LAN8720 module Ethernet transceiver RMII interface development board
LAN8720 module Ethernet transceiver RMII interface development board
Product Introduction
This product is a low-power 10BASE-T/100BASE-TX physical layer (PHY) transceiver with variable I/O voltage, compliant with the IEEE 802.3-2005 standard. It includes a full duplex 10-BASE-T transceiver that supports 10Mbps (10BASE-T) and 100Mbps (100BASE-TX) operations. Implement automatic negotiation to automatically determine the best possible speed and duplex operation mode. The module supports communication with Ethernet MAC through standard RMII interface. HP Auto MDIX supports the use of direct or crossover LAN cables.
Product Application
Embedded WEB Server
Product Parameter
High performance 10/100MBP Ethernet transceiver (PHY)
Low power design, can be powered by a single 3.3V power supply
By adopting RMII interface, the control pins of MCU are greatly reduced
Chip integrated 1.2V voltage regulator
I0 voltage range:+ 1.6V to+3.6V
