24C04SMD – 24C04 Datasheet

Tamel The chip says the following: Sign up or log in Sign up using Google. Sign up using Email and Password. In figure 4 they refer to the address as an 8-bit quantity:. So for example you keep A0: Email Required, but never shown.

Sign up using Facebook. However, it doesn’t matter what I set these pins to. But my suggestion would to directly connect them to ground or VCC for the addressing scheme. Check atmep chips markings. Atmel Corporation makes no warranty for the. A2 are used for creating the address.

Atmel Corporation makes nowarranty which is detailed in Atmel ‘s Terms and Conditions located on the Company’s web site. Post as a guest Name. Normally there is no writing to the 24C02 pins.

The information in this document is provided in connection with Atmel. It will answer to address that was set up before powering up. No license, express or implied, by estoppel or otherwise, to any. In Arduino, the function that does this is digitalWrite. The device will not respond to the address that is being set dynamically.

In figure 4 they refer to the address 24cc04 an 8-bit quantity: Atmel Corporation makes no warranty for the usedetailed in Atmel ‘s Terms and Conditions located on the Company’s web site. It connects the SOT package pins to the same signal position of the 8 pin DIPmechanical and electrical connections are supported by this adapter. Previous 1 2 Please refer to AT24C08A. Can you explain what hardwiring is?

When you say that you are “writing” to the pins this does not make clear exactly what you are doing. Can you give more information?


That’s why I said “write”. The information in this document is provided in connection with Atmel products.

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 2c404 be 0xA2 and the address byte for reading the second chip would be 0xA3.

If you just have one 24C02 then you would connect all three of those pins to GND as b. Then when you want to write to the part amtel an address byte of 0xA0 and when you want to read use an address byte of 0xA1.

You do not write the addresses; you hardwire them. Even the data sheet that you linked can lead to confusion in this regard. By using our site, you acknowledge that you have read and understand our Cookie PolicyPrivacy Policyand our Atmsl of Service.
