Toshiba Launches Microcontrollers Realizing Highly Accurate Mechanical Control
Incorporates Toshiba Original Coprocessor, "PSC”

TOKYO - Saturday, September 28th 2013 [ME NewsWire]

(BUSINESS WIRE)-- Toshiba Corporation (TOKYO:6502) today announced that it will launch new ARM Cortex™-M3-core-based TX03 series microcontrollers, "TMPM343F10XBG”, "TMPM343FEXBG” and "TMPM343FDXBG”, which realize highly accurate mechanical control. Sample shipments will start in November this year.

Some applications, such as controlling the lens of a digital camera, require two simultaneous control operations: high speed, low noise servo control of multiple mechanisms, such as motors and actuators1; along with sensor control to ensure accurate position, which requires multiple microcontrollers, dedicated motor driver ICs, and so on.

The new microcontrollers integrate Toshiba’s original coprocessor, the "PSC”2, motor driver units that can directly connect to and control motor drives, and amplifier circuits to control sensors. This enables highly accurate, simultaneous control of multiple mechanisms by a single microcontroller and also contributes to materials and PCB size reductions.

The product line-up offers three different memory sizes, allowing selection to meet system requirements.

Applications: Attitude control of radio-controlled air planes and robots; motion sensory control for video games; and applications in servo controls, such as encoding of industrial servo motors
