HT32F50231/HT32F50241 Datasheet 32-Bit Arm® Cortex®-M0+ 5V Microcontroller, up to 64 KB Flash and 8 KB SRAM with 1 Msps ADC, DIV, USART, UART, SPI, I2C, MCTM, GPTM, BFTM, PWM, CRC, RTC and WDT Revision: V1.50 Date: August 25, 2025 32-Bit Arm® Cortex®-M0+ 5V MCU HT32F50231/HT32F50241 1 General Description The Holtek HT32F50231/50241 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 20 MHz with a Flash accelerator to obtain maximum efficiency. It provides up to 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 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 controllers and so on. 1 General Description Rev. 1.50 6 of 44 August 25, 2025 32-Bit Arm® Cortex®-M0+ 5V MCU HT32F50231/HT32F50241 2 Development Tools For rapid product development and to simplify device parameter setting, Holtek has provided relevant development tools which users can download from the following link: https://.holtek./page/tool-detail/dev_plat/Illumination/DALI_workshop Features 2 Development...
