When you say that you are “writing” to the pins this does not make clear exactly what you are doing. 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.
Atmel Corporation makes no warranty for the. Atmel Corporation makes no warranty for the use. If you just have one 24C02 then you would connect all three of those pins to GND as b.

This device is not recommended for new designs. Please refer to AT24C08A. Email Required, but never shown. Atjel 6 This output is from I2C scanner. It connects the SOT package pins to the same signal position of the 8 pin DIPmechanical and electrical connections are supported by this adapter.
Then when you want to write to the part use an address byte of 0xA0 and when you want to read use an address byte of 0xA1.
