INTRODUCTION:

TMS320F28027 from the 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, as well as providing 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 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/latency.
