TOKYO — (BUSINESS WIRE) — November 30, 2015 — 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.
