Programming 24 pin tsop32 #11

Hello, Do you have a gerber of the programming adapter for the 24 pin pcb?

Thanks for reading, Stefano

OlegMishin commented 1 month ago

Hi Stefano, I don't have any adapter for 24pin FlashROM so far. For flashing I did use a prototype board with 32 pin male header for TL866 connection and 24 pin socket + 10 pin header for higher address lines and OE#/WE# signals.

Thank you Oleg. I'm preparing an adapter right now. Just to know, i followed your schematics, the only doubt is which signals are required to program an SST39sf040 i.e. I would exclude 5v headers on the 24 pin pcb.. The 5v and gnd are taken from the TL866 pins . Am i doing right?

No problem. You are right. You need to follow pinout of SST39SF040 to make all connections available between the Flash IC and TL866's socket. Actually, the connections already in the schematics:

Hi Oleg. I built a programmer adapter and it worked. Thanks for your hints. Can i ask you if i can use SST39VF010 (not 5V) for this prj despite of SST39SF010/40 ?

OlegMishin commented 3 weeks ago

Hi, It depends on your target application as the FlashROM adapter is just wires betwiin DIP pins and its Flash memory. I've never seen 3.3V DIP24 ROM. Luckily SF are still available at Digikey/Mouser/etc.

Hi, trying to program Intel E28F010 the TL866 programmer gives FF FF as ID. SST39SF040s instead work like a charm. Any advice when programming intel above? Thanks, Stefano

OlegMishin commented 2 weeks ago

Hi Stefano, In my memory, E28F010 has longer package and it doesn't fit to the 24-pin FlashROM board. Or did you find short one(as SST39SF0xx)? I used the Intel Flash E28F010 in my other adapter board without any issues. Maybe the Flash is dead or soldering problem. I would suggest to check the Flash at first with original TSOP adapter as below to be sure it is working.
