HT32F52234/HT32F52244 Datasheet 32-Bit Arm® Cortex®-M0+ Microcontroller, up to 64 KB Flash and 8 KB SRAM with 1 Msps ADC, DAC, USART, UART, SPI, I2C, PWM, SCTM, BFTM, CRC, UID, DIV, PDMA, RTC and WDT Revision: V1.10 Date: December 03, 2024 32-Bit Arm® Cortex®-M0+ MCU HT32F52234/HT32F52244 1 General Description The Holtek HT32F52234/HT32F52244 devices are high performance, low power consumption 32bit 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 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 Hardware Divider DIV, PDMA, ADC, DAC, I2C, USART, UART, SPI, BFTM, SCTM, PWM, CRC-16/32, 96-bit Unique ID, 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 control, power monitors, alarm systems, consumer products, handheld equipment, data logging applications, motor control and so on. 1 General Description Rev. 1.10 6 of 46 December 03, 2024 2 Features 32-Bit Arm® Cortex®-M0+ MCU HT32F52234/HT32F52244 2 Features Core ▆ 32-bit Arm® Cortex®-M0+ processor core ▆ Up to 60 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...
