Übersicht

Description

- LAN7800T-I/VSX is a USB 2.0 to 10/100 Ethernet controller from Microchip (SMSC) that provides a complete Ethernet NIC with an integrated MAC and PHY.
- It enables an embedded processor to add Ethernet connectivity by acting as a USB Ethernet device; USB 2.0 High‑Speed (480 Mbps) interfaces to the host, while the MAC/PHY handles 10/100 Ethernet.
- Features include support for 10/100 Mbps, auto-negotiation, and full/half‑duplex operation (MDI/MDIX as per design). It’s designed for embedded/industrial use.
- The suffix I/VSX indicates industrial-temperature capability (I) and a RoHS/packaging variant (VSX); always verify exact temperature range and package in the datasheet.
- Driver support exists for major OSes (e.g., Linux via lan78xx driver, Windows/macOS), making it suitable for USB Ethernet dongles, embedded boards, and network-enabled devices.
Note: For precise electrical specs, buffers, and host interface details, consult the LAN7800T-I/VSX datasheet and packaging documentation.
