C2000™ 32-bit microcontrollers are optimized for processing, sensing, and actuation to improve closed-loop 

performance in real-time control applications such as industrial motor drives; solar inverters and digital power; 

electrical vehicles and transportation; motor control; and sensing and signal processing. The C2000 line includes 

the Premium performance MCUs and the Entry performance MCUs.

The F2806x family of microcontrollers (MCUs) provides the power of the C28x core and CLA coupled with highly 

integrated control peripherals in low pin-count devices. This family is code-compatible with previous C28x-based 

code, and also provides a high level of analog integration.

An internal voltage regulator allows for single-rail operation. Enhancements have been made to the HRPWM 

module to allow for dual-edge control (frequency modulation). Analog comparators with internal 10-bit references 

have been added and can be routed directly to control the ePWM outputs. The ADC converts from 0 to 

3.3-V fixed full-scale range and supports ratio-metric VREFHI/VREFLO references. The ADC interface has been 

optimized for low overhead and latency.
