Cortex-M3, 72 MHz
The HOLTEK HT32F1755/1765/2755 devices are high performance and low power consumption 32-bit microcontrollers based around an Arm Cortex-M3 processor core. The Cortex-M3 is a next-generation processor core which is tightly coupled with Nested Vectored Interrupt Controller (NVIC), SysTick timer, and including advanced debug support.
The HT32F1755/1765 devices operate at a frequency of up to 72MHz with a Flash accelerator to obtain maximum efficiency. It provides 128KB of embedded Flash memory for code/data storage and up to 64KB of embedded SRAM memory for system operation and application program usage. A variety of peripherals, such as ADC, I2C, USART, SPI, PDMA, GPTM, MCTM, SCI, CSIF, USB2.0 FS, SWJ-DP (Serial Wire and JTAG Debug Port), etc., are also implemented in the 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 ensure that the HT32F1755/1765/2755 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, fingerprint recognition and so on.
