Product Usage Instructions

Choose a proper 32-bit MCU for your product application considering factors like performance, power consumption, package type, tooling, and cost.
Familiarize yourself with the specific features and advantages of the HT32 M0+ Series and HT32 M3 Series MCUs.
Determine the required interfaces for your application and select the appropriate MCU that supports those interfaces. Consider the memory requirements of your application and choose an MCU with sufficient flash memory and SRAM.
Understand the available peripherals and select an MCU that provides the necessary peripherals for your application.
Take into account any analog features required for your application, such as A/D converters or comparators.
Refer to the HT32 MCU Selection Guide to find the specific part number that matches your desired specifications. Ensure that you have the necessary power supply voltage for the chosen MCU.
Follow the recommended operating frequency range for the MCU.
If programming is required, refer to the IAP and ISP Programming Methods provided by Holtek.
Consult the Holtek website (www.holtek.com) for additional resources, documentation, and support for using their 32-bit MCUs.

Innovative and All-round General Purpose HT32

HT32 BLDC Motor Control Applications

BLDC MCUs with integrated intellengent gate-driver and driver $HOLTEK-MCU- Series-HT32-Arm-Cortex-M $19$$

Under the global energy saving and carbon reduction requirements, the use of BLDC motor design for motor products has become a market trend. Its advantages are small size, high efficiency, low noise, long service life, high power density, etc., but the disadvantages lie in higher cost and high complexity of design techniques. Holtek has released a series of Arm® Cortex®-M0+ core BLDC microcontrollers, which support Hall sensor or sensorless FOC controls. For BLDC motor loads with different voltages and power, BLDC SoC MCUs with integrated intellegent gate-driver and driver are also introduced, which effectively reduces the hardware volume and the complexity of the PCB design. In addition, Holtek also provides a Workshop for motor parameter adjustment and software secondary development, assisting customers to rotate motor smoothly in a short period of time, and to mass-produce the finished BLDC prducts and introduce them into the market in time. With the IEC/UL 60730-1 software certification, the HT32F65xxx series can be widely used in applications such as the fast-growing industrial controls, household applicances, ceiling fans, range hoods, gargen tools, robots, electric scooters, quadcopters, etc.
