PS DDR4 SODIMM Socket
[Figure 2, callout 2]
The PS-side memory is wired to the Zynq UltraScale+ RFSoC DDRC Bank 504 hard memory
controller. A 64-bit single rank DDR4 SODIMM is inserted into socket J48. The ZCU670 is
shipped with a DDR4 SODIMM installed:
• Manufacturer: Micron
• Part Number: MTA4ATF51264HZ-2G6E1
• Descripon:
○ 4 GByte DDR4 260-Pin SODIMM
○ Single Rank (x 16-bit components)
○ 512 Mb x 64-bit
○ 2666 MT/s
The ZCU670 ZU67DR RFSoC (ZU67DR supports 2400MT/s) PS DDR interface performance is
documented in the Zynq UltraScale+ RFSoC Data Sheet: DC and AC Switching Characteriscs
(DS926).
The ZCU670 DDR4 SODIMM interface adheres to the constraints guidelines documented in the
PCB guidelines for DDR4 secon of the UltraScale Architecture PCB Design User Guide (UG583).
The DDR4 SODIMM interface is a 40Ω impedance implementaon. Other memory interface
details are also available in the UltraScale Architecture-Based FPGAs Memory IP LogiCORE IP
Product Guide (PG150).
For addional details, see the Micron MTA4ATF51264HZ-2G6E1 data sheet on the Micron
Technology website.
The detailed RFSoC connecons for the feature described in this secon are documented in the
ZCU670 board XDC le, referenced in Appendix B: Xilinx Design Constraints.
