## [选型建议](https://github.com/SoCXin)
2021年1月发布的[RP2040](https://item.szlcsc.com/2392.html)包含两个子系列:
* 支持USB的RP2040xxU系列
* 不支持USB的RP2040xxN(1.8V-3.6V)/RP2040x4NR(1.8V-5.5V)采用TSMC 40nm制程工艺,芯片带有4ch 12-bit 500Ksps ADC,精度优于ESP32,可替换ATmega328p,广泛应用于各种外设驱动和通用控制场景。
性价比非常高,价格介于[STM32G030C8T6(¥4.14)](https://item.szlcsc.com/549607.html)和[STM32G070RBT6(¥5.07)](https://item.szlcsc.com/549618.html)之间,开源资源丰富,在Arduino和Micropython等生态资源上拥有无与伦比的优势。
RP2040中有2个相同的PIO块,每个PIO块都有专用的连接到总线结构,GPIO和中断控制器,每个块有四个状态机,可以独立执行顺序程序来操作GPIO和传输数据。
与通用处理器不同的是,PIO状态机对IO的专业化程度很高(highly specialised),它注重确定性,精确的时序,并与固定功能硬件紧密结合。PIO状态机可以动态地配置和重新配置,以实现许多不同的接口,自由度很高。
