'[PIC]: programming sockets...'
2003\02\28@123850 by William Chops Westfield

face picon face
Does anyone know where I can get an adaptor for programming 28pin SOIC
parts in a nominally "dip" programmer?  For less than $50?  Or just a
usable 28so socket?

Thanks

Yup, I do for one.

Is ICSP not an option ?

I don't think so.  The chips of immediate interest are PIC16C57's.
To what extent CAN you do ICSP (via SMT test clip) of old parts, if
most of the relevant signals are normally outputs (ie connected only
to inputs of other chips/etc)  I don't mind going slowly to allow for
the long leads, I think...

I was aware of Emulation technology (~$77) and a couple other adaptors
from programmer vendors in that same $70-$100+ price range.  I was hoping
for something cheaper...

If you use beefy divers (like a HCT244 octal buffer f.ex. of which some
versions can drive 200mA per output into the bus) you can dyi. I have
never progged SMT 16C54s (and 57s), only DIL, out of circuit. If you can
arrange for contact pads in the circuit and make a bed-of-nails fixture
you should be set to do it icsp style imho.

The bed of nails will cost you far more than $50 to get right, in hours
invested imho. If you use only 1-2 devices I don't know if it makes sense
to use those chips. If you make 100 look again at the 70 cents/part a $70
socket will cost you.

www.aprilog.com has a huge selection of adapters, sockets, etc. I
got a 8 pin SOIC for $9.

How about
test-socket.com/perl/part.pl/sel::/SOIC-test-sockets,652D028221X.
htm for example.

BTW, I found this site few weeks ago based on a recommendation on this
list. Thanks.
