P2ME2 - (was Bypass capacitors needed for P2)
I'm currently laying out my own P2 board to replace the now absent P2D2 I'd otherwise planned to use and am having issues fitting in a total of 32 bypass caps just for the P2 on the PCB, given I will likely have to hand solder them and really don't want to go below 0603 sized parts to help save my eyes.
In practice would a P2 really need that many bypass capacitors if the supply is kept very close to the P2?
In this case the core voltage is fed from a ring around the inner ground square and probably only needs to travel about 5mm from the regulator outside the ring. A ground plane is on the rear side and the bypass caps are wired directly to the inner square on the rear side with a via on each 1.8V pin. The 3.3V bypass caps are on the same side as the P2 but it's a bit of a squeeze to try to fit them all in with all the signals fanning out between them but I'm still trying and may get there anyway with 6/6 design rules. I'm not planning to spend weeks laying out this board to make it fit nicely. It's likely a one off.
If any caps need to get removed for space reasons, which supply, 3.3V or 1.8V, would the impact typically be less noticeable?
Update: forgot to mention, this is a two layer board which is why it is more challenging.
