LAN8720A-CP

Product Overview

The LAN8720A-CP from Microchip Technology is an active 2/2 transceiver for MII and RMII protocol interfaces. The device supports full-duplex operation at a 100 Mbps data rate and is supplied in a 24-QFN-EP (4x4) surface-mount package. Its specified supply voltage range is 1.6 V to 3.6 V, and its operating temperature range is 0°C to 85°C. The component is suitable for designs that require a compact transceiver interface between host logic and an MII or RMII signal path.

Key Features

• MII and RMII protocol support with 2 drivers and 2 receivers
• Full-duplex transceiver operation at 100 Mbps
• 1.6 V to 3.6 V supply voltage range
• 0°C to 85°C operating temperature range
• 24-VFQFN Exposed Pad package, 24-QFN-EP (4x4), surface-mount
• Microchip Technology flexPWR series, active lifecycle status

Applications

• Embedded networked controllers that connect a host-side processor to an MII or RMII interface
• Compact communication modules requiring full-duplex 100 Mbps data paths on surface-mount boards
• Low-voltage interface circuits operating from a 1.6 V to 3.6 V supply

Design & Procurement Notes

Designers selecting the LAN8720A-CP should confirm that the host-side interface uses MII or RMII and that the required data rate is 100 Mbps. The 1.6 V to 3.6 V supply range and 0°C to 85°C operating range should be checked against the final board environment and power architecture. Because the device is a surface-mount 24-QFN-EP (4x4) exposed-pad package, layout and thermal design should account for pad access, soldering, and exposed-pad handling. The active lifecycle status supports current design use, while procurement should verify the exact package and footprint before finalizing the bill of materials.
