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: http://www.keil.com/mcb2100/mcb2100-schematics.pdf Get some ideals there. Good luck!!! Greg Deuerling Fermi National Accelerator Laboratory

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.
