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.

The A0, A1 and A2 pins are no connect. Choosing IC with EN signal 2. Trademarks Privacy Policy Terms of Use. A read operation is initiated if this bit is high and a write operation is initiated if this bit is low. Hello every one, I have designed 24c022 mains power control system for home use around an AT89C51; it’s working without any problem as long u2c mains power contiues.

Really sorry for a long pause! The A2 bit must compare to its corresponding hard-wired input pin.

Negative acknowledge is done by inverting acknowledge polarity. The interesting thing that you should try is to put delay.

So I think, you might be talking about something that has to do with this. If a compare isnot made, the chip will return to a standby state.
