Toshiba Extends Support for Efficient Embedded Motion Control with Compact,

32-Bit ARM Micro and Dedicated Starter Kit

Latest ARM Cortex-M3 micro with integrated motor control capabilities supportssingle-channel three-phase BLDC and AC induction motors in industrial and home

appliance designs

Nuremberg, Germany, 1st March, 2011Toshiba Electronics Europe has further expandedits range of devices and tools for motion control applications with a compact and integratedARM Cortex-M3 microcontroller that will improve application performance and efficiencywhile reducing component count and board space. The 32-bit TMPM374FW IC is launchedwith a dedicated Starter Kit that provides all of the hardware, software and documentationneeded for immediate device evaluation and rapid development and prototyping.

Designed for use with three-phase brushless DC (BLDC) and induction motors, theTMPM374FW microcontroller will suit industrial and home appliance applications requiringefficient and accurate field oriented control (FOC) of fans, pumps and compressors. Anintegrated hardware vector engine (VE) and single-channel programmable motor driveoutput ensure precision control and rapid response without additional hardware, CPUoverhead or time-consuming software development.

Supplied in a compact 10mm x 10mm 44-pin LQFP package and operating from a single 5Vsupply, the TMPM374 integrates the 80MHz ARM Cortex-M3 core with 128Kbytes of high-

efficiency NanoFlash memory; 6Kbytes of RAM; the vector engine; Toshibas proprietaryPMD3+ programmable motor drive technology; and a 12-bit analogue-to-digital converter(ADC). The ADC offers a sub-2s conversion speed. Eight-channels of 16-bit timer, awatchdog timer, 3-channel SIO/UART and on-chip voltage regulator are also provided inaddition to power on reset (POR) and oscillation frequency detector (OFD) functionality. The

latter is particular relevant to home appliance designs as it fulfils the basic requirements forthe EN/IEC 60730 and 60335 (Class B) safety standards that apply to this class ofequipment.

Toshibas PMD3+ technology comprises a three-phase PWM generator, dead time controller,protection circuit and ADC timing network and allows complete control of a three-phasemotor through a simple register setting. The hardware-based vector engine manages thethree-phase current input from the ADC, executes the FOC control algorithm and generatesthe appropriate PWM gate signals for the inverter. A total processing time of just 9s (at acore frequency of 80MHz) means that the hardware VE block offers significant performanceimprovements when compared with a software-based vector control algorithm running on ahost microcontroller.

To support the development of applications based on the TMPM374 Toshiba has announceda dedicated modular Starter kit for the microcontroller, which provides everything needed forout-of-box evaluation and prototyping. The kits contents includes a TMPM374 evaluationboard, a 24V three-phase BLDC motor, a suitable drive board, a power supply and a varietyof software and documentation including a board support package (BSP), source code andapplication notes.

Using the kits PC-based graphical user interface designers can configure key motorparameters and manage and monitor factors such as speed, current and torque. The kit alsomakes it simple to adapt the design for use with a different motor by using other modules orthe customers own drive stage.
