Cortex-M3, 72 MHz
The HOLTEK HT32F125x series of devices are high performance, low power consumption 32-bit microcontrollers based on the Arm Cortex-M3 rocessor core. The Cortex-M3 is a next-generation processor core which is tightly coupled with a Nested Vectored Interrupt Controller (NVIC), SysTick timer and advanced debug support.
The HT32F125x device operates at a frequency of up to 72MHz with a Flash accelerator to obtain maximum efficiency. It provides up to 32KB 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 ADC, I2C, USART, SPI, SW-DP (Serial Wire Debug Port), etc., are also implemented in this device series. Several power saving modes provide the flexibility for maximum optimisation between wakeup latency and power consumption, an especially important consideration in low power applications.
The above features make the HT32F125x device suitable for a wide range of applications, especially in areas such as white goods and application control, power monitor and alarm systems, consumer and handheld equipment, data logging applications and so on.
