TI Korea (CEO Kent Jeon, www.ti.com/ww/kr ) November 27, 2012 – TI (CEO Kent Jeon) announced the launch of a new motor control solution consisting of motor control software, application-specific development tools, and comprehensive support, including the highly integrated C2000™ Piccolo™ F2805x microcontrollers that simplify the complexity of motor control design. These Piccolo microcontroller products are designed for various types of three-phase inverter motor control applications, enabling improved power efficiency and control performance in electric pumps, fans, traction drives, textile equipment, and more.

These new Piccolo F2805x microcontrollers integrate multiple analog components on-chip to improve system efficiency and reduce the number of discrete parts. Additionally, the Piccolo F2805x microcontrollers provide the intelligence and performance of the TMS320C28x™ DSP core and integrate an on-chip C-programmable Control Law Accelerator (CLA). The CLA is a 32-bit floating-point arithmetic accelerator designed to operate independently of the CPU core and handle time-sensitive control algorithms or DSP processing. By utilizing spare CPU time to process motion profiling, system management, communications, and safety checks, it can improve performance for closed-loop applications by up to five times.

Key Features and Advantages of the Piccolo F2805x Microcontroller
• C28x CPU operating at 60 MHz and C programmable 32-bit floating-point CLA coprocessor operating at 60 MHz: Improves ease and flexibility of programming and enables direct access to on-chip peripherals, thereby allowing parallel execution of algorithms and control loops. CLA features rapid system response, high KHz control loops, enhanced triggering, and fault detection.
• Extended Storage: Provides up to 128KB of Flash and up to 20KB of SRAM. Boot ROM within protected areas of Flash and ROM, along with dual 128-bit security keys, enables code security for the entire device and mixed-source software development.
• On-chip communication interfaces: Enhanced connectivity performance for real-time communication through on-chip communication interfaces such as SPI modules, I2C bus, CAN 2.0, and three SCI (UART) modules.
• Improved system efficiency and reduced Bill of Materials (BOM) costs through the integration of various analog functions:
- Detects phase current/phase voltage of synchronous motors with a 12-bit ADC of up to 2.3 MSPS – Dual Sample and Hold
- Provides 14 enhanced pulse-width-modulation (PWM) channels with fault management capabilities, enabling multi-motor control and power conversion.
- Provides individual current feedback for each motor phase, integrated fault protection, and precise on-time feedback with 7 Windows analog comparators equipped with a 10-bit DAC.
- Dual zero-pin oscillators enhance system robustness by integrating the clock source on-chip and providing a secondary backup oscillator for flexible recovery from clock fault conditions.
- Voltage regulators enable lower system complexity and cost, and drive microcontrollers with a single voltage power rail.
- Up to four Programmable Gain Amplifiers (PGAs) allow input signal gain to be adjusted via variable resistors prior to ADC conversion, saving cost and board space.
- The 32-bit eCAP (enhanced input capture module) and eQEP (enhanced quadrature encoder pulse) modules for motor control sensor signals accurately detect and capture the position and velocity of rotational and motion systems.

Tools, software, training, and support to assist in motor control development
Designers can conveniently perform development tasks using TI’s Motor Control Development Kit, which includes free open-source motor control software libraries and examples. These libraries and example projects are available for both the C28x and CLA cores of the Piccolo F2805x microcontroller and include essential motor control computation functions as well as device-specific peripheral configurations. Designed to simplify development, these motor control libraries are fully modular and can be conveniently used at every stage of the development process. Software code blocks can be connected in the same way as connecting blocks in a block diagram. Designers simply connect the software blocks from the motor control libraries, adjust their parameters, compile the code, and program it into the Piccolo F2805x microcontroller's flash memory.

With C2000 Piccolo-based modular development tools, you can evaluate various C2000 microcontrollers to select a cost-effective product that meets your desired peripheral functions. The C2000 LaunchPad, controlCARD, controlSTICK, and C2000 Experimenter Kit are included, and all tools come with TI's Code Composer Studio v5 integrated development environment and C2000 controlSUITE™ software (including an easy-to-use open-source demo GUI, software examples, and motor control development resources). In addition, you can take motor control training online, and TI's E2E Community provides 24/7 support.
