TOKYO--(BUSINESS WIRE)--Toshiba Corporation (TOKYO:6502) today announced the launch of a new microcontroller, "TMPM37AFSQG", as the latest addition to its ARM® Cortex®-M3-based "TX03 series". The new IC is the world’s smallest[1]vector control[2] microcontroller to incorporate an original coprocessor,[3] the “Vector Engine Plus,” [4] and a pre-driver[5] to implement brushless DC motor control. Sample shipments will start in the middle of January 2016.
The TMPM37AFSQG contains a pre-driver that directly drives the MOSFET in small applications, including small fan motors. A single-power supply is also feasible since the power of the microcontroller is internally supplied from the power of the pre-driver. [6] Furthermore, peripheral parts, such as an Op-Amp[7] essential for current detection using shunt resistors[8] and a comparator[9] for over-current detection, have been incorporated in a small package (QFN32 5 x 5 mm), minimizing the mounting space.
The new IC can perform highly efficient vector control, realizing low vibration, low noise motor control. The TMPM37AFSQG greatly improves motor performance in user applications.

| [1]: | Microcontrollers based on ARM® Cortex®-M3 that incorporate a vector engine and pre-driver. Toshiba survey, as of November 30, 2015. | |
| [2]: | Vector Control: Advanced technology for efficient control of motor rotation from low to high speeds. | |
| [3]: | Coprocessor: A processor completely separate from the CPU core and a computing unit. | |
| [4]: | Vector Engine Plus: A Toshiba-developed coprocessor for vector control functioning independently from the CPU in the microcontroller. | |
| [5]: | Pre-driver: Drivers for driving the driver. Required for driving power devices such as an FET or an IGBT for driving a motor. | |
| [6]: | Single power supply operation is allowed when a pre-driver operation voltage (VM) is 12V. When VM is 24V, the power supply for the microcontroller (5V) should be an external source. | |
| [7]: | Op-Amp: Operational Amplifier. A circuit in an amplifier with a non-inverting input terminal, inverting input terminal and one output terminal. | |
| [8]: | Shunt resistor: A resistor to be inserted into a circuit for current measurement. | |
| [9]: | Comparator: A device that receives two inputs of current of voltage with different levels and outputs a digital signal that indicates which is larger. | |
