Chapter 3: Board Component Descriptions
DDR4 DIMM Memory
[Figure 2-1, callout 2, 3, 4, 5]
Four independent dual-rank DDR4 interfaces are available on the VCU1525 board. The
VCU1525 board is populated with four socketed single-rank Micron
MTA18ASF2G72PZ-2G3B1IG or Samsung M393A2K40BB1-CRC 16GB DDR4 UDIMMs. Each
DDR4 is 72-bits wide (64-bits plus support for ECC).
Memory interface-to-FPGA bank assignment is shown in Table 3-1. The DDR4 0.6V V
TT
termination voltages are sourced from four independent TI TPS51200DR regulator circuits.
The detailed connections between the four DDR4 DIMM sockets and the
XCVU9P-L2FSGD2104E FPGA banks are listed in Appendix A, Master Constraints File Listing.
The VCU1525 DDR4 memory interfaces adhere to the constraints guidelines documented in
the "DDR3/DDR4 Design Guidelines" section of the UltraScale Architecture-Based FPGAs
Memory IP LogiCORE IP Product Guide (PG150) [Ref 3]. The VCU1525 board DDR4 memory
interfaces are 40 Ω impedance implementations.
For more details about the Micron DDR4 DIMM, see the Micron MTA18ASF2G72PZ-2G3B1IG
data sheet at the Micron website [Ref 4].
For more details about the Samsung DDR4 DIMM, see the Samsung M393A2K40BB1-CRC
data sheet at the Samsung website [Ref 5].
Quad SPI Flash Memory
[Figure 2-1, callout 6]
Two Quad Serial Peripheral Interface (SPI) flash memory devices of the same type and wired
in parallel are provided on the VCU1525 board (U17 and U58). A field effect transistor (FET)
switch structure (U57 and U61) implements a chip-select enable mechanism, controlled by
the MSP432 board management controller (BMC). Only one Quad SPI device can be
enabled at a time.
