PAL or GAL programmer
Shane Tow
Does anyone have any information on some software and schematics for a PAL
or GAL programmer? I would like to be able to program the 22V10 and 20V8.
Or does anyone know of a relatively inexpensive programmer that programs
PALs or GALs and maybe EEPROM?
Thanks for your help,

I don't have any schematics for one ,but if you decide to go the route of
buying one, Digikey has one for about 220 bucks that will do EPROM, EEPROM,
GAL, Microcontrollers, and flash.
PAL I'm not sure about.
It's probably on their website

I believe that would be the EMP-10 from Needham's. It will program *one
or two* kinds of GAL -- 22V10 and 22V10B, not sure which manufacturers.
You generally can't get the algorithms without convincing the manuf.
that you have a legitimate need (or that you're a student), and if you
succeed at that, you'll probably need to sign a non-disclosure agreement.
That's why you can't easily find plans for programmers.
I posted a message asking for info on the EMP-20 and EMUPA programmers
a few days ago. So far, all I've gotten is two messages from people who
want me to pass along whatever I hear. In another thread, someone is
claiming that extensions and updates for the EMP-20's software are being
curtailed. It's looking pretty grim for the hobbyist -- at least the
kind of hobbyist who can't spend several thousand dollars on the tools
of his hobby.
(Actually, that's an overstatement, as Steve Walz and others will point
out. Still, this programmer situation is really starting to get on
my nerves...)

i bought a xeltek from general devices instruments in san jose,
www.generaldevices.com , email icde...@best.com
sales 408-241-7376
what's nice is i can d/l the most recent libraries needed, problem is
i've never had to d/l upgrades since 1990?
digi-key sells the emp-20 and 30, plugs into parallel port.

There is a GAL programmer on this site:

I haven't tried it yet. I was thinking about building it on a JDR wire wrap board.

Try:
a) ftp.unina.it/pub/Other/electronics/ftp.armory.com/GAL/rgbpld.zip
b) ftp://sistudio.com/pub/mchip/ files galprog.zip and galptiff.zip
You can find simple GAL programmers there (using PIC uC).
Hope it helps.

Thanks for the pointer!
Actually, that URL is dead; try http://www.m2l.com/
Unfortunately, this doesn't look like a good bet, either. In the
base configuration, it only does EPROM/EEPROM/flash. It's $60 for
a PEEL adapter, $50 for 8748/49, $40 for 8751, $40 for 8755, $40-50
each for the 18/28, 28/40, and 8-pin PIC series... in other words,
it's not much cheaper than the EMP-20 in the long run.
I'll have a look at the Xeltek...

The May 1994 (?) issue of Electronics Now magazine had an article on GAL
programming for the Lattice parts. Look at Steve Walz's website at:
ftp://ftp.armory.com/pub/user/rstevew/GAL/
and check out the rgbpld.* files.
Hope this helps.....

I have had bad experiences with XelTek. Essentially this comes from their
devices not being certified by the semiconductor manufacturers.
I've receive batches of 20V8's that could not be programmed by the SuperPro,
but worked fine with other programmers. Also I've had two units
completely die in service.
I recommend the Tribal TUP-series programmers. Slightly more expensive,
but seem to be more reliable, have full certifications, and they are
good about upgrading old hardware for new devices -- just download the
updates.

Me too. I have had two Superpro II's. My first one was also one of theirs first,
so we all had to get used to it- me to use it and Xeltek to assemble it properly
;-)At that time I have had so many problems with it that our local service for
Xeltek finally gave up and copied me the schematics for it so I could repair it
myself. Oh yes, forgot to mention it, ther was one marginal bug in the
schematics also, they have mixed up +5V and +12V in it so I almost roasted it
when when trying to fix it...
And software was very bad also. Still, if I were to by programmer today in $200
class, I would probably buy (even used one)Superpro II again. Why? Well, after
producing II's for some time their workers eventually got a grip to it and now
Superpros even work, and software made its marathon from v1.0 (practicaly
unusable) to 2.6c (very good) in 0.01 increments...
In my opinion it's very good value for the money, If you are hobbist or not very
demanding profesional. Otherwise take a look at Data I/O or one of those firms
that you can find in every EPROM databook under: "supported programmers", but be
prepared to sell your car and maybe a close relative...
Some time ago I have sold both IIs, coughed up the difference and bought myself
III.
I must say that we both got several years older, but not any brighter (Xeltek
and me).
First one died on me while testing it, but it was only bad solder joint in PSU,
so in half an hour thing was working again, but software... It was version 1.0A
!!!!! (No! Not again!)
They seem to have guessed my thoughts and jumped from that to 2.1 in a single
jump.
Although I think this was more idea of the marketing department than true
picture of advance, it worked better. Current version is 2.4a and this works
even from Windozes.
Earlier version seemed to work under Wins, but it reported bad chip in the
middle of programming in some cases.
Oh yes, one more thing if you are going to use Superpro II or any other
programmer that draws power from PC, check your PSU! Supepro II is not
particularly heavy current consumer but if you have PSU that is "on the edge"
even without programmer, you are about to see pretty od behaviour of your PC and
you will not know what to blame....

