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.
