FM24CL04B in Cypress / Infineon FM24 & FM25 FRAM Family
The FM24CL04B is a family of 4-Kbit non-volatile ferroelectric RAM (F-RAM) manufactured by Infineon Technologies (formerly Cypress Semiconductor). Designed to replace standard EEPROM, these devices utilize a ferroelectric process that enables fast writes, high endurance of 100 trillion cycles, and low power consumption. They interface via a high-speed I2C bus, making them ideal for applications that require frequent or rapid data logging without the write-cycle delays or wear-out concerns associated with traditional floating-gate memory technologies.
Variants in This Sub-Family
Variants within the FM24CL04B family primarily differ in their packaging and delivery formats. The suffix -G denotes an 8-pin SOIC package, while the -GTR suffix indicates the same package supplied on Tape and Reel for automated assembly. Electrical specifications across the sub-family remain consistent, featuring a wide operating voltage range of 2.7V to 3.6V and an industrial temperature rating of -40 to +85 degrees Celsius.
