FM25VN10 in Cypress / Infineon FM24 & FM25 FRAM Family
The FM25VN10 family by Infineon Technologies (formerly Cypress Semiconductor) consists of high-performance 1Mbit serial non-volatile ferroelectric RAM (FRAM) utilizing the SPI interface. Unlike traditional Flash or EEPROM, these components offer virtually unlimited write endurance and high-speed write capabilities at bus speed without soak times. They are designed for mission-critical systems requiring frequent, reliable data logging and high-speed non-volatile storage in demanding industrial and automotive environments.
Variants in This Sub-Family
Variants within the FM25VN10 sub-family primarily differ by their packaging and temperature qualification. The standard G-suffix denotes an 8-pin SOIC package, but options exist for varying industrial or automotive-grade temperature ratings. Some versions may also feature a unique 64-bit ID or differing voltage tolerances, ensuring compatibility with both legacy 3.3V systems and modern low-voltage logic families across specialized industrial use cases.
