FM25CL64B in Cypress / Infineon FM24 & FM25 FRAM Family
The FM25CL64B is a 64-kilobit non-volatile memory family from Infineon Technologies (formerly Cypress Semiconductor) based on ferroelectric RAM technology. Utilizing an industry-standard Serial Peripheral Interface, these devices serve as reliable alternatives to EEPROM and Flash. They are specifically engineered for applications requiring high-frequency write operations and long-term data integrity, as FRAM provides virtually instantaneous writes with endurance levels far exceeding traditional floating-gate memory architectures in industrial and automotive environments.
Variants in This Sub-Family
Variants within the FM25CL64B sub-family are primarily distinguished by their packaging options and temperature ratings. Common configurations include the 8-pin SOIC and the thermally enhanced 8-pin DFN (4x4.5mm) packages. Additionally, parts are screened for different thermal grades, including standard industrial (-40°C to +85°C) and automotive-compliant Grade 3 ranges, ensuring reliable operation in harsh environmental conditions while maintaining the same 2.7V to 3.6V operating voltage.
