LAN8742AI-CZ

Product Overview

The LAN8742AI-CZ from Microchip Technology is a surface-mount transceiver intended for MII and RMII interface applications. It provides full-duplex operation with a 100 Mbps data rate and a 1/1 driver/receiver configuration. The device operates from a 1.6 V to 3.6 V supply and is specified for an operating temperature range of -40°C to 85°C. It is offered in a 24-VFQFN exposed pad package with 24-SQFN 4x4 dimensions.

Key Features

• MII and RMII protocol support
• Full-duplex transceiver operation
• 100 Mbps data rate
• 1/1 driver and receiver configuration
• 1.6 V to 3.6 V supply range
• -40°C to 85°C operating temperature range
• Surface-mount 24-VFQFN exposed pad package
• 24-SQFN 4x4 package

Applications

• Embedded devices requiring MII or RMII transceiver connectivity at 100 Mbps
• Full-duplex data links in systems operating within a -40°C to 85°C range
• Compact surface-mount boards using a 4x4 24-VFQFN exposed pad package

Design & Procurement Notes

Design considerations should confirm that the host interface matches either MII or RMII signaling and that the system can provide a supply voltage within the 1.6 V to 3.6 V range. The full-duplex 100 Mbps data rate and 1/1 driver/receiver configuration define the transceiver's functional role in the link. Board layout should account for the surface-mount 24-VFQFN exposed pad package and the 4x4 package dimensions, including handling of the exposed pad. The -40°C to 85°C operating temperature range should be checked against the intended environmental conditions. The 24-VFQFN exposed pad package supports surface-mount assembly.
