Overview
Fujitsu’s FM3 microcontroller family incorporates the ARM Cortex-M3 standard core. It is a scalable platform, ranging from low pin count, low power microcontrollers (MCUs) to high performance products with up to 1MB flash memory and a rich set of peripherals, including USB, CAN and Ethernet.
The MCUs are based on Fujitsu’s highly reliable (100,000 erase/write cycles) and high speed (0 wait states at 72MHz) embedded flash process. All MCUs are produced in Fujitsu’s own wafer fabs enabling control over quality, availability and costs.
The ARM Cortex M3 architecture extends the existing MCU lineup and fills the gap between Fujitsu’s 16-bit CISC and 32-bit RISC CPU cores. Both proprietary MCU families 16FX and FR will be continued and further developed.

Product Lineup
The Fujitsu FM3 family is split into 4 groups: High Performance, Basic, Low Power and Ultra Low Leakage. The main differences are CPU operation frequency and supply voltage. Beside this, all products are based on the same architecture (software compatible), use the same peripherals and are pin compatible in most cases. The ultra low leakage group products are based on an optimised low leakage process technology.
