Frequently Asked Questions

Q: What is the LAN8720 Ethernet Transceiver Module and what does it do?

A: The LAN8720 is a low-power 10/100 Mbps Ethernet PHY (Physical Layer Transceiver) module that uses the RMII interface to connect a microcontroller or embedded processor to a standard Ethernet network. It handles the physical layer signal processing, allowing your MCU to send and receive network data over a standard RJ45 connection.

Q: Which microcontrollers or development boards are compatible with the LAN8720 RMII module?

A: The LAN8720 is widely compatible with STM32-series microcontrollers (e.g. STM32F4, STM32F7), as well as other RMII-capable MCUs. It is commonly used in embedded server projects, IoT gateways, and development board Ethernet interface expansions. Its 1.6V–3.6V I/O range ensures compatibility with modern 3.3V and even some 1.8V systems.

Q: Does the LAN8720 module support Auto-MDIX?

A: Yes. The LAN8720 features built-in Auto-MDIX, which means it automatically detects the type of Ethernet cable connected (straight-through or crossover) and adjusts accordingly. You do not need a special crossover cable to connect it directly to another device or switch.

Q: Is the LAN8720 module suitable for industrial use?

A: Absolutely. The module is rated for an operating temperature range of -40°C to +85°C, making it suitable for demanding industrial environments where standard consumer electronics would fail. Its low-power design also makes it ideal for always-on or embedded server deployments.

Q: How many modules do I receive per order?

A: You can choose your quantity at checkout: 1 pc, 5 pcs, or 10 pcs. This flexibility makes the LAN8720 module a cost-effective choice whether you're prototyping a single unit or building a small production run.
