Reference Manual

Table 2–46

lists the DDR2 SDRAM DIMM component reference and manufacturing

information.

DDR2 SDRAM Devices

The board supports two independent 8-bit DDR2 SDRAM interfaces on the horizontal
I/O banks.

The target speed on the side bank is 300-MHz DDR.

Table 2–47

lists the DDR2 device A interface signals. JEDEC bus widths are used.

Table 2–47

also shows a summary of the required number of pins to support the

largest possible DDR2 devices available in a ×8 data configuration.
