The Infineon FM24CL64B-GTR is a 64 kbit F-RAM (ferroelectric RAM) non-volatile memory organized as 8K x 8 (8 kB) with an 8-bit word size, supplied in an 8-pin SOIC package on tape and reel. It uses a 2-wire I2C interface at up to 1 MHz, operates from 2.7 V to 3.65 V (3 V nominal) at 300 uA nominal supply current, and has a 3 us access time. FM24CL64B-GTR is an asynchronous, surface-mount device rated -40 C to +85 C, lead free and RoHS compliant.

F-RAM is a non-volatile memory that writes at essentially bus speed with no erase cycle and no write delay, and it offers vastly higher write endurance than EEPROM or flash, so it is chosen wherever data must be committed frequently or at the moment power is lost. The FM24CL64B-GTR is a direct pin-and-protocol alternative to a serial EEPROM in that role, used for high-frequency data logging, run-hour and cycle counters, tamper and event records, last-known-state retention, and metering registers. Its -40 C to +85 C range and low supply current suit utility meters, industrial controllers and drives, medical devices, printers and consumables, and automotive-adjacent electronics. Buyers are typically embedded designers replacing an EEPROM that is wearing out or losing writes on power-down.
