EPM7032S programming problem

Quartus II 64bit Version 13.0.1 Build 232 06/12/2013 SJ Web edition (SP1 installed) programming EPM7032SLC44-10 with USB-Blaster (JTAG connections from IDC header to IC seem intact) (Pull-up 10k o...

    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.

I use that exact same QuartusII web version to program EPM7064SLC44-10 devices.

I use a TerAsic Blaster which is a clone of the Altera USB Blaster.

I can blank check, program, verify, security fuse enable/disable with 100% success.

Erase and examine are not implemented in this Quartus version for this series of parts.

My understanding is MaxPlus2 version 9.0 was the last release that supported Examine/Erase for the EPM7K series.

Verify works (read device) but Examine is not implemented. Explain that one to me, Altera/Intel. But I digress.

My EPM7064 devices have white silkscreen topside marking and they were purchased thru an authorized Altera distributor as new (long ago).

So you don't mention how you acquired your devices that won't program. Authorized distributor? Ebay? Random web seller in China?

Here is a screen shot of my programming screen ...

    Many thanks for the reply.

    My devices with the white printing were purchase a while ago - not from Ebay but I've long since lost the paperwork.

    These were the ones which were at least recognised.

    The rest which were bought recently from 'lucas89-8' on Ebay are the ones which do not work at all!

    These have the marking etched into the top so may well be fake (why bother?).

    Most retailers now seem to list these (genuine) devices as obsolete and unavailable.

    This is a shame for projects which need a small amount of interfacing at 5V - already had a problem with some Atmel devices requiring a £1k programmer.

    It would be nice if 3.3V devices were at least 5V tolerant without extra components - EPM3032 probably OK but needs 3.3V supply .

    Looks like I'll have to go that way.

    Thanks
