32-Bit Microcontroller

MCF521XX

Featuring a wide variety of serial interface offerings (up to three universal asynchronous receiver/transmitters (UARTS), one serial peripheral interface (SPI) and two I²C) the MCF521xx family allows developing for power-sensitive, high-performance applications where connectivity and easy integration to various systems is key.

The MCF521xx family is based on the cost-effective, low-power ColdFire® V2 core (up to 80 MHz and 76 MIPS performance @ 3.3-volt CPU). If more connectivity is needed, the MCF5221x Family offers USB on-the-go module
