Propeller P8X32A?

Found the downside!

If you hook up the chip like it shows in every "minimum breadboard" sample Parallax puts out, it very quickly burns out the PLL used to multiply the crystal input. Doh! In case anyone decides to try this thing, you absolutely must connect ALL ground and ALL power pins together externally with as short a connection as possible. Additionally, decoupling ceramic capacitors are all-but-required across the power pins as close to the chip as you can manage. Crap design if you ask me, especially without mentioning these needs in the documentation.

Thankfully, it'll still work at slower clock speeds or with an external clock source so I don't have to toss this one and find another chip, yet.
