Holtek – New Arm® Cortex®-M0+ BLDC MCU

Holtek’s newest microcontroller device, the HT32F65232, is an Arm® Cortex®-M0+ MCU suitable for hall sensor based BLDC motor control or sensor-less one-shunt Field Oriented Control (FOC) and square wave sensor-less control. It has an operating frequency of up to 60MHz and a wide operating voltage range of 2.5V~5.5V. When the system voltage is 5V, the device can provide higher analog signal resolution and less noise interference when driving motors. With the characteristics of high efficiency, excellent price/performance ratio and a high level of functional integration, the device can be widely used in applications such as electric scooters, kitchen ventilators, vacuum cleaners, pumps, fans, etc.

HT32F65232 Motor Control Features

With regard to one-shunt FOC and square wave sensor-less control, the device includes many helpful peripherals like:

  • Over Current Protection function (via Comparators and Op Amps)
  • Comparators
  • Operational Amplifiers
  • 12-channel 2Msps SAR ADC
  • powerful Motor Control Timer (with PWM waveform Generation and programmable dead-time)
  • General Purpose Timer
  • hardware divider
  • other peripheral functions.

Cortex®-M0+ BLDC MCU

Besides Holtek also provides an HT32 Series BLDC Workshop including Hardware and Software Tools to reduce the product development and evaluation time for motor related products with both Hall sensors and sensor-less FOC control.


General Features

The device contains a 32KB Flash Program Memory and a 4KB SRAM Data Memory, supporting multiple booting modes.

Additionally, there are a range of communication interfaces including UART, USART, I²C and SPI, which can be combined with the 6-channel PDMA and CRC16/32 functions to improve communication response and security.

The device is supplied in 32-pin QFN(4×4) and 48-pin LQFP package types, which contain up to 44 GPIO pins. It’s operating in temperatures between -40°C and +105°C
