Description

The F2806x Piccolo 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 High-Resolution Pulse Width Modulator (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.
