20 pin ribbon style cable

[Bryan Martin]

Anyone have any info on where to possible find a part.

I am programming/testing a lot of atmel at90s2313 20 pin DIP sockets. My
intentions are to take a 20pin dip socket and connect a cable to it so I can
move the microcontroller from test bench to programming and back with ease
and without having to remove the chip from the socket. In otherwords say I
wanted to move the chip off the devboard to reprogram I simply want to
unhook the cable which is attached to the DIP socket and hook it into the
cable from the programmer. Oh and yes I already know they have ISP
programmers ETC and thats not what I am looking for.

I am having problems finding a cable with the right size end that would
allow me to do this by connecting directly to the DIP socket. If anyone has
any ideas please post.

Hi, Bryan. I'm sure you could do as better job of describing the cable
you need.

Are you looking for a ribbon cable which has a 20-pin DIP plug on each
side? In the Digi-Key catalog, you could get one of their
A6MMT-2006G-ND for $4.06 ea. This is 6" long, which should be enough
for what you want. You should keep the ribbon cable as short as
possible. But if you want an 18" one, the P/N is A6MMT-2018-ND.

If you want to have a pair of sockets at the other end of the ribbon
cable (one for the DIP plug, and one for inserting microcontrollers to
program), buy the above, and then make the dual socket setup on a piece
of perfboard.

Between the two of these, I was able to do a few things with a
development board.

Ask for a catalog when you place your order -- they're free, and are a
big help when you're trying to figure out the names of the doohickeys
we use.

If neither of these will do, could you describe what you need with more
precision?

1) The 20-pin Atmel IC is called a DIP (Dual In-line Package).

2) The (usually) black thing you plug the 20-pin Atmel DIP part into
is called a DIP Socket.

3) The connector at the end of the ribbon cable that plugs into a DIP
socket is called a Ribbon Cable DIP Plug.

4) The Atmel chip itself is called the microcontroller.

5) The small board you're using to program the Atmel is usually called
the development board.

6) The board the microcontroller is eventually going to be used in is
sometimes called the target board.

Feel free to post again.

Good luck
Chris

I think you got something similar to what I am looking for. Sad part is
that I do actually have a digikey catalog and have searched the site but
could not locate it among all the other things.

Thanks again

20-conductor ribbon cable is pretty common stuff, so I'm assuming you
aren't really looking for "cable", what you want is the part that goes
on the end.

Maybe your search is for a 20-pin DIP plug that goes onto ribbon cable?
AMP makes them, part #746613-5. There are also solder-type headers that
plug into DIP sockets. All this stuff was the rave 30 years ago .

All that said, you really really want to go to in-circuit programming.
Why any developer would go through all this crap with plugging and
unplugging chips all the time is beyond me, especially in our modern
surface-mount world.

Tim.

solder .05" ribbon to a 20 pin DIP wire-wrap soccket.

ISTM that' it'd be easier to superglue a perspex handle to the
back of the chip.
