Hi all,
i would seek advise on routing of high speed board.
My board have 8 layers one MCU --MC9328MX21VM, MAPBGA-289.. 2 SDRAM and 1 flash..plus other components
How looks your layer stack and how exactly did you route data and address bus (on which layers) ?
After changing a flash component on my board, it seems that the whole board is unstable. My engineer suspects (issit true??) its the 31 data lines and 25 address pins. So anyone know in what way will routing help to stablize the board...any references?
Thanks all
