HT32F1654 Description

Short technical summary and product information.

The HOLTEK HT32F1654 is a high-performance, low-power 32-bit microcontroller built around the Arm Cortex-M3 processor core. This core is tightly integrated with a Nested Vectored Interrupt Controller (NVIC) and SysTick timer, providing advanced debug support and efficient interrupt handling.

 

The device operates at frequencies up to 72 MHz, enhanced by a Flash accelerator for optimal performance. It includes up to 256 KB of embedded Flash memory for code and data storage, alongside 32 KB of embedded SRAM for system operations and application programs. A wide array of peripherals such as ADC, I2C, USART, UART, SPI, I2S, PDMA, GPTM, MCTM, SCI, EBI, CRC-16/32, and USB2.0 FS are implemented.

 

Multiple power-saving modes allow for flexible optimization between wake-up latency and power consumption, making it suitable for low-power applications. These features enable the HT32F1654 to be used in diverse applications including white goods control, power monitors, alarm systems, consumer products, handheld equipment, data logging, motor control, and fingerprint recognition.
