Dear all,

I'm back again after unsubscribing over the Summer.

I've built a circuit around the 16F877 40 pin PIC using MPLAB and now
want to start fabricating boards. My problem is that size is important,
and I'd planned on using the Quad Flatpack package to save a bit of
space (since it uses 11 pins on each face to cram 44 pins onto a 10 mm
square surface mount) - so that I can get 8 channels of ADC.

I just spoke to Digi-Key and they told me that they have no stock of the
Quad Flatpack package - apparently it needs to be ordered from
Microchip.

I'm wondering if anyone has experience using these quad packages, and
whether it is as obscure as it sounds. Do you think I should abandon it
and use a standard rectangular 28 pin version (which will mean I will
have to reduce the number of ADCs to 5).

TIA!

Chris
