32-Bit ARM® Cortex™-M0+ MCU

HT32F52220/HT32F52230

1 General Description

The HOLTEK HT32F52220/52230 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), SysTick timer, and including advanced debug support.

The devices operate at a frequency of up to 40 MHz for HT32F52220/52230 with a Flash

accelerator 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 ADC, I2C, USART, UART, SPI, GPTM, SCTM,

BFTM, WDT, 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 white goods application control, power monitors, alarm systems,

consumer products, handheld equipment, data logging applications, motor control and so on.
