Overview

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.

What Makes Ethernet IP Truly Automotive-Grade

This blog examines what separates truly automotive-grade Ethernet IP from generic implementations across functional safety, time-sensitive networking, security, observability, lifecycle management, and the integration disciplines that only become visible once a program is deep into development.

How Time Sensitive Networking powers the Software Defined Vehicle

Software-Defined Vehicles (SDVs) are turning cars into distributed real-time computing platforms. Instead of dozens of standalone ECUs connected by a tangle of legacy field buses, we now see zonal controllers aggregating local I/O, centralized compute platforms running safety, mission critical software, and a service-oriented middleware layer stretching across the vehicle.

Automotive Ethernet with Comcores – Safety, Quality and ASIL certification of IP

In today’s automotive industry, safety and reliability are non-negotiable. With the increasing complexity of electronic systems in modern vehicles, ensuring compliance with ISO 26262 and Automotive Safety Integrity Level (ASIL) requirements is a demanding aspect of development. At Comcores, we embrace these challenges head-on, combining rigorous processes with a strong commitment to product quality.

What is TSN?

TSN, or Time-Sensitive Networking, is a technology based on the IEEE 802.1Q standard. It has evolved from the Ethernet technology currently used to carry all types of traffic, for which ethernet was not originally intended, such as multiple data flows with different timing requirements, commonly found in Audio Video Bridging (AVB), automotive and industrial automation applications.
