# [CH554](https://github.com/SoCXin/CH554)
[](http://www.SoC.Xin)
[](https://github.com/SoCXin/CH554/actions/workflows/CI.yml)
* [WCH](http://www.wch.cn/): [8051](https://github.com/SoCXin/8051)
* [L1R1](https://github.com/SoCXin/Level): 16/24 MHz
### [简介](https://github.com/SoCXin/CH554/wiki)
[CH554](https://github.com/SoCXin/CH554) 增强型E8051内核,79%指令是单字节单周期指令,2KB Boot + 14KB Flash,1K xRAM(支持DMA) +256B iRAM,128B DataFlash。
CH554提供丰富的接口资源,包括ADC模数转换、3组定时器和信号捕捉及PWM、双异步串口、SPI等。6通道电容检测模块,互电容方式支持最多15个触摸按键。内嵌全速USB控制器,支持USB HOST主机模式和USB DEVICE设备模式。

#### 关键特性
* USB 2.0 FS (H or D)
* 5V->3.3V LDO
* 128B DataFlash
* USB Type-C 主从检测
* 内置2KB BootLoader,支持USB和串口ISP

### [选型建议](https://github.com/SoCXin)
[CH554](https://github.com/SoCXin/CH554)是一款广泛应用的低成本USB HOST MCU,降配版本[CH552](https://github.com/SoCXin/CH552)具有更高性价比,应用于各种简单USB通信外设,已经积累了不少的开源的项目,尤其是在开源硬件领域,用于在板调试。
* [CH552](http://www.wch.cn/products/CH552.html)不支持USB-HOST主机模式
* [CH551](http://www.wch.cn/products/CH551.html)ROM降为10K,xRAM为512字节,串口仅UART0,封装仅SOP16,去掉了ADC和USB type-C功能。
* 各种小封装可选:TSSOP20/SOP16/QFN16/MSOP10
CH554/CH552具有Type-C CC功能,更多[WCH PD](http://www.wch.cn/search?q=USB+PD&t=all)方案,以及关于[USB-PD](https://github.com/Qful/PD)

#### 完成度较高的开源项目
* [ch55xduino](https://github.com/DeqingSun/ch55xduino) 类arduino框架
* [ch554_sdcc](https://github.com/Blinkinlabs/ch554_sdcc) 基于SDCC的工程模板
