Introduction

Overview

This user manual provides detailed information including how to use the devices, system and
bus architecture, memory organization and peripheral instructions. The target audiences for this
document are software developers, application developers and hardware developers. For more
information regarding pin assignment, package and electrical characteristics, please refer to the
datasheet.
The devices are high performance and low power consumption 32-bit microcontrollers based
around an Arm
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, I
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.
