pcb layout of the LPC2294

pcb layout of the LPC2294

2005-02-16 by kn_lamb

I am doing a pcb layout of the LPC2292 for the first time. What is 
the proper way to design the pcb with this part? I appreciate anyones 
help in this area.

Thanks,

Ken

I've done LPC2194 and LPC2294 designs and just do the stuff you should do
on every design:

Keep the xtal close to the uC and on the same layer as the uC.
Put a .1 or .01 uF cap on EACH power pin.
Put a 10uF or two tant. cap on the board.
Keep the power traces short as possible.
Study the LPC2xxx user manual for any pins that need pulled up or down.

Keil has a schematic for their eval board online:

Get some ideals there.
Good luck!!!

And, if circuit is more complicated and PCB has more
than one layers, least layer (or maximum layer area -
poly) each PC board must be dedicated to ground
planes.
Do initial layout with split analog and digital ground
planes.
