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.

Hello Sagar, Seems that still nobody can help you in your case random read and write-read multiple bytes. I will share you my i2c code using 24LC, it is very simple and doesn’t use interrupt, so it is easier to follow the flow. I got the expected data. I’m doing my first step working with I2C Eeprom and I can’t get it working.
