Using the new C2000™ Delfino™ MCU and DesignDRIVE Position Manager technology

TI announced that it is launching the industry's first on-chip solution that supports both analog and digital position sensors. The new TMS320F28379D and TMS320F28379S microcontrollers (MCUs) are additions to TI's C2000™ Delfino™ MCU portfolio and can be easily interfaced with position sensors using DesignDRIVE Position Manager technology.

This solution improves system performance and achieves even faster control loop performance by performing decoding tasks on-chip and reducing communication latency.

In addition, developers can lower system costs by reducing the board space required for FPGA or ASIC-based solutions.

Position Manager saves developers time in development by providing the basic functions required to interface with EnDat2.2, BiSS-C, Resolver, and SIN/COS sensors.

The DesignDRIVE platform, based on the real-time control architecture of TI's C2000 MCU, is suitable for industrial inverters and servo drives used in robots, CNC (computer numerical control) equipment, elevators, material handling, transportation, and other industrial manufacturing applications.


DesignDRIVE is a single hardware and software platform that enables engineers to develop solutions for various types of industrial drive and servo topologies and to easily evaluate them. Position Manager is a new technology added to DesignDRIVE that allows developers to easily interface with digital and analog position sensors.

The TMS320F28379D and TMS320F28379S MCUs are the first MCU products in the C2000 portfolio to support Position Manager technology on-chip. By using Position Manager, a core component of the DesignDRIVE solution, industrial drive system designers can reduce the engineering effort required to develop, support, and maintain the FPGAs or ASICs needed to connect to these sensors.

TI’s Position Manager technology is compatible with both digital and analog position sensors, providing the flexibility to support various sensor types using a single C2000 Delfino MCU. Sensor types include EnDat 2.2, BiSS-C, Resolver, SIN/COS, and incremental encoders (including Clockwise/Counterclockwise (CW/CCW) protocols).

TI is the only company that supports both digital and analog position sensors for industrial applications. TI tested compatibility with this on-chip solution in collaboration with Heidenhain, a leader in the position sensor field. Herbert Reiter, Senior Product Manager at Heidenhain, stated, “Heidenhain tested Position Manager on its EnDat and confirmed a successful implementation.” "We look forward to continuing to cooperate with TI to provide new EnDat features to our customers," he said.

By using the C2000 DesignDRIVE development kit, you can easily evaluate various types of motor drive topologies and expand them by adding real-time Ethernet communication or “functional safety” topologies, thereby enabling the development of more comprehensive and integrated system solutions.

DesignDRIVE is supported by TI's C2000 controlSUITE™ package and includes examples for motor vector control, including current, speed, and position loops, enabling developers to quickly and easily perform evaluation and development. Users can also download TI's Code Composer Studio™ integrated development environment (IDE). Code Composer Studio provides code generation and debugging capabilities.

TI's C2000 F28379D and F28379S MCUs are fully compatible with F28377D and F28377S for model-based simulation and software development. These MCUs are currently supported by MathWorks' Simulink and Embedded Coder . Users can also download interface and power reference designs for motor drives. These reference designs can be used as is or modified to suit specific needs.

In addition, along with C2000 MCUs and DesignDRIVE technology, developers can use TI's new ISO5852S reinforced isolation gate driver family when developing industrial drive power stages. These products offer the industry's highest operating voltage up to 1.5 kVrms, the industry's highest common mode transient immunity (CMTI) up to 100 kV/ms (minimum), and precise timing. Consequently, they can efficiently drive high-voltage, high-speed switching insulated gate bipolar transistors (IGBTs) and silicon carbide (SiC) power switches. Prices for these products start at $2.15 per unit for quantities of 1,000.
