TMS320F2806x - Piccolo Microcontroller

15+ new C2000™ Piccolo MCUs offering floating-point precision and increased math capabilities

The F2806x 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...3.3 V fixed full scale range and supports ratio-metric VREFHI/VREFLO references. The ADC interface has been optimized for low overhead/latency.
