3 Description

C2000™ 32-bit microcontrollers are optimized for processing, sensing, and actuation to improve closed-loop

performance in real-time control applications such as industrial motor drives; solar inverters and digital power;

electrical vehicles and transportation; motor control; and sensing and signal processing. The C2000 line includes

the Premium performance MCUs and the Entry performance MCUs.

The TMS320F2837xD is a powerful 32-bit floating-point microcontroller unit (MCU) designed for advanced

closed-loop control applications such as industrial motor drives; solar inverters and digital power; electrical

vehicles and transportation; and sensing and signal processing. To accelerate application development, the

DigitalPower software development kit (SDK) for C2000 MCUs and the MotorControl software development

kit (SDK) for C2000™ MCUs are available. The F2837xD supports a new dual-core C28x architecture that

significantly boosts system performance. The integrated analog and control peripherals also let designers

consolidate control architectures and eliminate multiprocessor use in high-end systems.

The dual real-time control subsystems are based on TI’s 32-bit C28x floating-point CPUs, which provide

200MHz of signal processing performance in each core. The C28x CPUs are further boosted by the new TMU

accelerator, which enables fast execution of algorithms with trigonometric operations common in transforms and

torque loop calculations; and the VCU accelerator, which reduces the time for complex math operations common

in encoded applications.

The F2837xD microcontroller family features two CLA real-time control coprocessors. 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. The dual C28x+CLA architecture enables intelligent partitioning between various system tasks. For

example, one C28x+CLA core can be used to track speed and position, while the other C28x+CLA core can be

used to control torque and current loops.
