Toshiba To Launch Microcontroller

Toshiba To Launch Small Package Microcontroller With Built-in Pre-Driver For Motor Control–Dec 01, 2015– Tokyo, Japan (Techreleased) – Toshiba Corporation 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.

Toshiba To Launch Microcontroller

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.
