Holtek launches new generation Arm Cortex-M0+ brushless DC motor control dedicated MCU

     Holtek launched a new generation of Arm® Cortex®-M0+ brushless DC motor control microcontroller HT32F65232, which is suitable for Hall sensor or Sensor-less 1-shunt FOC and square wave Sensor-less control. The frequency can reach up to 60MHz, with 2.5V~5.5V wide voltage operation, the system voltage of 5V can bring higher analog signal resolution and the benefits of being less susceptible to noise interference when the motor is driven, with high performance, high cost performance and high integration degree features. Suitable for electric scooters, range hoods, vacuum cleaners, various types of pumps, fans, etc.

     The Flash capacity of the HT32F65232 is 32KB and the SRAM capacity is 4KB. For 1-Shunt FOC and square wave Sensor-less control, a set of OCP (OPA+CMP0), a dedicated square wave Sensor-less comparator CMP1, a 12-channel 2Msps SAR ADC and powerful MCTM, GPTM and Peripheral functions such as hardware divider. The communication interface is configured with UART/USART/I²C/SPI, and with 6-channel PDMA and CRC16/32, it can improve the immediateness and security of communication.

     The package type adopts 32-pin QFN (4×4) and 48-pin LQFP, with up to 44 GPIOs. Holtek provides HT32 series brushless DC motor development platform (HT32 Series BLDC Workshop), which supports Hall sensor or Sensor-less FOC control.
