About

Outstanding performance

The FM3 portfolio unleashes your product design with a wide range of product options offering operating frequencies up to 144 MHz, 1.65 V to 5.5 V operating voltage, and up to 1.5 MB flash and 192 KB RAM. The fast flash combined with a flash accelerator circuit (pre-fetch buffer plus instruction cache) provides zero-wait-state operation up to 144 MHz.

Robustness

5.5 V power supply capability maximizes noise immunity for industrial and motor control applications. The internal, trimmed RC oscillators function as an independent clock source for the clock supervisor and watchdog modules. The devices also feature a two-stage programmable low voltage detector (LVD), a CRC hardware module, a memory protection unit (MPU), and programmable emergency stop input for inverter motor control.

Advanced peripherals

Peripheral features include multiple motor-control timers, high-speed 12-bit ADCs, and a variety of communication interfaces. Available packages, which range from 32 to 176 pins, include LQFP, QFN, and BGA types.
