Arasan’s eUSB2 IP is a complete controller + PHY solution that brings USB 2.0 compatibility into low-voltage, chip-to-chip environments (≈1.0 V–1.2 V) for advanced SoCs. It supports USB high-speed, full-speed, and low-speed modes and reuses USB 2.0 software programming models with no changes required. eUSB2 also uses the same two data line configurations, eD+ and eD- as USB2 D+ and D-. Vbus and power delivery are not impacted by eUSB2.
While traditional eUSB2 meets basic connectivity needs at 480 Mbps, modern SoCs and peripherals demand significantly higher throughput. eUSB2-V2.0 bridges this gap by delivering up to 10× performance improvement, along with better power efficiency and EMI control — without changing the fundamental USB 2.0 software ecosystem.
Arasan eUSB2V2.0 is the current, enhanced implementation with support for flexible data rate configurations and optimized link performance, tailored for advanced SoC designs.
