Replace expensive resolver-to-digital conversion solutions with TI's new C2000™ Microcontroller (MCU) Resolver Kit

April 10, 2014

HOUSTON, TX -- Texas Instruments announces its first programmable microcontroller (MCU) solution to handle resolver-to-digital decoding: The C2000™ MCU Resolver Kit. Because the resolver is an analog, rotary electrical transformer, it has historically required an application-specific circuit — which can be costly and space consuming – to convert to digital signals for use by a digital processor in a control system. However, TI's new C2000 MCU Resolver Kit shows designers how to implement the digital conversion using software on programmable C2000 MCUs, saving system cost and space in a variety of industrial applications, including robotics, servo drives, automation, avionics and transportation.

Features and benefits of the C2000 MCU Resolver Kit:

• Replaces expensive, dedicated resolver-to-digital chipsets with low-cost MCUs to simplify and reduce cost in systems.
• Extends functionality by allowing an MCU to handle resolver-to-digital decoding, as well as other software programmable real-time functions, such as additional analog-to-digital converter (ADC) sampling and processing, encoder and hall interfaces, digital signal processing (DSP) front-end, state logic, tasks to assist with functional safety and full control loops.
• Provides complete hardware and consists of a C2000 controlCARD-compatible printed circuit board (PCB) with on-board JTAG emulation for software debug, a resolver interface with filtering, UART and SPI interfaces, four digital-to-analog converter (DAC) outputs for debug and a 15V power supply.
• Includes software and hardware development packages: ◦Software: Free download of C2000 controlSUITE and Code Composer Studio™ integrated development environment (IDE), an Eclipse-based IDE for embedded software development.
• Hardware: Full build of materials, schematics and PCB design files.
• Supports four software project variants running on three different C2000 controlCARDs (all purchased separately):TMDSCNCD28335 (floating-point), TMDSCNCD28035 (fixed-point) or parallel control law accelerator (CLA) and TMDSCNCD28027 (fixed-point).

Pricing and availability

The C2000 MCU Resolver Kit (TMDSRSLVR) is available today for $179 USD. C2000 controlCARDs are available separately starting at $49. The controlSUITE software and documentation are available for download. The C2000 MCUs capable of running the resolver software are available starting from $1.85 USD 1ku SRP (TMS320F280200).
