24C32 – 24C32 4k x 8 Serial CMOS EEPROM

The data sheet for the eeprom states that it uses a “byte” size variable. There are some smart folks here tho, and they should be able to help you out. Members who have read this thread: If you can’t get it working, check the MCP sheet for the pic, and look for the register settings for the IC This allowed correct excecution but I don’t know if it was the real cause.

My whining goes here.


There’s no problem, only learning opportunities. My program just keeps saying it is failing. I got data back on I2C from the 18F!

Steve It’s not a bug, it’s a random feature. Hi Tom, Yup, I learned about those address bits recently. It took me 2.

Different 24c23wp thebut perhaps some of what I just figured out will help you By physically connecting A0, A1, A2 in the case of the 24LC anywayone sets up an address for each chip so it can be referenced on the I2C bus Join Date Jul Posts 2, Results 1 to 13 of I don’t know if this is rigth or not, but it seems to be working. I have the same problem you are having – no I2C data!! Maybe this update will help out going forward. Also tried pulling W pin on 24C32 to gnd, using another eeprom, tried with 24C64, still no luck.

Like Mulder always said in the X-Files “the answer is out there Have you added a ‘failed’ lable routine to the I2Cread or write command so you can tell if it is failing.? Join Date Sep Posts 2. I am using 24LC units, I have two chips wired for addressing as follows: Problem with I2C 2c432wp eeprom.


It seems neither writing or reading work. I have a similar issue, but have an idea that might help a little. It would only take a line to explain that the Control byte always starts In your case, yes indeed, Address variable [B0] must be a Word sized variable.

The time now is A small town called Denmark. The MELAb dagasheet defines the variable properly. If I still have some of the above wrong – please reply.

What should I try next? I2c Melanie, Thanks very much for taking the time to reply in full.
