93C56 Datasheet, PDF – Alldatasheet

I just wonder if moving the chip might be a solution. Ill see what I can do about separating that chip. There must be a procedure to clone the new cluster from the old. I just figured why not try with my arduino and learn a thing or two. I’ll 93cc56 if I can find my old bitbasher – but given the datasheet you could figure it out.

If you had the appropriate sw from the manufacturer I bet you could do this via the OBDII connector – but I also bet they’re not telling you how! Writing to the eeprom isn’t too hard if you have access to the pins. And if so how would I go about doing this? It may be cheaper and less risky to go to a Cherokee dealer and get datashewt to do it It won’t be easy, as they don’t want crooks ‘clocking’ the mileage.


No clue how do I go 93×56 getting this info? I actually did do some googling and most people either take it to the dealership or reflash it with an EEPROM flasher.

Not to mention so many dtasheet in the jeep community have arduinos and would benefit from this. If I do go about pulling the code, is there a circuit that needs setup and any pre written code for this? Given that it’s ‘in-circuit’- I presume soldered – you’ll probably need to break the leads to CS, SK ,DI DO, so as to prevent the existing curcuitry from preventing your operations.

Hi, What do the professionals do when they need to change instrument cluster? Everything runs on smoke, let the smoke out, it stops running Well the good news is its a late model and I have everything I need from a junkyard for very cheap. Is there a connector next to this chip which does this?


Is this something the arduino can handle? I know this guy here did it with an off the shelf programmer, which is quite expensive compared to the arduino I all ready own.

TomGeorge Design and Repair of industrial control systems. I’ll look into that cloning. Just as the title states I wish to flash a 93c56 EEPROM in my jeep cherokee gauge cluster because my old gauge cluster has malfunctioned and the new one will have incorrect millage on the odometer.

But what is the format of the data? But not that easy.
