STMicroelectronics STE100P 10/100 Fast Ethernet Transceiver Datasheet
The STE100P, also referred to as STEPHY1, is a high-performance Fast Ethernet physical layer interface designed for 10BASE-T and 100BASE-TX applications. It utilizes advanced CMOS technology to provide a Media Independent Interface (MII) for easy attachment to Media Access Controllers (MAC) and a physical media interface compliant with IEEE 802.3 standards. The device supports both half-duplex and full-duplex operation at 10 and 100 Mbps, with operating modes configurable via auto-negotiation, parallel detection, or manual control.
