The HOLTEK HT32L52231/52241 devices are high performance, ultra-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 48 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 PDMA, Hardware Divider DIV, ADC, I2C, USART, UART, SPI, MCTM, GPTM, SCTM, CRC-16/32, RTC, 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 ultra-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 handheld devices, personal medical devices, home automation, industrial sensors and so on.
