[WCH](http://www.wch.cn/)：[MCS-51](https://github.com/SoCXin/MCS-51)\r\n* [L1R1](https://github.com/SoCXin/Level)：24 MHz\r\n\r\n## [简介](https://doc.soc.xin/CH552)\r\n\r\n[CH552](http://www.wch.cn/products/CH552.html) 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 Flash，1K xRAM(支持DMA) +256B iRAM，128B DataFlash。\r\n\r\n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。\r\n\r\n### 关键参数\r\n\r\n* 24 MHz MCS-51 Core\r\n* 256B IRAM + 1KB SRAM + 14KB FLASH + 128B EEPROM\r\n* 5V-\u003e3.3V LDO\r\n* 2KB BootLoader，支持USB和串口ISP\r\n* Type-C 主从检测\r\n* USB device fs\r\n* UART x 2 + SPI x 1\r\n* 小封装 (TSSOP20/SOP16/MSOP10/QFN16)\r\n\r\n##

[选型建议](https://github.com/SoCXin/PL51RC003)\r\n\r\n[CH552](https://item.szlcsc.com/112593.html) 在USB应用领域拥有较高的人气，低阶高性价比的USB单片机。可以使用平台[platform-wch51](https://github.com/OS-Q/platform-wch51)进行开发，支持官方库和arduino\r\n\r\n所属同系列中[CH554](https://github.com/SoCXin/CH554) 增加支持USB HOST主机模式。[CH551](http://www.wch.cn/products/CH551.html)的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。\r\n\r\n相较[STM8S003](https://github.com/SoCXin/STM8S003) 及 [N76E003](https://github.com/SoCXin/N76E003) 系列产品，[CH552](https://github.com/SoCXin/CH552)缺少IIC硬件，ADC较弱，没有专门的 eeprom存储器。TSSOP20封装不兼容前两者，无法直接替换。\r\n\r\n##
