PAL16L8 Problem

We have a BP Microsystems Model 1200 programmer that will not program Texas
Instruments TIBPAL16L8-25CN chips. We have two of the programmers and
neither works successfully.

They do program AMD/MMI PAL16L8ACN parts. We are running DOS V3.75A
software. Has anyone else had this problem? Did you find a work-around?

We called their customer support and left a voicemail but they have not
responded. We wonder if their tech support is in India nowadays?

Thanks to any and all that have input,
Ray

Ray,

It is too bad, but manufacturers use their own programming algorithms which
tend to be different for all parts even when they have the same type p.e.
16L8. Most likely the Texas part has another Jedec file content that cannot
be produced by Palasm. So you have two problems:
- You have to get the correct Jedec (by another development tool or a
conversion program.)
- Your programmer should be aware of the Texas pal you want to program.

As an aside, it could be worse. AMD ever changed the programming algorithm
of a part without changing the part number but that's a long time ago.

Unfortunately, I have a stock room full of the TI parts. I got a return call
from BP this morning so I'll see where that leads.

Interesting. That's why I included the .JED file thinking maybe someone
might see a problem although it looks pretty generic on the surface. I guess
I'll pound on BP Microsystems until I can get this resolved.

A B rev part is old enough that they published the algorithm. As did MMI.
They're close to the same, with only the programming voltages as the
variable. (TI did have the programming algorithms on their web site at
one point in time).

Check with TI to see if they changed the algorithm, and with BP to see
how it deals with the variation.

And double check the parts to see if some surplus dealer stuck you with
used junk.
