Overview
The TMS320F28068PFPS is a member of the TMS320F2806x Piccolo™ family of microcontrollers from Texas Instruments. This device is built around the high-efficiency 32-bit TMS320C28x CPU, which operates at a clock speed of up to 90 MHz with an 11.11-ns cycle time. The F2806x series is designed to provide a high level of integration, including advanced control peripherals, making it suitable for demanding control applications.
The microcontroller features a Harvard bus architecture, 16 × 16 and 32 × 32 Multiply and Accumulate (MAC) operations, and a Control Law Accelerator (CLA) for enhanced performance. It also includes an internal voltage regulator for single-rail operation and supports various low-power modes for power savings.
