# LAN8720A-CP-TR-ABC (Component)
## Description
Small Footprint RMII 10/100 Ethernet Transceiver with HP Auto-MDIX Support
LAN8720A-CP-TR-ABC is a low-power, single-port 10BASE-T/100BASE-TX Ethernet Physical Layer (PHY) transceiver from Microchip Technology. It is designed to connect a microcontroller, processor, or Ethernet MAC to a standard Ethernet network through an RMII (Reduced Media Independent Interface). The device is widely used in embedded networking applications such as industrial controllers, IoT gateways, IP cameras, networked printers, routers, and ESP32-based Ethernet designs.
Key Features
Single-chip 10/100 Mbps Ethernet PHY
Supports both 10BASE-T and 100BASE-TX Ethernet operation.
RMII Interface
Reduced pin-count interface for easy connection to Ethernet MACs and microcontrollers.
IEEE 802.3 / 802.3u Compliant
Fully compliant with Fast Ethernet standards.
HP Auto-MDIX Support
Automatically detects and configures straight-through or crossover Ethernet cables.
Auto-Negotiation
Automatically selects the best available speed and duplex mode.
Flexible I/O Voltage
Supports LVCMOS I/O voltages from 1.6 V to 3.6 V, simplifying interfacing with different processors.
Integrated 1.2 V Regulator
Allows operation from a single 3.3 V supply, reducing external components.
Low-Power Architecture
Features multiple power-saving modes through Microchip's flexPWR® technology.
Built-in Diagnostics and Reliability Features
Loopback modes, automatic polarity correction, link-status monitoring, and wake-up detection.
Compact Package
Available in a 24-pin SQFN/QFN (4 mm × 4 mm) package for space-constrained designs
