On request, the
NAT-AMC-ZYNQUP-FMC
can be equipped with several memory extension
cards. Depending on the target application, different memory types can offer advantages;
QDR4 and RLDRAM3 memory offers low latency random access, which is useful for applications
requiring RAM look up tables (LUTs).
Currently, the
NAT-MEM-DDR4-2x8
(Dual Channel, x8, 2 GB DDR4 memory card) is available.
The memory to FPGA pin assignment is described in the following tables.
