content: Hi guysI am brand new with eeprom programming and all the other things that go along with it..I have two eeproms a 95128 and a 95020 I need to copy and edit, and was looking to get the MiniPro TL866 Universal Programmer to do the job.Is this the best programmer for the job, or is there something better?Is it a straight forward job to simply copy the data, edit, erase the eeprom then copy the edited data back, or is it more complicated?Any advice is very much appreciated...Thankslegepe

content: for those 2, an x-prog-m will do both of those for less than $100, (look for a clone)

content: Those are both SPI EEPROMs. You can program/read them with an Arduino and a handful of wires.When you're done, you have an Arduino leftover as well.

content: Hi guys and thanks for all your replies... but I feel no closer to finding the best programmer for this job...As I said I don't have any experience with this and need something that's as much "plug n play" as poss...I saw the YouTube vid on the - MiniPro TL866 Universal Programmer and it looked the business... the software looked easy enough for me to use too... (however, the vid is three years old) and its not that I don't want or can't learn new things in achieving my objective here with this... I just don't want to make costly mistakes...Anyway, thanks again...legepe

content: The best solution so far... for SPI EEPROMSAn Arduino, five wires and 20 lines of code.Another 50 lines to implement a simple hex viewer/editor

content: Those 2 eproms are supported by the minipro tl866.It should be pretty easy to do with it.You can download the tl866 software to see it yourself from Autoelectric's site and see how the software works. It is simple.http://www.autoelectric.cn/MiniPro/minipro_setup.rar

content: The TL866 supports those devices and will do the job easily. You can edit data within the TL866 software. Just read the device, save a copy of the data, then edit as needed, and write back to the device. The editor is nothing special but it works. I like that it will highlight all changed bytes in red so that you know what you have changed.The TL866 is very inexpensive and has a big supported device list. Yes, some 'professional' programmers will have broader device support, but will also cost at least 10x as much. If you buy a TL866, get one with many adapters for various PLCC and SOIC chips. Make sure you get at least an 8-pin SOIC socket, I find that I use that one quite often for EEPROMs.

content: Thanks very much for the further replies on this guys...I've had a look at the Arduino tutorial and it looks very interesting... my problem especially at the moment is time (I already need more than 24hrs in a day) and this would take me some time to get into and learn more about. Mainly because of this I will have to opt of the tl866 as it seems it will do what I need.The only other question is should I buy the tl866A or the CS?I will look into the Arduino at a later date once I have more time available...Thanks again... really appreciated...legepe

content: The A version includes ICSP which can be useful but if you don't need it you can hack the CS version to have it later.The CS can be converted to A via software hack using Radioman's open source TL866 software. (Radioman is a member here on EEVBlog)https://github.com/radiomanV/TL866It can be upgraded by just changing the firmware in that utility (about 5 mins) and soldering a header to the pcb.. If time is your enemy just go for the A version. It is only a few $ more.

content: Thanks a lot... I got the cs version already.. I'll maybe have a go at changing the firmware if i find that I need it...
