Description
The LAN8720AI-CP-TR-ABC is a low-power, single-port 10/100 Ethernet PHY transceiver from Microchip. It supports MII (Media Independent Interface) and RMII (Reduced MII), making it ideal for embedded systems requiring Ethernet connectivity.
### Key Features:
- Low power: Operates at 1.8V–3.3V, reducing energy consumption.
- Small footprint: 4x4mm QFN-24 package, suitable for space-constrained designs.
- Auto-negotiation: Supports 10BASE-T & 100BASE-TX with automatic speed detection.
- Industrial-grade: Extended temperature range (-40°C to +85°C) for harsh environments.
- Integrated termination resistors: Simplifies PCB design.
### Applications:
- IoT devices, industrial controllers, and consumer electronics requiring Ethernet.
The -TR-ABC suffix indicates tape-and-reel packaging for automated assembly. For detailed specs, refer to the Microchip datasheet.
