The PCI-X 740 is an Intelligent GbE Controller used in embedded and real time systems to help offload the system's host processor of LAN protocol, security, and monitoring functions.

The PCI-X 740 features Intel's new XScale 80331 with 667 MHz ARM Core, PCI-X Bridge, and support for 333 MHz DDR SDRAM. The PCI-X 740 two Gigabit Ethernet port configured as copper (Tx) or fiber optic (Sx/Lx). The PCI-740 is supported by VxWorks with a high performance Zero-Copy TCP Stack, TimeSys Linux, and Cyclone's Breeze Development Environment.
