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。
