## [CH552简介](https://github.com/SoCXin/CH552/wiki)
[CH552](https://github.com/SoCXin/CH552)兼容MCS51的增强型E8051内核79%指令是单字节单周期指令2KB BootLoader + 14KB Flash1K xRAM(支持DMA) +256B iRAM128B DataFlash。
内置24MHz时钟源和PLL内置了ADC模数转换、触摸按键电容检测、3组定时器和信号捕捉及PWM、双异步串口、SPI、USB设备控制器和全速收发器、USB type-C等功能模块。

### [选型建议](https://github.com/SoCXin)
[CH552](https://github.com/SoCXin/CH552) 是市场上高性价比USB单片机在开源社区中拥有较高声望。
同系列中升级[CH554](http://www.wch.cn/products/CH554.html)将增加支持USB HOST主机模式
降低规格可选[CH551](http://www.wch.cn/products/CH551.html)ROM降为10K片内xRAM为512字节异步串口仅提供UART0仅SOP16封装并且去掉了ADC模数转换模块和USB type-C模块。
