'[a bit OT] GAL programmer schematic ?'

Pavel Korensky
Hello,
I know that this question is a bit off-topic, but I spent several hours
seeking the internet without any success.
Please, can anybody tell me, where I can find some GAL (22V10 specifically)
programmer schematics and software ?
I tried to find some (or at least find the programming specs. for 22V10)
and I was not succesfull.
I only found ads for large expensive
EPROM/EEPROM/PIC/GAL/FPGA/WholeUniverse programmers which costs megabucks
and are overkill for me.
Thanx a lot

The reason you are having trouble finding anything is because the GAL
manufacturers decided a long time ago not to release any information
on programming to anyone other than the universal programmer boys.
Personally I think this was a STUPID decision, but you do have some
alternatives. There are a few designs for GAL programmers in older
issues of Electronics Now and some of the UK magazines, but the
problem is that I have never seen one for the 22V10, only the 16V8 and
20V8 devices. The other problem with these designs is that they
invariably use a GAL in their design, which causes the proverbial
chicken and-and-egg syndrome. Since these projects were published
quite a few years ago, it is unlikely you can still buy the
pre-programmed GAL's to build one. You should be able to get the
source from the E/N web site though, and you might be able to find
some kind soul locally to program it for you. If you can use something
other than a 22V10, then the GAL manufacturers are more liberal with
programming specs for their ISP devices, since the whole purpose
behind these things is to be programmed in the field.
I know it can is a bit expensive for a hobbyist, but I would recommend
you bite the bullet and invest in a Needhams EMP-20 programmer, which
handles several brands of 22V10 (the EMP-10 only works with Lattice
22V10's). For about $450 US you will get a programmer than you will
probably never outgrow, and if you buy it from Digi-Key, they will
throw in the PIC module for free (of course I discovered this AFTER I
had bought mine somewhere else), which is a $25 US value.

The Lattice 22V10 is very easy to program via a simple parallel port
interface. You can get a free CD-ROM with development software, data,
etc. from Lattice distributors. It's really intended for their larger
CPLDs, but the 22V10 is included.

Not quite schematics, but there ARE some inexpensive programmers
at JDR Microdevices (http://www.jdr.com).

Elektor magazine did one that did 16V8 and 20V8,
and then did a kludge board for a 22V10.
Which needed you to buy more software from them.
Only did a few brands of these chips, which are
now all but replaced by 22V10 chips. Manufacturers
are not so motivated to make the smaller chips.
Most hobbyists will only want a few chips, so
a few pence more per chip is no problem, nor
getting particular manufacturers chips.
I'd suggest you use Lattice Logic's 22V10 chips.
Lattice specialise in in-site serial programming so
they have to be open about the programming specs.
I'd expect these to be popular amongst hobbyists,
as it should be as easy to make a programmer for
them as hobbyist PIC programmers.

re: Lattice ispGAL22V10
To followup on Leon's comments, I've added a schematic for a buffered
parallel port cable and programming board that allows you to program Lattice
Semiconductor's ispLSI1016, ispLSI2032, and ispGAL22V10 devices. This is for
folks that don't have Lattice's ISP Starter Kit. You can download the
archive from my web page at:
http://www.teleport.com/~thandley/Wilbure.htm
To program their ispGAL22V10 all you need is the buffered cable which
basically contains a 74HC367 and some passive components, and the ISP Daisy
Chain Download software which is also on Lattice's web site.
For more information about Lattice Semiconductor's products and to
download the ISP Daisy Chain Download software and/or ISP Synario design
software, contact:
