MCHPLAN7800-I/VSX
Overview
The LAN7800-I/VSX is a high-performance USB 3.1 Gen 1 to 10/100/1000 Ethernet bridge with an integrated Gigabit PHY. It provides a single-chip solution for adding high-speed networking to embedded systems via a SuperSpeed USB interface, supporting industrial temperature ranges from -40C to 85C.
Why Choose This Part
The device features extensive hardware offload engines for IPv4/IPv6 checksums and 9 KB jumbo frame support to reduce host CPU overhead. It includes specialized power management like NetDetach, which automatically manages USB state based on Ethernet cable connectivity, and supports Energy Efficient Ethernet (IEEE 802.3az).
Applications
Key Specifications
Getting Started
Designers can evaluate the chip using the EVB-LAN7800-LC evaluation board. Hardware configuration is handled through an internal 1 KB OTP memory or an external 512-byte EEPROM, and Microchip provides drivers for major operating systems including Windows, Linux, and macOS.