So you want to build a PLD programmer: a FAQ File
[Last Revised: January 29, 1996]
(The following is aimed at the level of the basement hacker,
restricted to lower complexity parts. Which is what I've found
in the surplus market.)
So you want to build a logic device programmer.
Here's a list of articles and databooks that I've scraped together.
Grouped by devices supported and in order of usefulness (IMHO).
Just remember that if you build your own programmer, factor in
some money for test data (that is, destroyed parts). Unless you're
using cheap parts, the $500 to $700 you tried to avoid spending for
an inexpensive programmer could add up sooner than you expected.
First, be aware that the manufacturers don't feel it's in their
interest to give you enough information to build one. There's a
couple of reasons. Some them make money by selling programmers
and software. Some of them don't want to spend a lot of money
trying to figure out why you (and thousands others like you) can't
get parts to program (or worse, stay programmed) using your homemade
programmer.
So, starting around 1985, most manufacturers have removed this
information from their databooks. Expect most CMOS parts to
have proprietary algorithms. Also expect as parts are redesigned
to be faster, the old programming algorithms may be obselete, or
have certain parameters in them shift.
But if you are convincing, some of the manufacturers will give
you the information on a nondisclosure basis. (I've heard
National and TI are pretty nice. And Cypress doesn't even require a
nondisclosure agreement. But Lattice and AMD are downright rude.
Unfortunatly, National is reported to be getting out of this business.)
And there is a new trend in industry that will help the hobbyist.
Manufacturers would like to control their inventory, but the
way older parts are programmed adds extra (possibly) expensive
steps to the process of making a circuit board: procuring and
inventorying the unprogrammed parts, programming them, reinventorying
the programmed parts (and insuring they are programmed and marked
correctly), making sure they are available to be inserted in the
circuit board, and placed the right location ...
And after all of that, the board is tested in Automatic Test Equipment.
This automatic test equipment has the same sort of electronics that
a device programmer has (and have been used for this at many companies).
So why not design parts that can easily (without destroying connected
circuitry) programmed during the final test stage and skip many of
the steps mentioned in the previous paragraph.
In order to do this, the semiconductor companies have to make the
parts easy to program, and release the programming algorithms.
Intel and Lattice with their Flex and ispLSI families are doing this.
Altera has taken over Intel's PLD operation as of October '94.
1. GALs (EEPROM based), from Lattice, National and SGS-Thomson
"Build This PLD Programmer" by Robert G. Brown
Electronics Now (magazine), May 1994
This is a simple programmer limited to the 16v8 and 20v8
parts. It consists of two circuit cards, one a general
purpose parallel port for the IBM PC and a programmer
card with the drivers, ZIF socket, and voltage regulators.
(Very similar to the Elektor project.)
Various kits and software available from
R.G. Brown

"Project: GAL programmer" by Manfred Nosswitz.
Elektor Electronics (magazine), May 1992
This is a simple (5 IC's, 7 transistors, 2 voltage reg.) board
driven by a program (in this case for an IBM PC or clone) using
the computer's printer port. It supports the 16v8, 20v8 original
and A versions.
"Project: GAL Programmer Upgrade" by M. Nosswitz
Elektor Electronics, June 1993
An add-on board with a D/A converter to allow a variable programming
voltage, and a new software driver. Now programs B version GALS,
22V10's, 20RA10's, and the GAL6001 PLA.
The software and PC boards are available through the Elektor
publishers/franchises in various countries.
In the US this is Old Colony Sound Lab (the publishers of
Audio Amateur, and the former publisher of the US edition of
Elektor Electronics).

