* [WCH](http://www.wch.cn/)[E8051](https://github.com/SoCXin/8051)
* [L1R1](https://github.com/SoCXin/Level)24 MHz
## [简介](https://doc.soc.xin/CH552)
[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。
#### 关键特性
* 5V->3.3V LDO
* 2KB BootLoader支持USB和串口ISP
* Type-C 主从检测
* USB device fs
* UART x 2 + SPI x 1
* 小封装 (TSSOP20/SOP16/MSOP10/QFN16)

### [选型建议](https://github.com/SoCXin)
[CH552](https://github.com/SoCXin/CH552) 在8051领域拥有较高的声望低阶高性价比USB单片机。
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。
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。
