The onsemi T30HM1TS2500 is a 10BASE-T1S Ethernet Controller designed to enable reliable multi-node communication over a single twisted pair. Based on the IEEE 802.3cg standard, the device integrates both the MAC and PHY into a compact solution, supporting 10 Mbps Ethernet communication while simplifying network architectures and reducing wiring complexity.
Engineered for automotive and industrial networking applications, the T30HM1TS2500 incorporates Physical Layer Collision Avoidance (PLCA) technology to provide deterministic communication performance across multidrop networks. An SPI interface enables seamless integration with host microcontrollers, while advanced power management features support low-power operation and flexible wake-up capabilities.
