Low Profile Mezzanine Module for CompactPCI® Serial CPU Cards

Available as a mezzanine add-on expansion board e.g. to the SC5-FESTIVAL and successor CPU carrier cards, the main purpose of the S83-P6 is to provide a Solid State Drive mass storage solution, and in addition to supply the backplane with four Gigabit Ethernet ports.

The S83-P6 is equipped with an M.2 PCIe® Gen4 x4 socket, suitable for an NVMe type SSD module. The maximum PCIe® data transfer rate depends on the particular CPU carrier card (16GT/s require SC9-TOCCATA).

Four discrete Gigabit Ethernet controllers are provided on-board, for CompactPCI® Serial backplane communication via the P6 connector according to the 2.5GBASE-T interface standard. The S83-P6 is equipped in addition with a Type-C front port for attachment of an USB device or DisplayPort monitor.

The Intel® I226-IT 2.5GbE controllers support latest networking features and are backward compatible to 1000BASE-T as originally specified by the CompactPCI® Serial specification. With a suitable Ethernet enabled CompactPCI® Serial backplane, both networking architectures are supported, either single star or full mesh.

The S83-P6 connects to the mezzanine expansion connectors HSE1 and HSE2 of the CompactPCI® Serial CPU carrier board, maintaining the 4HP (20.32mm) total assembly height
