I have a 5V 32M mask rom in a SOP-44 footprint on a Yamaha MU100 that has gone bad (this is the same synth used on KeyboardMania).
Here is the datasheet for the ROM that's gone bad: https://datasheetspdf.com/pdf-file/613121/SamsungSemiconductor/KM23C32000AG/1
I can't seem to find any 5V 32M EPROMs that are in a SOP-44 footprint; the 5V compatible ROMs made for that footprint seem to be only mask roms.
There ARE plenty of 5V 32M EPROMs, but they only come in DIP-42.
The EPROM that fits this best is the good ol' M27C322, but this only comes in DIP (and SDIP, but the pitch is still too large): https://pdf1.alldatasheet.com/datasheet-pdf/view/22821/STMICROELECTRONICS/M27C322.html
So my questions are:
1) is there a 5V 32M EPROM in SOP-44 somewhere that I'm missing?
2) If not, Is there an DIP-42 -to- SOP-44 adapter somewhere?
edit: BTW, I checked and the mask ROM is being used word mode, so the M27C322 would be appropriate here if I can get it into the footprint.
