Hi I`m thinking of using the MK66FN2M0VLQ18 in a project and need to add SDRAM but I`m a bit confused as I cannot find any examples. It seems that Databus 0 - 15 is not available on FB_AD0-15 as it is used for the address lines - Do I need to use latches to multiplex the data bus with the address lines?
Any help would be greatly appreciated
Hi,
I have checked the data sheet of MT48LC8M16A2 – 2 Meg x 16 x 4 Banks, this is the parameters:
row addressing:4K A[11:0]
column addressing:512 A[8:0]
bank addressing:4 BA[1:0]
You have to use the Table 35-8. SDRAM Controller to SDRAM Interface (16-Bit Port, 9-Column Address Lines) in RM of K66, the data bus is hooked to the High half word, I think your connection is okay. but I do not check the pin assignment.
