The Infineon Technologies FM31L278-GTR is a highly integrated processor companion IC designed for processor-based systems. It incorporates 256 Kbit of ferroelectric random access memory (F-RAM) with a high endurance of 100 trillion read/writes and 151-year data retention. The device features a fast 2-wire serial interface (I2C) supporting up to 1 MHz frequency.
Key functionalities include a real-time clock/calendar, low voltage reset, watchdog timer, and early power-fail warning. It operates over an industrial temperature range of -40 °C to +85 °C with a supply voltage of 2.7 V to 3.6 V. The FM31L278-GTR consumes low power, with an active current of 1.5 mA at 1 MHz and a standby current of 120 µA.
This component is supplied in a 14-pin SOIC package suitable for surface mounting. Its high integration replaces multiple discrete parts, simplifying system design. The device is RoHS3 compliant and meets MSL 1 standards.
