ATS2819/ATS2819P標準應用方案主要分為以下功能模塊：Power Supply，BlueTooth，Audio Input/Output（包括codec、I2C、SPDIF），FM Receiver，disaplay（LED&LCD），USB，SPI NOR Flash Memory，SD/MMC/MS Card等。1.2原理圖設計總體原則1原理圖設計需要按照方案規格的要求實現各項硬件功能，盡量避免功能模塊相互間的資源沖突。如果存在I/O復用，接收復用等情況，除了需注意檢查I/O上電狀態，接口時序等，還需要注意復用的SIO工作頻率與工作電壓域是否符合要求(如WIO)，確保功能設計正確實現。2原理圖設計要求性能達到要求。如穩定性，啟動電壓，功耗，ESD，EMI等。要注意檢查模塊電源開關狀態，選擇的原件標稱及精度、材質，接口保護元件和EMI濾波器等。3系統時鐘26MHZ，要求CL為7~9PF，精度為+-10PPM。這樣才能保證系統能正常工作。4當設計PCB受限于模具大小時，各個模塊無法保證均能得到最優的布局布線(如濾波電容要求靠近IC、走線上要求盡量少的過孔與盡可能短的走線)。因為在此給出一個模塊優先級以供設計人員參考，從而提高方案設計的效率，增加一版work的可行性。將優先級以阿拉伯數據排列
