TI and the MiniPro TL866 EPROM Programmer

Recommended Posts

I don't know of anywhere such a list exists. There might be a manufacturer list but the individual chips' ID numbers are almost constantly updated and changed as the chips are introduced and marketed.

Anyone know where I can get a list of Device IDs? For example, Device ID = 97 85. Who makes it and what is it? TI 27C512 15JL.

 

Or is this information generally mfg specific and too arbitrary to include in a comprehensive list?

 

The Device ID data is manufacturer-specific and chip specific too. The main problem with using it is that there are so many fake chips out there now with no Device IDs at all, that the whole Device ID system is starting to work more like a "genuine chip detector" than as the failsafe identifier it was intended to be when programming a chip.

 

The other problem is that there is no comprehensive list of Device IDs that I've ever come across. There must be one out there somewhere though, as comprehensive lists are built into the software for every single EPROM burner known to man. I suspect that the easiest course of action for a manufacturer adding a new chip to their software is to get one, read out the Device ID, find the correct programming algorithm from the data sheet, and add everything to their EPROM programming list. Eventually, they'll have a pretty comprehensive data set in there.

So, I still have the original 866 that Bob sent me the link to on eBay (the legit one).  Still running v6.85, no issues.

 

What makes the II special that I would want to upgrade to it?  Also, there are 200+ sellers on ebay selling it right now, so which one are the legit ones?

All of them are probably legit. The T56 was available on Ebay from the manufacturer for $156. Keep in mind that the TL866II will NOT do anything above 18V.

So, back to my question - what won't my 866CS do that the new ones (TL866II and T66) will? :)  

 

I've been able to handle just about everything so far that I need - 1284P, 27XX, 27XXX, 29FXXX, 49FXXX, 27C010/020/040, etc.

 

The only thing I have ever had difficulty using the 866CS or my 844USB (BK Precision/Elnec) programmers for has been PALs/GALs.  Those are the really strange beasts that I have trouble reading/programming.

The TL866CS has a somewhat limited palette of 3V chips and PALs/GALs but there are adapters for most lower voltage chips for a couple of $ on Ebay. The 1.8V adapters for the TL866 will do W25 and MX25 series chips.

I think this may be a trade secret between the IC vendors and the programmer vendors.  I was trying to find a device ID for a AMD AM27C256 the other date, and came up with zilch.  Its not in the official AMD AM27C56 data sheet, which should be the source of all technical data. The reason I needed this is I have three different AM27C256 which all produce diffident device IDs on my MiniPro TL866II plus.  Unless I uncheck the "device ID check" box, the EPROMs won't program.  Anyone else seen this?

They are likely "midnight runs" of the chips from China. Counterfeit chips are the norm in chips produced there. I always uncheck the ID box if the chip is one from other than a verified US source. The US chips may cost more individually, but they are better in the long run. You can get up to 50% of defective chips in an order from China that will not program at all.

Agree 100% on sourcing ICs from China.  Hit or miss at best.  Sometimes its worth taking the chance and sometimes they're the only source. 

 

These parts were from a reputable US distributor, so I would have expected them to be the real deal.  Of course no one has made 27C256 new for almost 30 years from what I can tell.  All mine have date codes from the '80s.

Unicorn Electronics (Hodge16 on Ebay) is my chosen source. Everything that I have ever ordered from them programs first time, every time.
