5V Wide Voltage Arm® Cortex®-M0+ 32-bit MCUs

09/12/2022

The HT32F50020/HT32F50030 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 16 MHz with a Flash accelerator to obtain maximum efficiency. It provides up to 32 KB of embedded Flash memory for code/data storage and 2 KB of embedded SRAM memory for system operation and application program usage. A variety of peripherals, such as ADC, I2C, UART, SPI, SCTM, BFTM, LEDC, RTC, WDT and SW-DP (Serial Wire Debug Port), etc., are also implemented in the devices. Several power saving modes provide the flexibility for maximum optimization between wakeup latency and power consumption, an especially important consideration in low power applications.
