> The LAN8650/1 is designed to conform to the OPEN Alliance 10BASE‑T1x > MAC‑PHY Serial Interface specification, Version 1.1. The IEEE Clause 4 > MAC integration provides the low pin count standard SPI interface to any > microcontroller therefore providing Ethernet functionality without > requiring MAC integration within the microcontroller. The LAN8650/1 > operates as an SPI client supporting SCLK clock rates up to a maximum of > 25 MHz. This SPI interface supports the transfer of both data (Ethernet > frames) and control (register access). > > By default, the chunk data payload is 64 bytes in size. A smaller payload > data size of 32 bytes is also supported and may be configured in the > Chunk Payload Size (CPS) field of the Configuration 0 (OA_CONFIG0) > register. Changing the chunk payload size requires the LAN8650/1 be reset > and shall not be done during normal operation. > > The Ethernet Media Access Controller (MAC) module implements a 10 Mbps > half duplex Ethernet MAC, compatible with the IEEE 802.3 standard. > 10BASE-T1S physical layer transceiver integrated into the LAN8650/1.
