  HT32_DFP

The Holtek HT32F620xx are high performance, low power consumption 32-bit microcontrollers based around an Arm Cortex-M0+ processor core. The Cortex®-M0+ is a next-generation processor core which is tightly coupled with Nested Vectored Interrupt Controller (NVIC), SysTick timer, and including advanced debug support.

The devices operate at a frequency of up to 40 MHz for HT32F620xx with a Flash accelerator to obtain maximum efficiency. It provides up to 128 KB of embedded Flash memory for code/data storage and 16 KB of embedded SRAM memory for system operation and application program usage. A variety of peripherals, such as ADC, DIV, PDMA, I2C, USART, UART, SPI, MCTM, GPTM, SCTM, CRC-16/32, RTC, WDT, SW-DP (Serial Wire Debug Port), etc., are also implemented in the device series. Several power saving modes provide the flexibility for maximum optimization between wakeup latency and power consumption, an especially important consideration in low power applications.

The device has an integrated smoke detector, including smoke detector AFE, two programmable constant current channels. The controller communicates via one-wire interface.

The above features ensure that the device is suitable for use in the smoke detector applications.
