Taipei, Taiwan – June 16, 2026 – Neousys Technology, a leader in rugged embedded systems, announces the PCIe-AE304bp, a wide-temperature, fanless 4-port Automotive Ethernet PCI Express card designed to accelerate ADAS and autonomous driving validation. Purpose-built for modern vehicle network architectures, PCIe-AE304bp brings direct 100/1000BASE-T1 connectivity into x86-based platforms, eliminating external media converters and delivering a simpler, more reliable in-vehicle Ethernet integration solution.
Simplified Integration for Rugged Operation
PCIe-AE304bp integrates Automotive Ethernet directly into the host system through a standard PCIe form factor, removing the need for external RJ45-to-T1 media converters. This reduces system complexity, minimizes cabling, and eliminates additional connection points that are often vulnerable to vibration in automotive environments. The result is a more stable and deployment-ready test setup for both lab validation and in-vehicle applications.
Flexible 100/1000BASE-T1 Support
Based on Marvell 88Q2221 PHYs, PCIe-AE304bp supports software-configurable 100BASE-T1 and 1000BASE-T1 operation in compliance with IEEE 802.3bw and IEEE 802.3bp standards. Flexible master/slave configuration enables interoperability across a wide range of Automotive Ethernet endpoints, including LiDAR, radar, sensor fusion modules, and ECUs. This BASE-T1 implementation supports the ongoing transition toward Ethernet-centric vehicle architectures, enabling high-bandwidth data transmission, software updates, diagnostics, and scalable data logging across distributed in-vehicle networks.
Fanless Wide-Temperature Operation
Engineered for harsh automotive environments, PCIe-AE304bp features a fanless thermal design with a -25°C to 70°C operating temperature range, ensuring stable and deterministic performance in real-world deployment conditions. Its ruggedized architecture is designed to withstand continuous vibration, thermal cycling, and extended operational workloads, making it suitable for engineering development, system validation, and production test applications.
With a half-length, single-slot PCIe design and support for multi-card expansion, PCIe-AE304bp provides a scalable Automotive Ethernet platform for next-generation ADAS and autonomous driving test systems.
