SAM3U interface with sdram?

Thu Feb 02, 2012 7:37 am

Can I interface SDRAM with SAM3U? All the PSRAM are in BGA format and I have no experience with BGA prototyping.

If it is not possible, then I have to use the SAM7SE?

Does it have an SDRAM controller? I think not.

You could presumably cobble together some older 3V SRAM parts together, if you can't get the density you want you could add some decode logic.
