Product Overview
The LAN8720A-CP-TR-ABC is a compact, low-power 10/100 Ethernet PHY transceiver from Microchip for cost & space-limited embedded networking systems. It adopts the RMII interface to cut pin counts vs traditional MII, and integrates Microchip FlexPWR® 1.2V LDO to support single 3.3V power supply and lower BOM cost. Built-in HP Auto-MDIX auto-corrects cable polarity without crossover cables. Packaged in thermal-enhanced 24-pin QFN, it’s ideal for IoT gateways, industrial controllers, IP cameras and network test instruments.
Core Advantages
Ultra-Compact and Reduced Pin Count
Utilizes a streamlined RMII interface implementation to cut down peripheral trace routing by up to 40% compared to standard MII networks, freeing up valuable microcontroller I/O pins for custom hardware execution.
Integrated 1.2V Linear Regulator
Features an onboard internal voltage regulator to supply the core logic components directly from the external 3.3V rail, simplifying multi-voltage trace topologies and shrinking overall discrete circuit complexity.
Advanced FlexPWR® Low Power Modes
Incorporates specialized power management modes, including low-current standby and Energy Efficient Ethernet (EEE) states, optimizing system thermal profiles and decreasing constant power drainage.
Seamless Cable Diagnostic Deployment
Supports robust HP Auto-MDIX configurations along with built-in loopback capabilities, allowing the transceiver to dynamically fix cross-wired cable errors and accelerate system initialization diagnostics.

Frequently Asked Questions
Q1: Is your currently available stock of the LAN8720A-CP-TR-ABC transceiver 100% genuine and original?
A: Yes, we guarantee that all LAN8720A-CP-TR-ABC components in our warehouse are 100% brand-new, factory-original products directly from Microchip Technology. Every batch is cataloged and packed inside anti-static ESD shielding bags under strict moisture sensitivity level (MSL) conditions.
Q2: What is the exact layout configuration meaning designated by the “TR” parameter suffix?
A: The “TR” designation in Microchip’s part-numbering matrix represents Tape and Reel packaging. This means the components are supplied on continuous carrier tapes wound onto standard reels, optimized for rapid pick-and-place operation on automated SMT assembly lines.
Q3: Do I need to supply an external 50 MHz clock signal when interfacing this PHY chip via RMII?
A: The LAN8720A is highly flexible. It can either generate the required 50 MHz RMII reference clock internally from an inexpensive 25 MHz crystal, or it can accept an externally derived 50 MHz clock trace on its REF_CLK pin from your host MCU or clock buffer.
Q4: How can our hardware design division request schematic design guides, IBIS simulation models, or ask for special volume pricing tiers?
A: Please complete our Quick Inquiry web form on this page with details about your project parameters. Our application support desk will process your inquiry and dispatch the available technical documentation package within 24 hours.
