DDR3 Memory (VLP MINIUDIMM)
With a 244 pin VLP MINIUDIMM module, connected to the Kintex-7 FPGA, the
following transfer speeds can be expected:
Speed Grade -3
1866Mb/s
Speed Grade -2
1866Mb/s
Speed Grade -1
1600Mb/s
The VLP MINIUDIMM interface is connected to IO Banks on the Kintex-7 FPGAs
and uses a 1.5V switching power supply for V
DD
and V
CCIO
. V
TT
and V
REF
are powered
from a separate linear power supply set at 0.75V. DDR3 SDRAM modules are available
from
Micron
, example part number for a 2GB (256Mbx72) 244-pin VLP
MINIUDIMM SDRAM module is:

DDR3 SDRAM Memory Interface Solution
The Kintex-7 FPGA memory interface solutions core is a pre-engineered controller and
physical layer (PHY) for interfacing Kintex-7 FPGA user designs to DDR3 SDRAM
devices.
The Memory Interface Generator (MIG) is a self-explanatory wizard tool that can be
invoked under the CORE Generator software. Xilinx published a memory application
note; please refer to
UG-586 – 7-Series FPGAs Memory Interface Solutions, User Guide
