM25 FRAM Family
The FM24C16B family, manufactured by Infineon Technologies (formerly Cypress Semiconductor), consists of high-performance 16-Kbit ferroelectric random access memory (FRAM) ICs that utilize an I2C interface. These devices are designed to replace traditional EEPROM and SRAM in systems requiring high endurance and low power consumption. Unlike EEPROM, the FM24C16B performs write operations at bus speed without internal delays, ensuring data integrity during sudden power loss and eliminating the need for wear-leveling algorithms in data logging applications.
Variants in This Sub-Family
Variants within the FM24C16B family primarily differ in their package types and temperature ratings to suit various assembly requirements. The most common variant is the FM24C16B-G, housed in an 8-pin SOIC package, while the GTR suffix indicates a tape-and-reel shipping format for automated pick-and-place assembly. Engineers should also note that some iterations provide different operating temperature ranges, such as industrial Grade 1 or Grade 3, to meet specific environmental demands.
