Product Introduction:

  This development board is made based on the CH552 chip. It supports a maximum system main frequency of 24MHz, and has a built - in 16K program memory ROM, 256 - byte internal iRAM, and 1KB on - chip xRAM. The xRAM supports DMA direct memory access. The CH552 has built - in functional modules such as ADC (Analog - to - Digital Conversion), touch - key capacitance detection, 3 groups of timers, signal capture and PWM (Pulse - Width Modulation), dual asynchronous serial ports, SPI (Serial Peripheral Interface), USB device controller and full - speed transceiver, Type - C, and USB.

 Enhanced 8051 core: It is an enhanced E8051 core single - chip microcomputer compatible with the MCS51 instruction set. 79% of its instructions are single - byte and single - cycle instructions, and the average instruction execution speed is 8 - 15 times faster than the standard MCS51. It has a unique XRAM data fast - copy instruction and supports a maximum system main frequency of 24MHz.

Built - in Flash/RAM: It has a built - in 16K program memory ROM, 256 - byte internal iRAM, and 1K - byte on - chip XRAM. The XRAM supports DMA direct memory access and has abundant peripherals.

USB: It has an embedded USB controller and USB transceiver, supporting USB 2.0 full - speed and low - speed host or device modes. It supports a maximum 64 - byte data packet, has a built - in FIFO, and supports DMA.

UART: It has 2 full - duplex asynchronous serial ports, both supporting high - baud - rate communication. UART0 is a standard MCS51 serial port.

Timer: It has 3 groups of timers/counters, supporting 2 - channel signal capture and 2 - channel PWM output.

SPI: It has 1 SPI communication interface, with a built - in FIFO and supporting Master/Slave modes.

ADC: It is a 4 - channel 8 - bit A/D analog - to - digital converter, supporting voltage comparison.

Touch: It has 6 - channel capacitance detection, supporting up to 15 touch keys and independent timing interrupts.
