I have a circuit that is using a PIC18f452 micro operating at 5 volts. I need to be able to communicate with a MAX31855 via SPI. My micro (because of other devices needs) operates on 5 volts but the MAX31855 at 3.3. What is the workaround for talking to devices operating at lower voltages? Will the MAX31855 blow up it I connect the comm pins directly to 5 volt logic and power it from 3.3?
Thanks for your thoughts,
