Synopsys introduced DesignWare USB 2.0 picoPHY IP. The IP supports advanced 28nm processes in a 1.8V architecture, is 30% smaller than the previous USB 2.0 PHY generation, and offers reduced pin count and low standby power consumption. The DesignWare USB 2.0 picoPHY is ideal for mobile and high-volume consumer applications such as feature-rich smartphones, mobile internet devices, and netbooks. The DesignWare USB 2.0 picoPHY IP is expected to be available to early adopters starting in Q4 2009 for 28-nm processes, with a roadmap for 40- and 32-nm.
Synopsys’ new DesignWare USB 2.0 picoPHY IP will enable designers to quickly incorporate this technology into their SoCs designs and bring new USB-enabled products to the market quickly. The DesignWare USB 2.0 picoPHY IP is the first PHY IP to support the new Battery Charging version 1.1 and USB On-the-Go (OTG) version 2.0 specifications from the USB Implementer’s Forum (USB-IF). The Battery Charging v 1.1 specification allows mobile devices to draw up to 1.8 A of current when connected to a wall charger. The Battery Charging specification enables portable devices to distinguish among various power sources, such as a wall charger, standard host port and USB charging port, and selects the most efficient method to charge the device.
By supporting the USB OTG version 2.0 specification, the DesignWare USB 2.0 picoPHY incorporates the new Attached Detection Protocol (ADP) feature, which improves the power efficiency of portable devices that communicate directly to USB peripherals without the need for a PC Host. In addition the DesignWare USB 2.0 picoPHY supports advanced power management features, such as power supply gating and support for ultra-low standby current to help designers lower the leakage power of mobile system-on-chips (SoCs) while maintaining the integrity of the USB 2.0 connection.
