Re: MT7628DAN data?

mango, great thanks for reply.
Some more questions:
What is the value of DDR_VCC? Is it 1.8V as usual for DDR2?
Is some termination needed for address/data pins or I can just leave it unconnected?
What is operating temperature range for MT7628DAN? Is it industrial?
For the number of reasons 7688AN+DDR2 chip is not a good option for my purposes.

Yes,1.8V, just use 7688 LDO(in chip) power it.
no need any termination ,just leave it float.

Thanks! Seems like I got enough information to start my design.

Ambient temperature: -20 ~ +55 ℃

Generally speaking, this is not so bad.

MediaTek's agent said that the chip shipment is not large, so the price is not very satisfactory.

Yes, MT7628/7688 slightly outdated now, 1000Mbit LAN is a requirement now for most applications. I don't speak for WiFi,
as it "no-no" for industrial usage.
