Can you give more information? Atmel Corporation makes no warranty for the use of its products, other than those expressly contained in. Also be aware that the A0 to A2 pins on the device package are meant to remain static in a design.
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.
So for example you keep A0: In figure 4 they refer to the address as an 8-bit quantity:. Post as a guest Name.
Are you being confused by the common mistake that many people make where they treat the address of an I 2 C wrongly? You do not write 24c40 addresses; you hardwire them. It will answer to address that was set up before powering up.

If a total of eight 24C02’s are used in the design then each of the devices will have these three pins hard strapped in a different combination from the set of b, b, b, b, b, b, b and b.
That’s why I said “write”. Then the address byte that you use to write to the third chip would be 0xA4 and the address byte for reading the second chip would be 0xA5. Atmel Corporation makes no warranty for the usedetailed in Atmel ‘s Terms and Conditions located on the Company’s web site.
No license, express or implied, by estoppel or otherwise, to any. Previous 1 2 In figure 4 they refer to the address as an 8-bit quantity: TurboJ The chip says the following: But my suggestion would to directly connect them to ground or VCC for 240c4 addressing scheme. Is there something else I need to do? RoomJapan Atmel Japan K. The device will not respond to the address that is being set dynamically. Atmel Corporation makes no warranty for the. This output is from I2C scanner.
I will try in about an hour.
Even the data sheet that you linked can lead to confusion in this regard. The information in this document is provided in connection with Atmel.

Email Required, but never shown. In Arduino, the function that does this is digitalWrite. 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.
Please refer to AT24C08A. Atmel Corporation makes no warranty for the use. 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 order for the device to be selected. If you just have one 24C02 then you would connect all three of those pins to GND as b.

The information in this document is provided in connection with Atmel products. 24c004 abstract text available Text: Can you explain what hardwiring is? 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.
