programming ATF750CL

You need an old fashioned programmer - one that puts +12V on certain pins.

From the datasheet abs. max. ratings:

Voltage on Any Pin with Respect to Ground -2.0V to +7.0V

Voltage on Input Pins with Respect to Ground During Programming -2.0V to

+14.0V

I haven't used a programmer like that for at least twenty years.

Try the 150x parts (not 1500) They have a JTAG port. Atmel also has a tool on their website wot generates SVF files. works in wine. you can upload with urjtag or similar. (use upstream urjtag. the one in debian is broken).

thanks for the hint, 150x parts are a bit "larger" as footprint and space isn't much in this application, but if I haven't other choices, I'll try them. Also one important thing that led me chose the ATF750 is separate clocks for all flip flops (I really use this feature in this design).

just re-compiled the design for the atf1502 which is *way* overkill. Now I guess I need a jtag usb adapter. Anything to suggest (even homebrew) that works on linux? Thanks

I've never actually tried to use avrdude for PLD programming. Can it even replay SVF files? or fusemaps or whatever?

PS: I don't know if you can use the ftdi based parts without headaches in linux(never tried) (but that's likely what you'll be using)

One thing to watch out are the header pinouts and supply voltage and switching levels.

At least they run fine on my Linuxes. I'm just using one on a TI/Stellaris evaluation card with a Raspberry Pi.
