Overview for F28M3x MCUs


F28M3x dual-subsystem microcontrollers enable connectivity without compromise

The F28M3x series of microcontrollers brings together connectivity and control by combining an ARM Cortex-M3™ core with the C28x core on to one device. With F28M3x, applications such as solar inverters and industrial control can keep the benefits of separating the communication and control portions while maintaining a single-chip solution. In addition, F28M3x microcontrollers enable safety certifications in your system via enhanced hardware and safety features.
