CH554G USB Microcontroller Development board

Description

Development board for theCH554G low-cost 8-bit 8051 core microcontrollers with native USB 2.0 and Arduino IDE support. Overview The CH55x is an 8-bit enhanced E8051 core MCU compatible with the MCS51 instruction set. 79% of its instructions are single-byte single-cycle instructions, and the average instruction speed is 8 – 15 times faster than that of the standard MCS51. The special xRAM supports direct memory access (DMA), data fast copy command, and double DPTR pointers. The CH55x has a built-in USB controller and USB transceiver, it supports USB-Host mode and USB-Device mode (all), USB 2.0 full-speed (12Mbps) and low-speed (1.5Mbps) traffic, data packets of up to 64 bytes, and DMA. It has a factory built-in bootloader so firmware can be uploaded directly via USB without the need for an additional programming device. Product Description -Built-in Flash/RAM Built-in 16KB program memory ROM, 256 bytes internal iRAM and 1KB on-chip xRAM, which supports DMA direct memory access -USB : Embedded USB controller and USB transceiver, supporting USB2.0 full speed and low speed host or device mode. Support up to 64-byte data packet, built-in FIFO, support DMA -UART: 2 full-duplex asynchronous serial ports, both of them support high baud rate communication. UART0 is a standard MCS51 serial port -Timer: 3 groups of timers/counters, supporting 2 signal capture and 2 PWM output -SPI: 1 SPI communication interface, built-in FIFO, support master-slave mode -ADC: 4-channel 8-bit A/D analog-t
