Is this something the arduino can handle? There must be a procedure to clone the new cluster from the old. TomGeorge Design and Repair of industrial control systems. I’ll see if I can find my old bitbasher – but given the datasheet you could figure it out.
93C56 – x8(2k) Serial CMOS EEPROM Technical Data
It won’t be easy, as they 93c566 want crooks ‘clocking’ the mileage. 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. Writing to the eeprom isn’t too hard if you have access to the pins. I just figured why not try with my arduino and learn a thing or two.

Given that it’s ‘in-circuit’- I presume soldered – you’ll probably need dataaheet break the leads to CS, SK ,DI DO, so as to prevent the existing curcuitry from preventing your operations. Not to mention so many people in the jeep community have arduinos and would benefit from this.
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.
Ill see what I can do about separating that chip. I’ll look into that cloning.
If I do go about pulling the code, datasheey there a circuit that needs setup and any pre written code for this? No clue how do I go about 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. It may be cheaper and less risky to go to a Cherokee dealer and get him datasehet do it And if so how would I go about doing this? Hi, What do the professionals do when they need to change instrument cluster?
Is there a connector next to this chip which does this? But not that easy. Just as the title states I wish datasehet 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.
I just wonder if moving the chip might be a solution. But what is the format of the data?
If you had the appropriate sw from the manufacturer I bet you could do this via the OBDII connector – datasueet I also bet they’re not telling you how!
