Overview
The TMS320F28035RSHT is a member of the Piccolo™ family of microcontrollers from Texas Instruments. This device is built around the high-efficiency 32-bit TMS320C28x CPU, which operates at 60 MHz with a cycle time of 16.67 ns. It integrates a Control Law Accelerator (CLA) and various control peripherals, making it suitable for applications requiring high performance and low power consumption.
The microcontroller is designed for code compatibility with previous C28x-based code and offers a high level of analog integration. It features an internal voltage regulator for single-rail operation, enhancements to the High-Resolution PWM (HRPWM) for dual-edge control, and analog comparators with internal 10-bit references.
