onsemi T30HM1TS2500 Ethernet Controller
10BASE-T1S Ethernet Controller, Treo Platform, MAC-PHY with SPI Interface
The T30HM1TS2500 is an IEEE 802.3cg compliant Ethernet Transceiver with integrated Media Access Controller (MAC-PHY). It is capable of communication with multiple nodes connected to a shared medium (UTP) at 10 Mbps. The T30HM1TS2500 consists of CSMA/CD MAC and PHY with Physical Layer Collision Avoidance (PLCA). The T30HM1TS2500 uses SPI (with a clock up to 25 MHz) as an interface to higher layers. This device is AEC-Q100 qualified for automotive applications.
