Because in the past, I just look at the CY...18, so I am quite sure that my Lan Card project can be finished by using it. However, I found that the price of the CY..18 is quite expensive and will make me over budge, so I need to give up that chip. Luckly, a tutor tell me I can use AN2131 with the some function like CY..18, so I read the datasheet of it and want to confirm whether the chip can work.


Recently, I bought some of the AN2131, but it need DDK to before I download program to it, but my deadline is coming.................The DDK for WindowXP need to time to ship.............so bad now.........
