1.2 Description
The 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
C28-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 V_REFHI/V_REFLO references. The
interface has been optimized for low overhead/latency.
