TMS320F28027-Piccolo Microcontroller

Description

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, and also provides a high level of analog integration.

An internal voltage regulator allows for single-rail operation. Enhancements have been made to the HRPWM 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 V_REFHI/V_REFLO references. The ADC interface has been optimized for low overhead and latency.
