[芯片简介](https://github.com/SoCXin/RP2040/wiki)\n\n[RP2040](https://www.raspberrypi.com/products/raspberry-pi-pico/) 是一款Cortex M0+ 双核MCU，运行频率为 133 MHz (极端情况下可超频到1GHz)\n\n[![sites](docs/RP2040.png)](https://www.raspberrypi.com/documentation/microcontrollers/rp2040.html)\n\n### 关键特性\n\n* 133MHz Cortex-M0+ Dual Core\n* 264KB RAM + 256KB Flash + 16MB

[工程模板](templates/)\n\n软件开发可使用平台[platform-rp2040](https://github.com/OS-Q/platform-rp2040)\n\n## [选型建议](https://github.com/SoCXin)\n\n2021年1月发布的[RP2040](https://item.szlcsc.com/2392.html)包含两个子系列:\n\n* 支持USB的RP2040xxU系列\n* 不支持USB的RP2040xxN(1.8V-3.6V)/RP2040x4NR(1.8V-5.5V)\n\n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。\n\n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。\n\n\nRP2040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。\n\n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。\n\n[![sites](docs/xin.png)](https://www.raspberrypi.com/documentation/microcontrollers/rp2040.html)\n\n\n### 开源方案\n\n*
