[CH554](https://github.com/SoCXin/CH554)\n\n[![sites](http://182.61.61.133/link/resources/SoC.png)](http://www.SoC.Xin)\n\n[![Build Status](https://github.com/SoCXin/CH554/workflows/CI/badge.svg)](https://github.com/SoCXin/CH554/actions/workflows/CI.yml)\n\n* [WCH](http://www.wch.cn/): [8051](https://github.com/SoCXin/8051)\n* [L1R1](https://github.com/SoCXin/Level): 16/24 MHz\n\n### [简介](https://github.com/SoCXin/CH554/wiki)\n\n[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。\n\nCH554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。\n\n[![sites](docs/CH554.png)](http://www.wch.cn/products/CH554.html)\n\n#### 关键特性\n\n* USB 2.0 FS (H or D)\n* 5V-\u003e3.3V LDO\n* 128B DataFlash\n* USB Type-C 主从检测\n* 内置2KB BootLoader，支持USB和串口ISP\n\n### [资源收录](https://github.com/SoCXin)\n\n* [参考资源](src/)\n* [参考文档](docs/)\n* [参考工程](project/)\n\n### [选型建议](https://github.com/SoCXin)\n\n[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。\n\n* [CH552](http://www.wch.cn/products/CH552.html)不支持USB-HOST主机模式\n* [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。\n\n* 各种小封装可选：TSSOP20/SOP16/QFN16/MSOP10\n\nCH554/CH552具有Type-C CC功能，更多[WCH
