HT32F50020/HT32F50030 Datasheet 32-Bit Arm® Cortex®-M0+ 5V Microcontroller, up to 32 KB Flash and 2 KB SRAM with 500 ksps ADC, UART, SPI, I2C, SCTM, BFTM, LEDC, RTC and WDT Revision: V1.30 Date: August 25, 2025 32-Bit Arm® Cortex®-M0+ 5V MCU HT32F50020/HT32F50030 1 General Description 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), Sys Tick timer and including advanced debug support. The devices operate at a frequency of up to 16 MHz 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, LEDC, RTC, WDT 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. 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 control and so on. 1 General Description Rev. 1.30 6 of 43 August 25, 2025 2 Features 32-Bit Arm® Cortex®-M0+ 5V MCU HT32F50020/HT32F50030 2 Features Core ▆ 32-bit Arm® Cortex®-M0+ processor core ▆ Up to 16 MHz operating frequency ▆ Single-cycle multiplication ▆ Integrated Nested Vectored Interrupt Controller (NVIC) ▆ 24-bit Sys Tick timer The Cortex®-M0+ processor is a very low gate count, highly energy efficient processor that is intended for microcontroller and deeply embedded applications that require an area...
