With the new offering, Microchip provides customers using PCIe Ethernet bridges design confidence through product longevity, worldwide technical support, design review services of final designs and fully released drivers for Linux® or Windows® operating systems. Microchip’s customer-driven obsolescence practice is a philosophy that helps to ensure that, for as long as demand exists for any product, Microchip will make efforts to continue to provide it.

A true single-chip solution, the LAN7430/1 family offers single 3.3V supply operation, removing the need for complex and costly power management support. Both devices integrate a JTAG (1149.1) Test Access Port (TAP) for enhanced test coverage. Microchip also offers LINK MD® diagnostics utilising Time Domain Reflectometry (TDR) to analyse the cabling harness, identifying and locating common cabling problems such as open circuits, short circuits and impedance mismatches.

The LAN7430 and LAN7431 are backed by Microchip’s free LANCheck® online design review service that reviews customer designs, ensuring that best design practices are used. Microchip’s MPLAB® Connect software tool is provided for programming One-Time-Programmable (OTP) memory, or the optional EEPROM memory, for easy device configuration. Microsoft Windows Hardware Quality Labs (WHQL) certified drivers are available along with Linux mainline kernel drivers for both networking and PTP and gPTP synchronisation. Evaluation boards (EVB-LAN7430 and EVB-LAN7431) are also available.

The LAN7430 is available in a 48-lead QFN package. The LAN7431 is available in a 72-lead QFN package.
