Ethernet End Station
One End Station family, every speed from 10M to 2.5G — MAC, timing, security and TSN features built in
Overview
The Comcores End Station is a silicon-proven hardware + software subsystem that turns any device into a deterministic Ethernet endpoint — MAC, time synchronisation, protocol gateway and security in one licensable IP core, for ASIC and FPGA.
One family covers everything from a 10M single-pair sensor node to a 2.5G full-TSN controller, with the same deliverables, the same support and the same integration model at every speed.
Complete endpoint subsystem
MAC, Time-of-Day, IEEE 1722 gateway, MACsec and software stack — not a bare MAC.
Silicon-proven, technology independent
SystemVerilog RTL or encrypted netlist, validated in ASIC and FPGA. Functional Safety Ready — ISO 26262 / ASIL aligned.
One family, every speed
10M · 100M · 10–100M · 10M–1000M · 10M–2.5G — pick the speed, keep the architecture.
Software included
802.1AS stack, FreeRTOS / Zephyr / Linux drivers and a complete demonstration system.
Wide Range – One family. 10 Mb/s to 2.5 Gb/s
One architecture, four members — each covering a different slice of the same speed range. The smallest is a single-pair 10M endpoint; the largest reaches deterministic 2.5G with full TSN.

Endpoint in detail
A comprehensive, silicon-proven hardware and software solution for the Ethernet edge node.
The End Station Controller contains a Media Access Controller (MAC) at 10M, a Time-of-Day (TOD) system, and an optional MACsec protection block. It interfaces with nearly any microcontroller or embedded processor over SPI or an AXI Memory-Mapped host interface — with cut-through packet handling as configured.
It supports half- and full-duplex operation over standard MII/RMII, implements IEEE 802.1AS with the 802.1ASds amendment for half-duplex, and ships with device drivers, an 802.1AS stack and a complete FreeRTOS-based demonstration system. Delivered as technology-independent SystemVerilog RTL or encrypted netlist for ASIC and FPGA.
Key Capabilities
A comprehensive hardware and software TSN capable solution for automotive, aerospace and industrial applications.
The 10M/100M/1G/2.5G Ethernet TSN End Station Controller implements Timing & Synchronisation (802.1AS), Traffic Shaping (802.1Qbv TAS, 802.1Qav CBS, 802.1Qat ATS), Frame Preemption (802.1Qbu), Frame Replication & Elimination (802.1CB), Stream Filtering & Policing (802.1Qci), and optional MACsec (802.1AE) — up to 8 traffic classes, each with a dedicated queue.
Standard GMII/RGMII/SGMII and MDIO PHY interfaces; a 32-bit AXI4-Lite configuration bus and a multichannel DMA controller on a memory-mapped AXI4 master port. The IEEE 1722 gateway is available via fused 10M-class controllers. Ships with OS drivers, an 802.1AS stack and a Linux demonstration system.

Omni500 – Configurable evaluation and prototyping platform
The Omni500 is a configurable evaluation and prototyping platform for deterministic Ethernet systems from 10 Mb/s to 1 Gb/s. It combines TSN networking, multi-speed Ethernet interfaces, and field buses into one compact platform for validation, development, and system integration.
Omni500 is built on combining an AMD Artix UltraScale+ FPGA, Linux-capable control processor, and a comprehensive set of interfaces.
Built for engineers who need deterministic results. The platform handles all real-time packet processing and timestamping in hardware, while the Linux control layer provides the flexibility of a full software stack — Web GUI, REST API, and SDK included.
