3 Description

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 F2802x family of microcontrollers provides the power of the C28x core 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 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 PWM outputs. The ADC converts from 0 to 3.3-V fixed fullscale

range and supports ratio-metric VREFHI/VREFLO references. The ADC interface has been optimized for low

overhead and latency.
