Is there something else I need to do? This device is not recommended for new designs. In 240c4 4 they refer to the address as an 8-bit quantity: TurboJ The chip says the following: Maybe the issue is setting the address after power on. Home Questions Agmel Users Unanswered. 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.
When you say that you are “writing” to the pins this does not make clear exactly what you are doing.
It connects the SOT atmsl pins to the same signal position of the 8 pin DIPmechanical and electrical connections are supported by this adapter. If you just have one 24C02 then you would connect all three of those pins to GND as b.
Please refer to AT24C08A. No abstract text available Text: Atmel Corporation makes no warranty for the. The information in this document is provided in connection with Atmel. So for atmwl you keep A0: Can you explain what hardwiring is?

2404 your chips markings. 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.

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.
It will answer to address that was set up before powering up. A2 are used for atel the address. Can’t change the values dynamically.
