How Does The Two-Wire ETH Click Board™ Work?
The Two-Wire ETH Click Board™ is based on the LAN8651, a compact, low-power, single-port 10BASE-T1S MAC-PHY Ethernet Controller with SPI from Microchip designed according to the IEEE Std 802.3cg-2019 and OPEN Alliance TC-6 10BASE-T1x MAC-PHY Serial Interface specifications. The LAN8651 combines a Media Access Controller (MAC) and PHY to enable low-cost MCUs to access 10BASE-T1S networks. It provides 10Mbit/s half-duplex transmit and receive capability over a single balanced pair of conductors connected to the onboard Ethernet terminal. The LAN8651 also complies with industrial EMC and EMI requirements, making it suitable for functional safety-related applications.
The integrated PHY of the LAN8651 allows for creating both multidrop and point-to-point network topologies, with up to at least 15m in length for a point-to-point network. The multidrop mode supports up to at least 8 PHYs connected to a common mixing segment of up to at least 25m in length. The ability to connect multiple PHYs to a common mixing segment reduces weight and implementation costs by reducing cabling and switch ports.
The LAN8651 integrated Ethernet MAC communicates with the host MCU through a standard Serial Peripheral Interface (SPI) supporting high clock speed up to 25MHz. Ethernet data transfer as well as command/status commands are performed over a single, serial interface. The serial interface allows of both transmit and receive packets simultaneously between the station controller and the LAN8651. Packets are typically stored within the LAN8651 before being forwarded to either the station MCU or the network. Alternatively, packets may be transferred in a cut-through mode, with minimal buffering, for applications needing reduced latency. In addition to the Ethernet terminal mentioned above, this board has two jumper settings for enabling 100Ω edge termination at the ends of a 10BASE-T1S segment. Both jumpers must be populated to allow edge termination.
Alongside SPI pins of the mikroBUS™ socket, this Click board™ also has a multi-function interrupt IRQ pin, GPIO interface on IO0 and IOX, and a general reset signal to reset the LAN8651. In addition to hardware reset, the possibility of a Power-On reset is also provided, achieved using the MIC2790. It also has a Wake-Up function, accomplished by the WI pin or the WI button, and an additional INH indicator set to a low logic state in Sleep mode or a high state when PHY determines a qualified Wake-Up condition. To make identification as simple as possible, this board also has an additional EEPROM memory, the AT24MAC402, accessible via the I2C interface.
The Two-Wire ETH Click Board™ can only be operated with a 3.3V logic voltage level. The board must perform appropriate logic voltage level conversion before using MCUs with different logic levels. However, the Click board™ comes equipped with a library containing functions and an example code that can be used as a reference for further development.

What is 10BASE-T1S?
10BASE-T1S is a type of Ethernet networking technology that allows for data communication at a speed of 10 megabits per second (Mbps) over a single twisted pair cable. It is designed for use in automotive and industrial environments, where traditional Ethernet cabling is not practical or suitable. The "10" in the name refers to the maximum data transfer rate of 10 Mbps, while "BASE" indicates that the technology uses baseband signaling, where the entire bandwidth of the cable is used for a single signal. "T1" refers to the use of twisted pair cable, while "S" stands for "single", meaning that only one twisted pair is used for transmission and reception. 10BASE-T1S is a newer variant of the 10BASE-T1 technology, with the added benefit of being able to operate over longer distances and with better noise immunity. It is also more power-efficient than other Ethernet technologies, making it well-suited for use in battery-powered devices.
