FREMONT, CA: Texas Instruments, a semiconductor design and manufacturing company, expands its C2000 Delfino microcontroller unit (MCU) portfolio with the announcement of two new products namely TMS320F28379D and TMS320F28379S. Built to support Texas Instruments’ DesignDRIVE Position Manager technology, the new MCUs performs on-chip decoding to improve system performance through enabling faster control loop performance and reducing communication latency.

Both the Delfino TMS320F2837S and TMS320F28379D are powerful 32-bit floating-point MCUs that support advanced closed-loop control applications such as industrial drives and servo motor control; solar inverters and converters; digital power; transportation; and power line communications. As a System-on-Chip (SoC), it delivers value with its  support for the Position Manager technology on-chip which is suitable for both digital and analog position sensors such as Resolver, SIN/COS, QEP, BiSS-C and EnDAT2.2.

Using Texas Instruments’ DesignDRIVE, a single hardware and software platform, engineers can develop and figure out solutions for a variety of industrial drive and automatic devices that uses error-sensing negative feedback to correct the performance of a mechanism. As the platform is based on the real-time control framework of C2000 MCUs, it helps in developing industrial inverter and servo drives that are used in robotics, computer numerical control machinery (CNC), elevators, materials conveyance, transportation and other industrial manufacturing applications.

DesignDRIVE Kit is a single platform to develop and evaluate Texas Instruments solutions for many drive topologies. The new DesignDRIVE Development Kit (IDDK) hardware includes: an integrated full power stage to drive a three-phase motor that eases evaluation of a diverse range of feedback sensing and control topologies; multi-sense current topologies; high performance real time control; multi-protocol encoder interface circuits on-board; flexible real time connectivity; functional safety expansion port; and configurable isolation partitioning. Supported by the C2000 controlSUITE package, the software part of the kit includes vector control of motors that incorporates current, speed and position loops to help developers start their evaluation and development in an efficient way.

"We approve of Texas Instruments' successful implementation and testing of Position Manager to our EnDat specifications and we look forward to working with TI as they enable new EnDat capabilities for our customers," says Herbert Reiter, Senior Product Manager, HEIDENHAIN.
