Enable dual control of two DC brushless motors at once
 

TOKYO – Toshiba Corporation (TOKYO: 6502) today announced the launch of two microcontrollers, "TMPM470FDFG" and "TMPM475FDFG," as the latest additions to its ARM® Cortex®-M4F based TX04 series microcontrollers. The new devices can control two DC brushless motors simultaneously. In addition, "TMPM475FDFG" incorporates a CAN[1] controller that supports a wide range of applications, from home appliances to factory automation systems. Sample shipments will start at the beginning of February.
 

Recent years have seen growing demand for lower energy consumption by motors used in home appliances and factory automation systems. Given this, improved vector control performance is required to achieve highly efficient motor control.
 

Based on the high-performance ARM® Cortex®-M4F, "TMPM470FDFG" and "TMPM475FDFG" can operate at up to 120MHz.

Both incorporate two modules, each containing a programmable motor driver, 12-bit AD converter and vector engine. As a result, two DC brushless motors can be efficiently and simultaneously operated by one chip.
 

The "TMPM475FDFG" also integrates a CAN controller which is required for factory automation systems. This ensures a wide range of usability, from home appliances to industrial applications.
 

Note: [1] Controller Area Network.

Applications

  • Home appliances (air-conditioners, washing machines, or refrigerators)
  • Inverter equipment for factory automation systems
  • AC servo mechanism controls

Key Features of New Products

  • ARM® Cortex®-M4F core. Operates at up to 120MHz.
    Interactive PWM, Minimum unit: 8.3 ns
  • Two DC brushless motors operate with high efficiency and simultaneously.
    Two modules, each containing a programmable motor driver, 12-bit AD converter and vector engine, reduce load on software.
  • A high-speed PWM implements 1-shunt current detection.
    Built-in 12-bit AD converter with a conversion time of 1µs.
  • Built-in CAN controller (TMPM475FDFG)
