Texas Instruments TMS320F2807x 32-Bit Microcontrollers (MCUs)

Texas Instruments TMS320F2807x 32-Bit Microcontrollers (MCUs) are part of the Piccolo family. These MCUs are well suited for advanced closed-loop control applications such as industrial motor drives; solar inverters and digital power; electric vehicles and transportation; and sensing and signal processing. The F2807x is a 32-bit floating-point microcontroller based on TI’s industry-leading C28x core. This core is boosted by the trigonometric hardware accelerator, which improves the performance of trigonometric-based algorithms with CPU instructions. These instructions include sine, cosine, and arctangent functions, which are common in torque-loop and position calculations.

The F2807x microcontroller family features a CLA real-time control coprocessor. The CLA is an independent 32-bit floating-point processor that runs at the same speed as the main CPU. The CLA responds to peripheral triggers and executes code concurrently with the main C28x CPU. This parallel processing capability can effectively double the computational performance of a real-time control system. By using the CLA to service time-critical functions, the main C28x CPU is free to perform other tasks, such as communications and diagnostics.
