Arasan Chip Systems, the leading provider of IP for Mobile and Automobile SOC’s, presents its latest eUSB2 IP. eUSB2 is a new generation specification proposed by USB Association that extends USB 2.0 specification and uses 1.2V/1.0V as the interface operating voltage. Unlike traditional USB, which uses external connectors and cables, eUSB is optimized for direct chip-to-chip communication within a device.
eUSB2 can support USB high-speed, full-speed, and low-speed operation, as well as the USB 2.0 L1/L2 link power management requirements. In addition, eUSB2 requires no change to the existing USB 2.0 software programming model. 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.
