Piccolo Microcontroller - TMS320F28055

TMS320F28055 (ACTIVE)

Piccolo Microcontroller

 

Description

The F2805x Piccolo family of microcontrollers (MCUs) provides the power of the C28x core and CLA coupled with highly integrated control peripherals in low pin-count devices. This family is code-compatible with previous C28x-based code, and also provides a high level of analog integration.

An internal voltage regulator allows for single-rail operation. Analog comparators with internal 6-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.

The Analog Front End (AFE) contains up to seven comparators with up to three integrated DACs, one VREFOUT-buffered DAC, up to four PGAs, and up to four digital filters. The PGAs can amplify the input signal in three discrete gain modes. The actual number of AFE peripherals will depend upon the TMS320F2805x device number. See for more details.
