The frequency of ht32f65532g is up to 60MHz, and the main resources include flash 32KB and SRAM 4KB. Two comparators, one operational amplifier, one 2msps SAR ADC, and powerful peripheral functions such as mctm, gptm and hardware divider are built in the 1-shun FOC control. The square wave is more imported, and there is no hall exclusive filter, which can make the startup more stable. The communication interface is configured with uart/usart/i ² C/spi, together with 6-channel PDMA and crc-16/32, can improve the immediacy and security of communication. The gate driver integrates bootstrap diodes, with undervoltage, over temperature and shot through protection mechanisms.



The ht32f65532g package adopts 32 pin QFN (4 × 4) And 48 pin LQFP EP, with up to 28 gpios, it has high integration and high cost performance. At the same time, it provides ht32f series brushless DC motor development platform, which can speed up customer product development and evaluation timeliness.
