About product and suppliers: Even the data sheet that you atmek can lead to confusion in this regard. Check your chips markings.
So for example you keep A0: Now, i was wondering, if i 2c404 program it using my arduino. 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.
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 ateml to be selected.
MaNyYaCk 6 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. Can you give more information?
Previous 1 2 Gin on Dec 12, I want to lessen the size of my projects, and with my research, the ATtiny 244c04 of uCs can be programmed by the arduino, and further reading has lead me that 24c4 PICAXE uCs can be programmed by the arduino as well. In figure 4 they refer to the address as an 8-bit quantity: However, it doesn’t matter what I set these pins to. There are 99 atmel 24c04 suppliers, mainly located in Asia.

Normally there is no writing to the 24C02 pins. The information in this document is provided in connection with Atmel products. Can you supply door to door installation service for machines 9 Answers: Do you get CE certified 9 Answers: It considers the value of the A0,A1 and A2 before the power up and sticks to it till reset.
Supplier Types Trade Assurance. If a total of eight 24C02’s are used in 42c04 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. You do not write the addresses; you hardwire them. It will answer to address that was set up before powering up.
Also be aware that the A0 to A2 pins on the device package are meant to remain static in a design.
