12.2.3.3. One 32-bit SDRAM channel

In this use case, the IOBank0 is configured to support a single 32-bit wide SDRAM channel using the MPFE block using IOBank0_P0. Since all eight IOBank0 IO12 channels are required, there is no support for direct fabric connection to the IOBank0 and choosing not to use the F2SDRAM port does not make them available. If available on the device, direct fabric connection to IOBank1 is supported.

The application may optionally use the F2H channel but choosing not to use F2H does not make any unused IO12 channels available to the fabric.

All read/write traffic between the CCU/NCORE and MPFE must occur on the DMI0 port. No other CCU/NCORE configurations are supported and can lead to unpredictable results.

This use case is supported by all members of the Agilex™ 5 family.

In this topology the following data paths occur:
  • F2H -> CCU_DMI0 -> IOBank0_P0 (32-bit HMC)
  • F2SDRAM -> IOBank0_P0 (32-bit HMC)
