I would like to interface a PIC18F452 to the SPI bus AT45DB041 Flash memory
. This is 3.3v part, but has all tolerant 5v input.
The PIC should be run at 40 Mhz, therefore I don't power it with 3.3v.

Do anyone have fact this?
I think to use a 74hct541 to translate the 3.3v input to 5v PIC. It is
necesary or the PIC can understand the 3.3v level ?

I wait help to solve this issue.

Thanks,
Sergio
