HT32F50220 Datasheet | Holtek Semiconductor

Description The Holtek HT32F50220/HT32F50230 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 to obtain maximum efficiency. It provides up to 32 KB of embedded Flash memory for code/data storage and 4 KB of embedded SRAM memory for system operation and application program usage. A variety of peripherals, such as Hardware Divider DIV, ADC, I2C, UART, SPI, GPTM, PWM, BFTM, RTC, WDT, 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. 1 General Description Rev. 1.50 6 of 42 September 01, 2025 2 Features 32-Bit Arm® Cortex®-M0+ MCU HT32F50220/HT32F50230 2 Features Core ▆ 32-bit Arm® Cortex®-M0+ processor core ▆ Up to 20 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 optimized, low-power processor. The processor is based on the ARMv6-M architecture and supports Thumb® instruction sets, single-cycle I/O ports, hardware multiplier and low latency interrupt respond time.
