HT32F65C33F Datasheet 32-Bit Arm® Cortex®-M0+ BLDC Motor Microcontroller with 3-Channel 32 V Half-Bridge Driver, 32 KB Flash and 8 KB SRAM with 2 Msps ADC, CMP, OPA, PGA, PDMA, DIV, UART, SPI, I2C, MCTM, GPTM, SCTM, BFTM, CRC, UID, LSTM and WDT Revision: V1.00 Date: August 28,2025 32-Bit Arm® Cortex®-M0+ BLDC Motor MCU with 3-Channel 32 V Half-Bridge Driver HT32F65C33F 1 General Description The Holtek HT32F65C33F device is a high performance, low power consumption 32-bit microcontroller based around an Arm® Cortex®-M0+ processor core. The Cortex®-M0+ is a next-generation processor core which is tightly coupled with Nested Vectored Interrupt Controller (NVIC), Sys Tick timer, and including advanced debug support. The device operates at a frequency of up to 60 MHz with a Flash accelerator to obtain maximum efficiency. The device provides 32 KB of embedded Flash memory for code/data storage and 8 KB of embedded SRAM memory for system operation and application program usage. A variety of peripherals, such as Hardware Divider DIV, PDMA, ADC, OPA, PGA, CMP, I2C, UART, SPI, MCTM, GPTM, SCTM, BFTM, CRC-16/32, 96-bit Unique ID, LSTM, WDT, SW-DP (Serial Wire Debug Port), etc., are also implemented in the device. Several power saving modes provide the flexibility for maximum optimization between wakeup latency and power consumption, an especially important consideration in low power applications. The device also includes a 32 V 3-channel half-bridge driver with isolated motor current sensing function and can drive a three-phase BLDC motor. The driver has several internal protection functions and integrates an accurate 5 V output LDO with very low quiescent current. The above Features ensure that the device is suitable for a wide range of applications, especially in 5-cell lithium battery-powered or sub-24V DC applications such as floor fans and water pumps. 1 General Description Rev. 1.00 6 of 52 August 28,2025 2 Features 32-Bit Arm® Cortex®-M0+ BLDC Motor MCU with...
