Does anybody know of a protoboard for the 16F913 / 916 family? I know
its a relatively new part but I'm coming up completely dry looking for one.

Thanks,

Alden Hart

Not exactly what you want but similar.
Microchip has the simple 44-pin demo board with 16F917. It is also bundled
with PICKit 2 Debug Express.

the dil version looks like a pretty standard 40 pin pic pinout so any
generic 40 pin pic demo board should be usable.

Xiaofan,

The 917 QFN may be a good place to start. Ultimately I'll probably have
to fashion some kind of 28 pin SDIP board. I guess I'm just still more
comfortable with through hole for prototyping.

Thanks for the reply.

These parts have the same 28 pin footprint as many other PICs, like the
16F876, 18F252, etc.  My QuickProto-01 prototyping board supports this
footprint.  http://www.embedinc.com/products/qprot01/index.htm

Huh?  The data sheet, line card, and everything else I've looked at shows
these as 28 pin devices.

sorry my mistake its the 914 and 917 that are 40 pin (though you only said
you were looking for a demo board for the family not a particular device).

the 28 dils also look like a pretty standard pinout to me though.

Tthe 40-pins chips are the 914 and 917.

Olin,

Thanks for the clarification. It was my mistake not to actually look at
the pinouts themselves (as opposed to just the device lists). From the
schematics of the qprot2 it looks like I should be able to recover port
bits RA6 and RA7 if I use the internal clock - at least if I don't mind
22pF to ground, or can cut these. Also, do you sell 5 pin ICSP
connectors of know of a reasonable source?

Thanks

Yes, the 22pF caps are easy to lift since they are only 0805 surface mount
parts.  Heat one end nicely with a soldering iron, then the other, then go
back to the first quickly and flick the part right off.  I had considered
leaving just pads, but then someone would have to find and install the right
caps.  Making them thru hole would have added manual work to the assembly
process.  On ballance, installing them but letting them be easily removed
seemed like the best answer.  Note you'd have to do that too if you wanted
to use a ceramic resonator instead of a crystal.

I don't sell any ICSP connectors.  However the board comes with a RJ-12 jack
connected to the programming lines ready for a ICD-2.  Since the ICD-2 is so
common, many programmers also adopt this connection scheme.  Most comsumer
electronic stores can sell you RJ-12 plugs, the crimper, and a length of
compatible 6 conductor "phone" cable.

Olin,

Thanks for the info. Removing the caps is a good approach, and I'll
crimp an RJ-12 for ICSP. Going off-list for the rest.