"Generic Array Logic (GAL)" D. Gembris
Elektor Electronics, April 1992
A description of the architechture of a GAL, along with the
programming algorithms. Unfortunatly this describes the
nonvolatile memory layout for the original version parts, and
the A version parts would not work if this information were used.
Some other information is left out, including describing the
nonvolatile memory register that contains the part ID code and
manufacturer. (This article is useful if you want to disassemble
the software from the previous reference, but incomplete otherwise.
Not really needed if you want to build and use the project as is.)
2. Cypress and Samsung (UVEPROM based)
Contrary to the trend. Cypress Semiconductor published the
algorithms for the simpler PLD chips they produced. They
have since discontinued this, and you have to request them,
but no special agreement is required. As of the 1990 databook,
they included the algorithms for their 16L8, 16R8, 16R6,
16R4, 20G10 (like a smaller 22v10), and their 22v10 devices.
Judging from the algorithms in their 1988 databook, Samsung
is a second source for Cypress. Their CPL 20 family is the
same as the Cypress devices. In addition, they have 24 pin
devices with the same technology that implement the 20L10,
20L8, 20R8, 20R6, and 20R4 devices.
"EPLD programmer design" John Cromie
Electronics & Wireless World, February 1989
An article describing a single chip microprocessor driven
programmer (using a Hitachi 63701) that programs the devices.
"Contact the author for software.", a common trend in
this publication's "projects".
3. PEEL18CV8 (EEPROM), from International CMOS Technology, Gould AMI
"Create Your Own IC's", Bill Green
Popular Electronics, January 1990
A single board Z80 based programmer for the PEEL18CV8 using
keyboard entry. No algorithm description. PLD and EPROM
for z80 program needed to duplicate. (Listed price was
cheap, about $80 in 1990.) Later versions were produced that
had an interface to download from a computer, rather than
keypad only entry.
4. CPLDs from Intel/Altera and Lattice
Databooks from Lattice, "pLSI and ispLSI Data Book and Handbook"
and Intel, "Programmable Logic" have the interface and download
specifications. (The catch here is that the data to be downloaded
needs to be generated from a manufacturer provided software as
the internal layout and mapping of the device are still proprietary.)
This software is cheap or free, but you need to contact the
company, or find their ftp site on the internet.
As part of the Lattice's GAL line of parts, there is an ispGAL22v10
part in 28 pin PLCC package. In the 1994 Lattice databook, there are
sufficient information to download the part using the onboard serial
interface. And, since it is a standard architecture supported by
most logic compiler/assemblers, there isn't a problem with a proprietary
interal layout.
A free demo logic compiler/programmer package is available for some of
the Altera EPX7xx parts from Xess Corp. (info at http://www.xess.com/)
or files in the ftp://ftp.vnet.net/pub/users/xess/PLDshell/ directory.
See the December 1995 Circuit Cellar Ink magazine for more details.
5. Classic Bipolar Fuse Programmed PALS from MMI, National, TI
"A PAL Programmer" and "Getting Started with PALS" , Robert A. Freedman
Byte, January 1987
A programmer for the original PAL family (too many to list). Implemented
in the form of a IBM PC expansion card. (And sold for a while by
Microway). Design is implemented with PALs.
PAL Programmable Array Logic Handbook
Monolithic Memories, 1981

McGraw-Hill, 1981
A hardback copy of the MMI databook, including the programming

National Semiconductor, 1983
Databook back when they still published the algorithms.

Texas Instruments, 1985
Databook back when they still published the algorithms.

TI actually published some of the algorithms in the advertising
pages in the Custom/Semicustom section.
6. AMD version of the classic PALS (Fuse Programmed)
Programmable Array Logic Handbook
Advanced Micro Devices, 1986-1987
This has the algorithms for the bipolar amPAL devices that
existed at the time, including the amPAL22V10. These
differ from the 1983 algorithms, which were preliminary.
7. PLS153, PLS159 from Signetics (Fuse Programmed)
