The TMS320F28002x (F28002x) is a member of the C2000™ real-time microcontroller family of scalable, ultralowlatency devices designed for efficiency in power electronics, including but not limited to: high power density,high switching frequencies, and supporting the use of GaN and SiC technologies.

These include such applications as:

• Industrial motor drives

• Motor control

• Solar inverters

• Digital power

• Electrical vehicles and transportation

• Sensing and signal processing

The real-time control subsystem is based on TIs 32-bit C28x DSP core, which provides 100 MHz of signalprocessingperformance for floating- or fixed-point code running from either on-chip flash or SRAM. The C28xCPU is further boosted by the Trigonometric Math Unit (TMU) and VCRC (Cyclical Redundancy Check)extended instruction sets, speeding up common algorithms key to real-time control systems.

High-performance analog blocks are integrated on the F28002x real-time microcontroller (MCU) and are closelycoupled with the processing and PWM units to provide optimal real-time signal chain perf...
