除了成本之外，从DP83848C切换到LAN8740A的理由是什么？

你要建多少块木板？成本，设备大小，电缆诊断，局域网上的Wake，列表之一。节省成本是巨大的。DP838 8C在1K PC上的价格大约是3美元，对于1LK的PC来说，0.76美元是0.76美元，如果你正在建造不到1000个板，并且原型和软件已经准备好了，我会把DP838 48 C放在适当的位置。如果我正在建造超过10000个板或者需要旋转板，LAN810A将被使用。（近引脚PIN兼容LAN840A，但没有EEE，WOL，电缆诊断）。App注意详细说明迁移LAN810A到LAN840A（使电路板接受任何设备，所以当市场说我们需要在空闲模式下节省电力，你已经有电源PMIC和NIN准备好WAK在局域网上）。



      以下为原文

    How many boards are you building?
 
Cost, Device Size, Cable Diagnostics, Wake on LAN, list goes one.  Cost savings is huge. The DP83848C was something like $3.00 in 1K pc vs $0.76 in 1K pcs for LAN8710A
 
If you are building less than 1,000 boards and prototype and software is ready to go; I'd leave the DP83848C in place.
 
If I was building more than 10,000 boards or needed to spin the board, the LAN8710A would be used. (near pin for pin compatible with the LAN8740A, but doesn't have EEE, WoL, Cable Diagnostics).
 
App Note detailing migrating LAN8710A to LAN8740A (make the board accept either device, so when marketing says we need save power in idle mode, you already have the power supply PMIC and nINT ready for Wake on LAN).

谢谢你的回复。实际上它没有这么多的音量。事实上，和声仍然支持DP，所以我想我会坚持下去。

    Thanks for your response. It's actually not that much volume. In fact Harmony still suports the DP, so I guess I'll stick with it.

大小和包装也一样。8740是较小的，其在QFN，VQFP。QFN比QFP更适合自动化布局。



      以下为原文

    Also size and package.  The 8740 is smaller, its in a QFN, vs QFP.     QFN's are considerably more relaible than QFP's for automated placement.
 
 

事实上，配售不是问题。MY-500和G20；M20-＆GT；BCl609眨眼：

    Indeed, placing is not a problem though. MY500->M20->BCL609 wink:
