GENERAL DESCRIPTION

The Holtek HT32F125x series of devices are high performance, low power consumption 32-bit microcontrollers based on the ARM® Cortex™-M3 processor core. The Cortex™-M3 is a nextgeneration processor core which is tightly coupled with a Nested Vectored Interrupt Controller (NVIC), SysTick timer and advanced debug support. A variety of peripherals, such as ADC, I2C, USART, SPI, SW-DP (Serial Wire Debug Port), etc., are also implemented in this device series. Several power saving modes provide the lexibility for maximum optimisation between wakeup latency and power consumption, an especially important consideration in low power applications.
