Two different of those same chip were tested However Using another 93c56 from another manufacturer gives no similar error.

No, create an account now. When using the so8 adapter in the zif socket it works perfectly. Eeeprom the good news is its a late model and I have everything I need from a junkyard for very cheap. The errors are consistent and seem to happen with every bit value except FFFF.

Jan 11, 3. 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. Apr 30, 1, 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.

Parallel Port – Programming Serial EEPROM 93C56

You May Also Like: Is this something the arduino can handle? It won’t be easy, as they don’t want crooks ‘clocking’ the mileage.


I have checked the pins of the clip and they are all correct and if they weren’t it shouldn’t be able to write to the eeprom If this were a serial port I might try slowing down the bitrate, but eeeprom programmer seems to have no settings at all. This is what it should look like: Nov 5, 19 0. Use this tutorial to get your FPGA development environment setup and understand the tool set and 93c556 development process. And if so how would I go about doing this?

I just wonder if moving the chip might be a solution. I have also tried 8dip versions of this eeprom in this same programmer and they never give errors so I must assume it is eeptom clip. I would still like to know why it is able to write but not read? Your name esprom email address: Not to mention so many people in the jeep community have arduinos and would benefit from this.

Embedded Systems and Microcontrollers. Why is so8 test clip causing read errors with 93C56 eeprom TL programmer? But not that easy.

If I do go about pulling the code, is there a circuit that needs setup and any pre written code for this? TomGeorge Design and Repair of industrial control systems.

And here are a few other bit values, spliced together to save space In every case except FFFFthe even numbered bits 0,2,4, I am trying to read an Atmel 93C56B eeprom, so8 surface mount package, with this programmer. My best guess is a flaky connection on one of the wire eeptom pin connections at the back end of the clip. Is there a connector next to this chip which does this? But what is the format of the data? Yes, my password is: Jan 10, 2.


There must be a procedure 93c65 clone the new cluster from the old. I’ll see if I can find my old bitbasher – but given the datasheet you could figure it out. Jan 10, 1.

I just figured why not try with my arduino and learn a thing or two. However when I use the test clipit is giving me read errors on every other bit. I actually did do some googling and most people either take it to the dealership or reflash it with an EEPROM flasher.

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

Hi, What do the professionals do when they need to 93c65 instrument cluster? Posted by nimaid in forum: Do you already have an account?

Discussion in ‘ Embedded Systems and Microcontrollers ‘ started by cdsJan 10, Ill see what I can do about separating that chip. Quote of the day.
