The Holtek HT32F67742 devices are high performance, low power consumption 32-bit microcontrollers 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 devices operate at a frequency of up to 60 MHz with a Flash accelerator to obtain maximum efficiency. It provides up to 64 KB of embedded Flash memory for code/data storage and up to 8 KB of embedded SRAM memory for system operation and application program usage. A variety of peripherals, such as USB2.0 FS, Hardware Divider DIV, SPI, USART, UART, SCI, I2C, GPTM, PWM, BFTM, CRC-16/32, RTC, WDT, ADC, LCD and SW-DP (Serial Wire Debug Port), etc., are also implemented in the devices. Several power saving modes provide the flexibility for maximum optimization between wakeup latency and power consumption, an especially important consideration in low power applications.
