A.5. Memory Interfaces

FPGA dedicated external memory interface (SO-DIMM)

Intel is designing and verifying a customized QDRIV SODIMM module which fits with the 260-pin DDR4 SODIMM socket. Both DDR4 and QDRIV protocols can be tested on one single socket CON1. A long guide pin assembled on the customized QDRIV module slides in the guide hole which is reserved on Intel® Agilex™ F-Series Transceiver-SoC Development Kit. This mechanical design avoids a wrong plug between customized QDRIV SODIMM and unsupported mother board. Only Intel® Agilex™ FPGA fabric can access this external memory interface.

FPGA and HPS shared external memory interface (DDR4)

DDR4 component interface is a 72 bit, single rank configuration based on x16 component. It runs at 2400 Mbps. Footprint supports both MT40A1G16RC-062E and MT40A1G16KNR-062E component. By default, the component is: MT40A1G16RC-062E. Both Intel® Agilex™ FPGA fabric and HPS can access this external memory interface, however they cannot be accessed at the same time.
