LAN7850T-I/8JX

Controllers Overview

The LAN7850T-I/8JX is a Hi-Speed USB 2.0 to 10/100/1000 Ethernet controller manufactured by Microchip Technology, designed for industrial temperature ranges (-40°C to +85°C). It integrates a Gigabit PHY with HP Auto-MDIX, an Ethernet MAC supporting full-duplex operation, and a USB 2.0 device controller compliant with the USB 2.0 standard. The component operates within a voltage range of 2.97 V to 3.63 V, drawing up to 60 mA during operation. Data transfer rates include 12 Mb/s and 480 Mb/s via USB, alongside 10BASE-T, 100BASE-TX, and 1000BASE-T Ethernet speeds. It utilizes a 56-pin SQFN package (8 x 8 mm) and supports HSIC interfaces.

Controllers Feature Summary

• Integrates a Gigabit Ethernet PHY with auto-negotiation and HP Auto-MDIX capabilities
• Supports Energy Efficient Ethernet (IEEE 802.3az) and Wake on LAN functionality
• Includes One Time Programmable memory for configuration without external EEPROM
• Provides NetDetach feature for automatic USB attachment based on cable status

Controllers Applications

• Automotive Infotainment Systems
• Notebook and Tablet Docking Stations
• USB Port Replicators

• Embedded Systems and Consumer Electronics Devices

Controllers Procurement Notes

Verify the specific suffix 'T' indicates reel packaging when ordering. Confirm the '-I' designation matches the required industrial temperature range for your application environment. Ensure compatibility with existing design constraints regarding the 56-pin SQFN footprint and power supply requirements before finalizing procurement decisions.

Controllers Selection Notes

Select this component when a single-chip solution for USB 2.0 to Gigabit Ethernet conversion is required in industrial environments. Consider the integrated PHY and MAC features to reduce external component count. Verify driver support for target operating systems such as Windows, Linux, or uBoot if software integration is planned.

Controllers Part Context

This part belongs to the LAN7850 series from Microchip Technology, which offers USB to Ethernet bridge solutions. The LAN7850T-I/8JX specifically denotes the industrial temperature variant packaged in reels. It serves as a connectivity interface for devices requiring high-speed data transfer between USB hosts and Ethernet networks.

Controllers Replacement Considerations

LAN7850-I/8JX is a verified alternative offering identical electrical specifications but packaged in trays instead of reels.
