I am currently designing a board for the DSP56724 and I want to include some SDRAM. Is there some reference design that shows how to interface the processor with sdrams? The datasheet (or reference manual) shows a configuration where the databus is 24bits and address and data lines are multiplexed. After all a quite unusual configuration so I like to have a look at a working design before I start. I saw somewhere that Freescale is offering a daughterboard for the 56720/4 but I could find a schematic, maybe someone could provide me with a link?
