LAN8720AI-CP-TR LAN8720AI-CP-TR Microchip 10/100 Ethernet PHY Transceiver 24-Pin 3.3V QFN, 1.6 V 100 Mbps RMII

The LAN8720AI-CP-TR from Microchip Technology is a compact, low-power 10BASE-T/100BASE-TX Ethernet physical layer transceiver designed for embedded networking, industrial control, consumer electronics, and enterprise equipment. It provides a standard RMII interface for connection to an Ethernet MAC and supports both 10 Mbps and 100 Mbps Ethernet operation.

This device integrates Microchip’s flexPWR® technology, an internal voltage regulator, and ESD protection features to help reduce external BOM requirements. The LAN8720AI-CP-TR is supplied in a 24-QFN / 24-SQFN 4 × 4 mm package and is offered in tape-and-reel packaging, making it suitable for automated PCB assembly and volume production.

Key Features

Product Description

The LAN8720AI-CP-TR is a high-performance Ethernet PHY IC used to add wired Ethernet connectivity to microcontrollers, processors, SoCs, and embedded control boards. It is especially useful in designs that already include an Ethernet MAC but require an external physical layer device for connection to twisted-pair Ethernet cabling.

With support for 10BASE-T and 100BASE-TX, the LAN8720AI-CP-TR enables reliable Fast Ethernet communication in compact PCB layouts. Its small 24-pin QFN package helps save board space, while the low-power architecture makes it suitable for embedded and always-on applications. The device also supports HP Auto-MDIX, allowing automatic detection and correction of cable connection types, which helps simplify Ethernet port design and improve system usability.

Applications

• Embedded Ethernet interfaces
• Industrial control systems
• IoT gateways and connected devices
• Networked measurement equipment
• Consumer electronics
• Security and access control devices
• Building automation systems
• Ethernet-enabled MCU and processor boards
• Test and monitoring equipment

Summary

LAN8720AI-CP-TR is a compact Microchip 10/100 Mbps Ethernet PHY transceiver for embedded systems requiring reliable wired Ethernet connectivity. With RMII interface support, low power consumption, HP Auto-MDIX, wide operating temperature range, and tape-and-reel packaging, it is well suited for industrial, consumer, and networking applications.
