HT32F54231/HT32F54241 HT32F54243/HT32F54253 32-Bit Arm® Cortex®-M0+ 5V Touch Microcontroller, up to 128 KB Flash and 16 KB SRAM with 1 Msps ADC, Touch Key, DIV, CMP, USART, UART, SPI, I2C, GPTM, SCTM, BFTM, MCTM, PDMA, LED Controller, CRC, RTC and WDT Revision: V1.50 Date: September 04, 2025 32-Bit Arm® Cortex®-M0+ 5V Touch MCU HT32F54231/HT32F54241/HT32F54243/HT32F54253 1 General Description The Holtek HT32F54231/HT32F54241/HT32F54243/HT32F54253 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 60 MHz with a Flash accelerator to obtain maximum efficiency. It provides up to 128 KB of embedded Flash memory for code / data storage and up to 16 KB of embedded SRAM memory for system operation and application program usage. A variety of peripherals, such as Hardware Divider DIV, PDMA, ADC, I2C, USART, UART, SPI, GPTM, SCTM, BFTM, MCTM, CRC-16/32, RTC, WDT, Touch key, LED controller and SW-DP (Serial Wire Debug Port), etc., are also implemented in the device series. 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 washing machines, refrigerators, electric pressure cookers, high-speed blenders, rice cookers and so on. 1 General Description Rev. 1.50 6 of 56 September 04, 2025 2 Development Tools 32-Bit Arm® Cortex®-M0+ 5V Touch MCU HT32F54231/HT32F54241/HT32F54243/HT32F54253 2 Development Tools For rapid product development and to simplify device parameter setting, Holtek has provided relevant...
