Microchip's LAN7430 is a PCIe 3.1 (at 2.5GT/s) to Gigabit Ethernet bridge, providing an ultra-high-performance and cost-effective PCIe to Ethernet connectivity solution.LAN7430 contains an integrated Ethernet PHY, PCIe PHY, PCIe endpoint controller,Ethernet MAC, Integrated OTP, JTAG TAP and EEPROM controller. The device supports 10BASE-T, 100BASE-TX and 1000BASE-T Ethernet with auto-negotiation, auto-polarity correction, HP Auto-MDIX† support and is compliant with IEEE 802.3/802.3u/802.3ab standards.

PCIe-based networking provides flexibility for the routing and placement of network connections anywhere in the system.Specific enhancements for PCIe LPSS (Low Power Sub-States) L1.1 and LPSS L1.2 have been integrated to lower system power consumption.LAN7430 is available with a wide range of drivers including Windows^®,Linux^®, and Pseudo Code for development towards RTOS.LAN7430 also supports Precision Time Protocol using industry standard 1588-2008 PTP.GPIOs are provided that can be software defined for this function.Included within this feature is a programmable timer compare output that can also be software configured.

The LAN7430 integrates all needed voltage regulators and requires only a single 3.3V supply.Further BOM savings can be realized through the integrated clock tree only requiring one external crystal or clock source.An EEPROM interface is provided although is not mandatory - an integrated OTP memory can provide for configuration data, further reducing system design cost and burden.

Multiple power management features are provided, including various low-power modes and Magic Packet™, Wake-on-LAN (WoL) and Link Status Change wake events.Microsoft Connected Standby (CS) and Always On Always Connected (AOAC) is also supported.These wake events can be programmed to initiate a PCIe beacon, and if desired, also generate a hardware PME event.

The device is available in commercial (0°C to 70°C) and industrial temperature range (-40°C to 85°C).

†HP Auto-MDIX eliminates the need for special "crossover" cables when connecting LAN devices together.
