Frequently asked questions
How do I wire the 93C46 to an Arduino?
Connect CS, SK (clock), DI (data in) and DO (data out) to digital pins, and connect VCC and GND. The ORG pin selects 8-bit or 16-bit organization.
Does the data stay saved when power is off?
Yes. EEPROM retains its contents without power, so stored settings remain after the board is switched off.
