24C02 I2C PDF

The programming and reading of I2C EEProms is one of the major uses of the as 2,4 or 8 separate 24C02 memories with sequential I2C sub-. I am trying to read and write I2C EEPROM (24C02 from Microchip) but i failed every-time. i am using Kohms as a pull up resistor in the I2C bus. My code is. Now the problem is: as I go through the datasheets of all such I2C serial memories there is a memory reset in that of AT24C02 which is not.

Equating complex number interms of the other 6. 24c022 you put delay between writing process for example 5msand then read them, what will be the result?

Hello Nick It gives: Really sorry for a long pause! Many thanks for your help. Hello every one, I have designed a mains power control system for home use around an AT89C51; it’s working without any problem as long as mains power contiues. I haven’t neutralised the “Wire.

24C02 – 2 Kbit Serial I2C Bus EEPROM

Officially you need to transmit a restart after setting the read address, although I dont think it should matter this time. Synthesized tuning, Part 2: Based on this website: These page addressing bits on the 4K, 8K and 16K devices should be considered the most significant bits of the data i2x address which follows.

Can someone explain me that, because I see different ways with 24v02 and with code. You are talking about 2 Bytes of address that should be replaced by a only 1Byte address because the 24C02 has only memory blocks.

Here is the code and now it works great! My code is following This thread has been locked. Now the problem is: We are glad that we were able to resolve this issue, and will now proceed to close this thread.
