I’ll see if I can find my old bitbasher – but given the datasheet you could figure it out. Well the good news is its 93c556 late model and I have everything I need from a junkyard for very cheap.

Writing to the eeprom isn’t too hard if you have access to the pins.

Btw the chip is not soldered to anything, it is attached only to the test clip Chinese manufacturer of the programmer: Everything runs on smoke, let the smoke out, it stops running I just wonder if moving the chip might be a solution. Apr 30, 1, 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.

Jan 11, 3. Digital Signal Processing is the mathematical manipulation of an information signal, such as audio, temperature, voice, and video and modify or improve them in some manner. But what is the format of the data? However when I use the test clipit is giving me read errors on every other bit.


My best guess is a flaky connection on one of the wire to pin connections at the back end of the clip. I’ll look into that cloning.

You May Also Like: I would still like to know why it is able to write but not read? And if so how would I go about doing this? I just figured why not try with my arduino and learn a thing or two.

Yes, my password is: Please do not take anything for granted, the answer maybe dead simple but I’m just not seeing it. Do you already have an account? This is what it should look like: I am trying 9c356 read an Atmel 93C56B eeprom, so8 surface mount package, with this programmer.

This is why we test Posted by nsaspook in forum: No, create an account now. Is there a connector next to this chip which does this? If I do go about pulling the code, is there a circuit that needs setup and any pre written code for this?

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! Not to mention so many people in the jeep community have arduinos and would benefit from this.

Parallel Port – Programming Serial EEPROM 93C56

I have also tried 8dip versions of this eeprom in this same programmer and eerom never give errors so I must assume it is the clip. Discussion in ‘ Embedded Systems and Microcontrollers ‘ started by cdsJan 10, But not that easy.


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.

When using the so8 adapter in the zif socket it works perfectly. Hi, What do the professionals do when they need to change instrument cluster? It may be cheaper and less risky to go to a Cherokee dealer and get him to do it It won’t be easy, as they don’t want crooks ‘clocking’ the mileage.

Why is so8 test clip causing read errors with 93C56 eeprom (TL866 programmer)?

The errors are consistent and seem to happen with every bit value except FFFF. Why is so8 test clip causing read errors with 93C56 eeprom TL programmer? The reviews for this clip dont mention this problem, and it is sold by the same company that sells the programmer.

Your name or email address: I actually did do some googling and most people either take it to the dealership or reflash it with an EEPROM flasher. Ill see what I can do about separating that chip.
