The PME-P is a single site PCIe (PCI Express) to PCI/PCI-X adapter board. It enables a x1, x2, or x4 PCIe board to be plugged into any Universal PCI 2.3 32 or 64-bit PCI or PCI-X slot running at 33-133MHz with 5V I/O tolerant PCI signaling. XMC boards with a x8 PCIe width on Pn5 can also be installed but only a x4 path is supported.

The PME-P features the Pericom PI7C9X130 PCI Express to PCI-X Reversible Bridge. Among others, the PI7C9X130 is compliant with the PCI Express Base Specification, Revision 1.1 and the PCI Express to PCI/PCI-X Bridge Specification, Revision 1.0. PI7C9X130 supports transparent and non-transparent mode of operations.

The PI7C9X130 is used on the PME-P as a reverse bridge (PCIe to a PCI/PCI-X host system). In reverse bridge mode, PI7C9X130 has a 64-bitPCI-X upstream port and an x4 PCI Express downstream port (2.5Gb/s data rate). PI7C9X130 configuration registers are backward compatible with standard PCI bridge software and firmware.

To aid in debugging, the PME-P has Test Point pins and/or LED indicators for all major on-board power sources. JTAG access is supported for both an external connector and via the PCI bus.
