LAN8720A-CP-ABC

Product Overview

The LAN8720A-CP-ABC from Microchip Technology is a surface-mount transceiver intended for Ethernet physical-layer interfacing using MII or RMII protocols. It supports full-duplex operation with two drivers and two receivers at a 100 Mbps data rate. The device operates from a 1.6 V to 3.6 V supply and is specified for an operating temperature range of 0°C to 85°C. It is supplied in a 24-SQFN (4x4) package with an exposed pad for embedded board layouts that require a media-independent interface connection.

Key Features

• MII and RMII protocol support
• 2/2 driver and receiver configuration with full duplex
• 100 Mbps data rate
• 1.6 V to 3.6 V supply range
• 0°C to 85°C operating temperature range
• 24-SQFN (4x4) surface-mount package with exposed pad

Applications

• Embedded Ethernet physical-layer interfacing
• Networked microcontroller board design
• Communications hardware requiring MII or RMII media-independent interfaces

Design & Procurement Notes

When selecting the LAN8720A-CP-ABC, confirm that the host interface supports either MII or RMII and that the board stack-up provides a supply within the 1.6 V to 3.6 V range. The 24-SQFN (4x4) package with an exposed pad requires surface-mount pad planning and adequate land pattern definition for reliable assembly. Because the device is rated for 0°C to 85°C operation, system thermal conditions should remain within that range. The 2/2 driver and receiver arrangement and full-duplex 100 Mbps data rate should be matched to the intended Ethernet physical-layer topology rather than assumed from the package size or series name. Design review should also verify interface timing and power sequencing against the final schematic before layout release.
