Texas Instruments' F2802x Piccolo 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 full-scale range and supports ratio-metric VREFHI / VREFLO references. The ADC interface has been optimized for low overhead and latency.
