C2000

C2000. The C2000 series is a family of 32-bit microcontrollers and digital signal controllers developed by Texas Instruments, designed specifically for real-time control applications. It combines the processing power of a digital signal processor with the integrated peripherals of a microcontroller, making it a cornerstone in embedded control systems. The architecture is optimized for tasks requiring high-speed computation, precise timing, and robust connectivity, serving as a critical component in advanced industrial and automotive electronics.

Overview

Introduced in the late 1990s, the C2000 platform was engineered to bridge the gap between traditional microcontrollers and dedicated digital signal processors for control-oriented tasks. The series is built around the proprietary C2xLP core, which integrates hardware accelerators like the Control Law Accelerator and Trigonometric Math Unit to offload complex mathematical operations from the main central processing unit. These devices are programmed primarily using C/C++ and are supported by a comprehensive ecosystem from Texas Instruments, including the Code Composer Studio integrated development environment. Key markets for these controllers include renewable energy systems, industrial automation, automotive electronics, and digital power supply designs, where they manage motor control, power conversion, and sensing algorithms.

Architecture

The core architecture of the C2000 series is based on the C28x CPU, a 32-bit fixed-point or floating-point processor capable of executing instructions in a single clock cycle for deterministic performance. A distinctive feature is its Harvard architecture, which uses separate buses for program and data memory to enhance throughput, supported by integrated Flash memory and RAM on-chip. Critical to its control prowess are specialized peripherals such as high-resolution pulse-width modulation modules, high-speed analog-to-digital converters, and enhanced capture blocks for precise signal timing. The architecture also includes dedicated co-processors like the Viterbi, Complex Math, CRC Unit and enhanced control peripherals to manage communication protocols including CAN and Ethernet without burdening the main core.

Development Tools

Primary software development for the C2000 is conducted within Code Composer Studio, an integrated development environment based on the Eclipse framework that provides editors, compilers, and debuggers. Hardware evaluation and prototyping are facilitated by development kits such as the LAUNCHXL series and application-specific kits like the DRV8301 motor control board. The software ecosystem is bolstered by Texas Instruments' extensive library of application software, including the DigitalPower Software Development Kit, Motor Control Software Development Kit, and foundational C2000ware driver libraries. Third-party tools from companies like IAR Systems and Green Hills Software also offer alternative compilers and debuggers, while support for real-time operating systems comes from providers including FreeRTOS and TI-RTOS.

Applications

C2000 controllers are extensively deployed in motor control applications, precisely driving brushless DC motors and permanent magnet synchronous motors in appliances, robotics, and electric vehicles. In power electronics, they form the computational heart of solar inverters, uninterruptible power supply systems, and server power supply units, performing complex maximum power point tracking and power factor correction algorithms. The automotive industry utilizes them in electric power steering, battery management systems, and on-board chargers, while industrial automation leverages them for programmable logic controllers, robotic arm control, and sensor fusion. Their real-time capabilities also make them suitable for medical devices like insulin pumps and digital imaging equipment.

Variants and Families

The C2000 portfolio is organized into several distinct series, each targeting specific performance and integration points. The Piccolo family, including devices like the TMS320F28004x, offers cost-effective solutions with integrated analog comparators and enhanced control law accelerator for entry-level real-time control. The Delfino line, such as the TMS320F2837xD, features dual-core C28x processors and high-performance floating-point units for computationally intensive applications like advanced motor control. The F2838x and F2837xD series integrate ARM Cortex-M cores alongside the C28x, enabling heterogeneous processing for complex systems. Specialized variants include the C2000 real-time microcontroller safety-certified devices for functional safety in markets governed by ISO 26262 and IEC 61508 standards.
