32-Bit ARM® Cortex™-M0+ MCU
HT32F52231/HT32F52241/HT32F52331/HT32F52341
General Description
1
The HOLTEK HT32F522x1/523x1 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 40MHz for HT32F52231/52241 and 48MHz for
HT32F52331/52341 with a Flash accelerator to obtain maximum efficiency. It provides up to
64KB of embedded Flash memory for code/data storage and 8 KB of embedded SRAM memory
for system operation and application program usage. A variety of peripherals, such as ADC, I2C,
USART, UART, SPI, MCTM, GPTM, SCTM, CRC-16/32, RTC, WDT, SCI, USB2.0 FS, 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.
