    Re: Using my CH341A.

    I successfully read and wrote in circuit the 93c56 and 93A56 EEPROM's. I didn't have to power on the circuit, I just used the SOIC8 test clip with the interface
    that I built!
    I could not use the CH341a though, so I have no use for that interface... at least for now.

    Re: Using my CH341A.

    Well, I did it! I built myself a Pony Prog adapter for the programming of 93cxx EEProms using PonyProg and the result is: SUCCESS! I managed to write a 93c46 EEPROM that I bought from a local shop for testing purposes.
    Next: I will try to read/write the 93c56 in circuit. Keep ur fingers crossed for me, pls !

    I uploaded your archive to virusTotal to verify it and some AV engines have detected trojans. ( CAT-QuickHeal : Trojan.IGENERIC /// MaxSecure: Trojan.Malware.74274250.susgen // SecureAge APEX: Malicious//
    SentinelOne (Static ML): DFI - Suspicious PE//Trapmine: Malicious.high.ml.score)

    Are they just false positives, or what?...

    Re: Using my CH341A.

    I see... If 12 V is the voltage from those serial pins, then I think I definitely need a 5v regulator... But if I don't have the 5 V regulator (LM2936z-5), what else can I do using other common electronic parts that are easily available? Or can I just eliminate the 1N4148 (D1, D2 and D3) along with the regulator and the other capacitors (C3, C4 and C12) and just use a 5V from USB or from an 5V PSU rail to drive the pin 1 (that's VCC, + PE + ORG of the 93cxx EEPROM ) ?

    Re: Using my CH341A.

    I inverted in the image below the colors of the components which I want to remove from the Base Board interface, and I retraced with red color the connections that I think it needs to be done in the circuit. Would it work this way?...

    Re: Using my CH341A.

    I've started looking yesterday on the Pony prog 2000 website. As far as I see, I need to build the Base board (SI Prog) + the 93cxx adapter (Microwire eeprom adapter) using the schematics provided on that website. Is that right?
    I want to build those, but as simple as it can be... So what would be the simplest schematic that I should build? Do I really need the extra power source? And if I do, can I use the 5V rail from the PC's PSU for this purpose instead of the one presented on the Base board schematics ?

    Re: Using my CH341A.



    thank you R_J. I followed the link you gave me, but the info found there it doesn't help me... As far as I know the 93C56 EEPROM of my car has a bit organization of 128x16 bits, not 256x8 bits. The project from the link you sent me has a limitation in this respect (only 8-bit data organization (ORG pin Low) supported)....

    Re: Using my CH341A.



    The CH341a software that I've got, doesn't list 93Cxx EEPROM series... So I'm still wondering how can I connect the 93c56 EEPROM chip so I can program it.



    When I'm testing the CH341a software (v1.29, v1.3 etc) that I found on the internet, using the Virus Total website, it shows me that it is infected with malware (one of them it is flagged by 17 antivirus engines!). Are they just false positives, or not? Where can I find a clean and newer version of this software?...

    Re: Using my CH341A.

    Ok, thank you for your inputs.
    Supposedly that I have a new 93c56B EEPROM, how do I have to connect it to the CH341a in order to program it? From the 93c56 datasheet I can see no match between the pin configuration of 93c56 EEPROM and the ZIF lock of the CH341a PCB.

    Re: Using my CH341A.

    Thank you for the quick response, Stj!

    That means that I will have to choose from the drop down list the 93c56 EEPROM that I want to read/programm? what if I don't find it listed? Can I select another with similar memory size?


    I read on internet that it can be done on board, all I need is to short the crystal oscillator without any other modifications (the 93c56 is on a car ECM). If it can be done, why did they make a SOIC Clip? On the internet its advertised that with this clip one can programm the EEPROM without any ...

    Re: Using my CH341A.

    Hello!
    I bought myself a CH341 Mini programmer (black mobo) and a SOIC 8 clip to use it for hot programming an 93c56 EEPROM , and I'm stuck because I don't know how to connect the 93cxx EEPROM to the programmer. At first, I used an old video card to test the CH431A how it's working so I connected the SOIC Clip's interface to the slot for 25XX with the no 1 pin to the left upper corner of the CH341a's ZIF lock, I attached the miniclip to the 8 pins of the videocard's EEPROM (with the red wire of the clip to the EEPROM pin no 1 - marked on the videocard...
