EPM7032S programming problem
- 5 years ago
As a replacement for the EPM7032S/7096S/7128S there is the current series ATF15xx from Atmel/Microchip.
They are drop in functionally compatible, and can use the same .POF file you generate for the Altera part via a translator program (POF2JED).
You need a new USB JTAG programmer from Atmel to program the parts with their JEDEC (text based) files.
But other than that overhead, I have successfully converted an number of legacy EPM7032S/7064S parts in PLCC44 from the existing Altera .POF files. YMMV of course.
So if you really need something like the EPM7nnnS series parts with 5.0V/3.3V compatibility I find the ATF15xx series very useful.
Mouser, DigiKey, etc stock these parts off the shelf.
Looks like I will have to go the Atmel route. Not as convenient in some ways for just a small amount of glue logic but may be able to stick some of the other functions in to use the space. I had come to the Altera/intel direction after finding I was unable to program ATF750s at a reasonable cost - 22V10 would not quite do the job. I think I must assume that my EPM7032s are fake or locked - not usable.
I will try the ATF1504 (I have some recovered devices) which may give me a 2 chip (+3V reg) solution. Discrete logic needed 5 or 6 but all 5V and through-hole, this solution will be all SM so more difficult to breadboard. (EPM7032 was also 2 chip solution but without Vreg)
Thanks for your interest

Sorry I was thinking about the EPM3032 route needing the 3.3V reg. I don't think the ATF1504 needs it but will check.
