Piccolo Microcontroller


Not Recommended for New Designs (NRND)

Replaced By TMS320F28022 – The device has the SAME FUNCTIONALITY and PINOUT as the compared device but is NOT an exact equivalent.

TI does not recommend using this part in a new design. This product continues to be in production to support existing customers.


The F2802x0 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. 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.
