It seems like you may hint me where to find it, may you? Sorry, I don't have anything in particular, just bits I've picked up talking to CF manufacturers. Basically, a CF card is a flash ROM array attached to a little microcontroller with an IDE interface. The large manufacturers generally have custom controllers. A basic block diagram is on page 3 (physical page 19) of the CompactFlash spec, available from http://www.compactflash.org/cfspc3_0.pdf
