It is designed using advanced CMOS technology to provide MII and RMII interfaces for easy attachment to 10/100 media access controllers (MAC).
The ST802RT1x supports the 100BaseTX of IEEE802.
3u and 10Base-T of IEEE802.
3i and 100Base FX of IEEE 802.
3u (B version only).
The ST802RT1x supports both half-duplex and full-duplex operation at 10 and 100 Mbps operation.
Its operating mode can be set using auto-negotiation, parallel detection or manual control.
It allows for the support of autonegotiation functions for speed and duplex detection.
The automatic MDI / MDIX feature compensates for the use of a crossover cable.
With auto MDIX, the ST802RT1x automatically detects what is on the other end of the network cable and switches the TX & RX pin functionality accordingly.
