Microchip LAN8650B1T-E/LMX, Ethernet Transceiver, 100Mbps, Serial-SPI, 1.2 V, 24-Pin VQFN

The Microchip LAN8650 combines a Media Access Controller and an Ethernet PHY to enable low‑cost microcontrollers, including those without an onboard MAC, to access 10BASE‑T1S networks. The common standard Serial Peripheral Interface of the LAN8650 allows interfacing with nearly any microcontroller, so that the transfer of Ethernet packets and LAN8650 control/status commands are performed over a single, serial interface. SPI also requires only 4 pins, enabling a simpler hardware interface with fewer pins than MII or RMII.

Internal wall clock
Event generation and event capture synchronized to the wall clock
Phase adjuster for the wall clock to minimize microcontroller overhead
Packet timestamping
Half duplex point to point link segments up to at least 15m
