Ethernet Controller

ASIC proven high-performance, feature-rich network interface solution designed to deliver reliable, low-latency Ethernet connectivity

The Ethernet Controller is an ASIC proven high-performance, feature-rich network interface solution designed to deliver reliable, low-latency Ethernet connectivity across a broad range of embedded and enterprise applications. Comcores offers controllers ranging from 10M to 800G enabling seamless integration into systems requiring Ethernet connectivity.

Designed for scalability, the controller is available with single or multi-port configurations and is fully compliant with IEEE Ethernet standards, ensuring interoperability and long-term product viability.

Optimized for low power and high throughput, the controller supports advanced networking features including IEEE 802.1AS time synchronization, VLAN tagging, and optional MACsec encryption. With flexible host interface options (e.g., PCIe, RGMII, SPI), integrated DMA engines, and support for hardware timestamping, the Ethernet controller ensures efficient packet processing. Precise timing for time-sensitive applications such as TSN, industrial automation, automotive Ethernet, and audio/video streaming is supported as well.
