TMS320F280270DAS Texas Instruments 32bit MCU

TMS320F280270DAS Overview

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 V_REFHI/V_REFLO references. The ADC interface has been optimized for low overhead and latency.
