SPI 5V to 3V3
Have you considered using a mega128L and running it at 3.3V? The only downside is that the maximum specified clock speed is 8MHz. Dave.

Serial Dataflash Problem
Problem Solved!!! :P I noticed that the 3.3V supply wasn't looking too great during memory transfers. So I added a 2.2uF cap along with the 100nF decoupling cap. Now that supply...

I've now tried it at 8MHz /128. Still the same problem.... :?

Serial Dataflash Problem
According to the datasheets, the maximum clock frequency is 20MHz. Im running the AVR with an 8MHz crystal (/2), so I don't think that should be a problem. There's no harm in...
