Apparently, there should perhaps be some time between available and receive Check your chips markings. That’s why I said “write”. Instead the three bits that you supply out on the interface in the device address field must match the hard strapped values on the pins in 24×02 for the device to be selected.

Serial EEPROM AT24C02

Is there something else I need to do? On top of that I have never been sure that it is even possible to dynamically change the strapped value on the A0, A1 and A2 pins of a 24C02 after it has powered up. Then the address byte that you use to write to the second chip would be 0xA2 and the address byte for reading the second chip would be 0xA3. Vcc enables write protection. Can you explain what hardwiring is?


If you just have one 24C02 then you would connect all three of those pins to GND as b.
