PS-Side: DDR4 SODIMM Socket

[Figure 2-1, callout 2]

The PS-side memory is wired to the Zynq UltraScale+ DDRC bank 504 hard memory controller. The PS-side memory interface supports a 260-pin DDR4 SODIMM socket J1. The ZCU106 is shipped with a DDR4 SODIMM installed:

  • Manufacturer: Micron
  • Part Number: Previous P/N MTA8ATF51264HZ-2G6B1 (now EOL); New P/N MTA4ATF51264HZ-2G6E1 (in production)
  • Description:
    • 4 GB DDR4 SODIMM, 260-pin
    • Single rank, x16 b components
    • 512 Mb x 64-bit
    • Up to DDR-2666

The ZCU106 XCZU7EV FFVC MPSoC PS DDR interface performance is documented in the Zynq UltraScale+ MPSoC Data Sheet: DC and AC Switching Characteristics (DS925) [Ref 2].

The ZCU106 supports full power-off suspend mode where only the system controller and the PS-side DDR4 SODIMM memory are powered. The DDR4 memory is kept in a self-refresh state and has its reset input controlled by the system controller such that the memory is not reset when waking-up from suspend mode. DDR4 SODIMM socket J1 connections are listed in Table 3-3.

The ZCU106 DDR4 SODIMM interface adheres to the constraints guidelines documented in the "PCB Guidelines for DDR4" section of the UltraScale Architecture PCB Design Guide (UG583) [Ref 4]. The DDR4 SODIMM interface is a 40Ω impedance implementation. Other memory interface details are also available in the UltraScale Architecture FPGAs Memory Interface Solutions Guide (PG150) [Ref 5].
