Is Atmel dataflash 5v safe?

Started by Tim Mitchell April 8, 2005
Despite scouring the datasheet, I cannot find the answer to this 
question:
Can you safely apply 5V inputs to Atmel Dataflash devices? (vcc=2.7V)

It quotes the "Absolute Max input voltage" as 6.25V, so presumably it 
won't blow up, but will it work?

I'm using a 5V processor and would rather like to not get involved in 
lots of level shifting.

I am using AT45DB041 in a 5V system. It is designed to withstand 5V on inputs... All works flawlessly... regards Dejan

Atmel's document DOC3297 describes using 3V Dataflash devices in 5 volt systems. regards David
