The Holtek HT32F50020/HT32F50030 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 16 MHz with a Flash accelerator to obtain maximum efficiency. It provides up to 32 KB of embedded Flash memory for code/data storage and 2 KB of embedded SRAM memory for system operation and application program usage. A variety of peripherals, such as ADC, I2C, UART, SPI, SCTM, BFTM, RTC, WDT, LED controller and 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 above features ensure that the devices are suitable for use in a wide range of applications, especially in areas such as white goods application controllers, power monitors, alarm systems, consumer products, handheld equipment, data logging applications, motor controllers and so on.
