  • Page 6: Key Microcontroller Features

    1. Key microcontroller features At its core, the SmartMCD™ board uses the TB9M003FG MCU. The TB9M003FG (U1) is Toshiba’s implementation of the 32-bit ARM® Cortex®-M0 core, capable of operating at a maximum frequency of 40MHz. It includes 64KB of code flash memory with ECC SEC/DED, allowing the programming of control methods and parameters tailored to specific motor and application requirements.

    2. MOSFET Power Stage As mentioned, the SmartMCD™ board includes an integrated inverter comprising of six small-package, AEC-Q101 qualified MOSFETs (SSM6K809R - from Q2 to Q7) for efficient power management, connected via populated jumpers on the J5 header (1). These MOSFETs are driven by gate-signal outputs from the TB9M003FG (U1).

    3. Power Supply The main power supply, which ranges from 6V to 18V (typically 12V), is provided to the TB9M003FG (U1) via the terminal. This power supply also feeds the entire inverter circuit and the step-down DC-DC converter, the MCP16331 (U3). The presence of active external power can be visually confirmed by a green PWR LED located near the connector.
