Gigabit Ethernet Controller PMC – PMC401

A quad (4-port) 10/100/1000 Mbit Ethernet PMC based controller for use in embedded applications. The PMC401 contains four Intel 82574IT, low power single port Gigabit Ethernet controllers.

These controllers offer a lot of standard Ethernet related features, plus extra features like support for hardware-based time stamping, jumbo frames and host offloading features like IPv4 and IPv6 checksum.

The Ethernet controllers are transparently connected to the PMC PCI interface via a PLX PCI to PCIe bridge and PCIe switch. The PMC PCI interface is converted into a one lane 2.5Gbs PCIe for each controller.

The front panel has four RJ45 copper connectors with LEDs for a combined link/activity indication.

For each Ethernet controller is a bootflash chip available in which a bootloader may be programmed (bootloader not included).

The PMC401 is available in standard temperature, 0 to +60°C and industrial temperature, -40 to +85°C.

Driver support is included in most commonly used operating systems, contact us for further specific information regarding operating system and driver support.
