GENERAL DESCRIPTION
The Holtek HT32F1654/1653 devices are high performance, low power consumption 32-bit microcontrollers based around an 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 which includes advanced debug support. The devices operate at a frequency of up to 72MHz with a Flash accelerator to obtain maximum efficiency. They provide up to 64KB of embedded Flash memory for code/data storage and 16KB of embedded SRAM memory for system operation and application program usage. A variety of peripherals, such as ADC, I2C, USART, UART, SPI, I2S, PDMA, GPTM, MCTM, SCI, EBI, CRC16/32, USB2.0 FS, SW-DP (Serial Wire Debug Port), etc., are also implemented in the devices. 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 abo...
