The Holtek HT32F61041 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), SysTick timer, and including advanced debug support.

The device operates at a frequency of up to 20 MHz to obtain maximum efficiency. It provides 64 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, ADC, I2C, USART, UART, SPI, MCTM, GPTM, PWM, BFTM, CRC-16/32, RTC, 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 integrates USB Power Delivery (PD) PHY communication protocols and are compliant with USB PD 3.1/PPS specification.

The above features ensure that the device is suitable for use in a wide range of PD applications, especially in areas such as power bank, car charger and various products powered by PD protocol.
