P Btcor feir Intel Ethernet Controller I225 PCI Express multi-gigabit Ethernet controller supporting mobile, desktop, workstation, value-server, or embedded space-constrained designs. Key Features Overview PCI Express 3.1 (5GT/s) x1 host This PCI Express controller with Base-T copper networking interface, interface provides compact, single-port integrated multi-gigabit (up to 2.5G) - MDI (Copper) standard IEEE 802.3 MDI (Copper) standard IEEE 802.3 Ethernet interface for 2500BASE-T, Ethernet interface up to 2.5Gb/s 1000BASE-T, 100BASE-TX, 10BASE-TE connections (IEEE 802.3, Time Sensitive Networking (TSN) 802.3u, 802.3ab). capability support The Intel Ethernet Controller I225 is designed for use on any mobile, Innovative power management features desktop, workstation, value-server, or industrial designs that have critical space constraints. The I225 can also support Intel vPro technology on Support for Intel Active Management Technology on systems enabled with specific Intel platforms and chipsets. Intel vPro technology The Intel Ethernet Controller I225 also supports the latest time sensitive networking (TSN) features, along with best in class power management and Operating System Support. duEnergy Efficient Ethernet (EEE) Filled with Performance Optimization Capabilities Supports the IEEE 802.3az EEE standard. During The Intel Ethernet Connection I225 includes advanced periods of low network activity, EEE reduces the power interrupt-handling features to reduce CPU overhead. consumption of an Ethernet connection by negotiating Other performance-enhancing features include with the switch port to transition to a low power idle offloading TCP/UDP (for both IPv4 and IPv6) checksum (LPI) state. calculations and performing TCP segmentation. This capability reduces power dramatically, saving power Advanced features such as Jumbo Frame support for on both the network and the switch ports. When extra-large packets and Receive Side Scaling (RSS) increased traffic is detected, the controller and the switch are also supported. Additionally, I225 builds on prior quickly come back to full power to handle the increased controller solutions to add Time Sensitive Networking traffic. EEE is supported for 2500BASE-T, 1000BASE-T (TSN) features including IEEE 802.1Qbu, 802.3br, and 100BASE-TX. 802.1Qbv, 802.1AS-REV, 802.1p/Q, and 802.1Qav on select operating systems. These features support advanced time critical, and synchronized applications Flexible Design Configurations prevalent in audio/video, embedded, and industrial The I225 can be used for server system configurations applications. such as rack-mounted or pedestal servers, in an add-on NIC, and in LAN on Motherboard (LOM) designs. Advanced interrupt-handling features manage multiple interrupts simultaneously. Combining Intel Ethernet Controller I225-V/LM supports interrupt-handling features with intelligent filtering, commercial temperature ranges of 0 C to 70 C ordering, and directing packets to specific queues and up to 2500BASE-T. cores, enables load-balancing network traffic flows to Intel Ethernet Controller I225-IT supports extended improve throughput in multi-core platforms. temperatures for embedded applications with Other performance-enhancing features include IPv4 commercial temperature ranges of -40 C to 70 C and IPv6 checksum offload, TCP/UDP checksum offload, up to 2500BASE-T and -40 C to 85 C up to extended Tx descriptors for more offload capabilities, 1000BASE-T. up to 256 KB TCP segmentation (TSO v2), 40 KB packet buffer size, and 9.5 KB Jumbo Frame support. Manageability Support The Intel Ethernet Controller I225 provides Other Advanced Features Intel Active Management Technology support Flexible Filters when connected to a system with Intel vPro Supports a total of 32 individually configurable flexible technology, directly as LAN on motherboard, or via a filters. Filters can be used for wake-up or proxying when Thunderbolt device. in D3 state or for queueing when in D0 state. Secure Flexible Firmware Architecture Flexible Firmware Architecture with Secure NVM Update protects the flash from external unauthorized software programming. The Intel Ethernet Controller I225 also supports Dynamic Firmware Updating that enables Firmware Updates without the need for a system reboot. Software Definable Pins Four Software Definable Pins (SDPs) enable additional design customization for embedded platforms. SDPs can be used for IEEE 1588 auxiliary device connections, to enable/disable the device, and for other miscellaneous hardware or software-control purposes. These pins can be individually configured to act as either standard inputs, General-Purpose Interrupt (GPI) input or output pins, as well as the default value of all pins configured as outputs. One SDP is dedicated, and three are shared with the JTAG interface. 2 2
