spmp305x wiki is a wiki for this chip. Unfortunately it is heavily vandalised.

A specification of the chipset can be found at

Unfortunately no datasheet is available, which is a pity as this thing would be a very nice, ultra cheap linux box. also has a long thread on this chip and the players based upon it here
