Posted - 03/25/2013 : 08:18:19 I am trying to replace a damaged CSI 24C01BJ EEPROM in an old system.
The problem is that the data is not readable on a new chip in the old system.
I can read the data and write the data to the old chips and install them into the old system and it works perfectly.
I can write the data to a new chip and it will not read when installed in the old system.
I can only read the data on the new chip with the USB programmer. Using GQ-4X with latest software downloaded from this site.
I have tried the following 2 new chips: AT24C01BN-SH-T CAT24C01WI-GT3
I have tired different write speeds also.
I need to be able to install a new chip to replace damaged or corroded ones that get returned from the field.
Why can I read and write to an old original chip, but cant read the data back from a new chip when installed into the system????
Thanks |

Posted - 03/27/2013 : 13:05:48 your system needs specific brand of chip. It is your old system cmpatibility problem. It is not universal.
Try to buy exact chip of your old chip. |
