Hello, I am working on building a small and simple data collector.
Basically, the circuit is going to have a Microchip 8-bit uC and
a serial EEPROM. The circuit is going to be powered using a 3V
coin cell with the positive terminal connected to the VDD of both
chips and the negative terminal connected to the VSS of both chips.
Suppose that I (or somebody using my circuit) screws up and puts
the coin cell in backwards. Do you think that irreversible damage
will occur to either the uC or the serial EEPROM? How should I
put a diode into the circuit if damage will occur? How do I choose
the diode?
Thank you for any help or insight you can provide.
