• Speedgrade 2 and 3 devices: up to 2400 Mbit/s (1200 MHz)
Hence, the maximum memory bandwidth on the Mercury XU5 SoC module for the DDR4 SDRAM (PL) is:
• Speedgrade 1 devices: up to 2133 Mbit/s × 16 bit = 4266 MB/sec
• Speedgrade 2 and 3 devices: up to 2400 Mbit/s × 16 bit = 4800 MB/sec
Note that for MPSoC low power mode (at 0.72 V) the DDR speed is lower than mentioned above. For details,
refer to the Zynq UltraScale+ MPSoC, DC and AC Switching Characteristics [21].

Warning!
Other DDR4 memory devices may be equipped in future revisions of the Mercury XU5 SoC module.
Please check the user manual regularly for updates. Any parts with different speed bins or temperature
ranges that fulfill the requirements for the module variant may be used.
2.16.2 Signal Description
Please refer to the Mercury XU5 SoC Module FPGA Pinout Excel Sheet [4] for detailed information on the
DDR4 SDRAM connections.
2.16.3 Termination
Warning!
No external termination is implemented on the Mercury XU5 SoC module. Therefore, it is strongly
recommended to enable the on-die termination (ODT) feature of the DDR4 SDRAM device.
