Toshiba Launches Microcontrollers Realizing Highly Accurate Mechanical Control– Sep 27, 2013– Tokyo, Japan (Techreleased) – Toshiba Corporation 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.

ARM Cortex-M3-core-based TX03 series microcontrollersSome 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 actuators[1]; 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
