The F2803x Piccolo™ family of microcontrollers provides the power of the C28x™ core and Control Law Accelerator (CLA) 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.

Piccolo F28035太阳能开发套件
The Piccolo F28035 based solar explorer kit is intended to give designers the opportunity to evaluate different power stages used in solar applications in a safe, low voltage environment. This kit also offers designers of single panel off-grid applications such as lighting or motor control systems a robust development platform to start from by utilizing the 36VDC intermediate bus. All of the primary application power stages are controlled with a single C2000 MCU, including a single switch boost stage for maximum power point tracking, a SEPIC battery charging stage, and a grid-tie-capable DC/AC inverter stage capable of outputting 24VAC. Integrated USB JTAG emulation eliminates the need for external JTA...
