NEW 32-Bit ARM Cortex™-M3 with integrated motor control capabilities from Toshiba

Toshiba Electronics Europe has further expanded its range of devices and tools for motion control applications with a compact and integrated ARM Cortex™-M3 microcontroller that will improve application performance and efficiency while reducing component count and board space.

The 32-bit TMPM374FW IC is launched with a dedicated Starter Kit that provides all the hardware, software and documentation needed for immediate device evaluation and rapid development and prototyping.

Designed specifically to be used with three-phase BLDC and induction motors, the new TMPM374FW microcontroller includes an integrated hardware vector engine and single-channel programmable motor drive output.

Supplied in different packages ranging from 44 to 64pin down to 7x7mm with an integrated 80MHz ARM Cortex-M3 core, our new microcontroller improves application performance and efficiency whilst reducing component count and board space.

Designed for use with three-phase brushless DC and induction motors, the TMPM374FW microcontroller will suit industrial and home appliance applications requiring efficient and accurate field oriented control of fans, pumps and compressors. An integrated hardware vector engine (VE) and single-channel programmable motor drive output ensure precision control and rapid response without additional hardware, CPU overhead or time-consuming software development.

Toshiba's PMD3+ technology comprises a three-phase PWM generator, dead time controller, protection circuit and ADC timing network and allows complete control of a three-phase motor through a simple register setting. A total processing time of just 9µs (at a core frequency of 80MHz) means that the hardware VE block offers significant performance improvements when compared with a software-based vector control algorithm running on a host microcontroller.

Dedicated starter kits are available providing all the hardware, software and documentation to enable rapid development and prototyping. The kit also makes it simple to adapt the design for use with a different motor by using other modules or the customer's own drive stage.
