2.3.1 C2000 MCU F2838x

C2000 MCUs are part of an optimized MCU family for real-time control application. Fast and high-quality analog-to-digital controller (ADC) enables accurate measurement of the current and voltage signals, and an integrated comparator subsystem (CMPSS) provides protection for over-current and over-voltage without use of any external devices. The optimized CPU core enables fast execution of control loop. Trigonometric operations are accelerated using the on-chip trigonometric math unit (TMU). The solution also provides an option to use the control law accelerator (CLA) on the F2838x. The CLA is a co-processor that can be used to alleviate CPU burden and enable faster-running loops or more functions on the C2000 MCU.
