PCH-LP (UP3)

Flexible HSIO Lane Multiplexing in PCH-LP (UP3)

The 12 Flexible HSIO Lanes [11:0] on PCH-LP (UP3) support the following configurations:

  1. Up to 12 PCIe* Lanes
    • A maximum of six PCIe Root Ports (or devices) can be enabled
      • When a GbE Port is enabled, the maximum number of PCIe Root Ports (or devices) that can be enabled reduces based off the following:

        --> Max PCIe Root Ports (or devices) = 6 - GbE (0 or 1)

    • PCIe Lanes 1-4 (PCIe Controller #1), 5-8 (PCIe Controller #2), and 9-12 (PCIe Controller #3) must be individually configured.
  2. Up to two SATA Lanes
    • A maximum of two SATA Ports (or devices) can be enabled.
  3. Up to four USB 3.2 Gen 1x1/2x1 Lanes
    • A maximum of four USB 3.2 Gen 1x1/2x1 Ports (or devices) can be enabled.
    • USB 3.2  Gen 1x1 = 5 GT/s
    • USB 3.2  Gen 2x1 = 10 GT/s
  4. Up to three GbE Lanes
    • A maximum of one GbE Port (or device) can be enabled.
