MCF5329 DDR SDRAM / FB question

GLN — Mon, 10 Jul 2006 18:56:32 GMT

Hi,

I design a board with the MCF5329 and DDR SDRAM. The DDR SDRAM addres bus and data bus works at 2.5V levels. What levels does the FlexBus work? And at what levels does the other IO's work like the UART, FEC, ...

Thanks at advance

Hi GLN,

Sorry for the confusion. We are working on clarifying this in the electrical specs, but you can currently find the assigned voltage rails for each signal (I/O) in the Chapter 2 "Signal Descriptions" portion of the of users/reference manual. Look in the sixth column (heading: Voltage Domain). It should have something like EVDD or SDVDD. These will correspond to voltage domains in the electrical specs.

Hope this helps.
