Synopsys, Inc. (NASDAQ:
SNPS), a world leader in software and IP for semiconductor design, verification
and manufacturing, today announced the addition of the new DesignWare® USB
2.0 picoPHY IP to its USB 2.0 PHY IP product line that has been successfully
deployed in more than 300 customer designs, and in more than 50 different process
technologies ranging from 180-nanometer (nm) to 32-nm. Targeted at mobile and
high-volume consumer applications such as feature-rich smartphones, mobile internet
devices and netbooks, the DesignWare USB 2.0 picoPHY supports advanced 28-nm
processes in a 1.8V architecture, is 30 percent 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 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.
"Delivery of USB IP solutions from providers like Synopsys helps system
designers benefit from the latest functionality offered by USB technology,"
said Jeff Ravencraft, president and chairman of the USB Implementers Forum.
"With the prevalence of USB on mobile devices, IP solutions like 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."
"For nearly a decade, designers have successfully incorporated Synopsys'
high-quality DesignWare USB 2.0 PHY IP into their SoCs which they have shipped
in hundreds of millions of units," said John Koeter, vice president of
marketing of the Solutions Group at Synopsys. "The addition of the new
DesignWare USB 2.0 picoPHY IP to this already widely adopted product line provides
designers with a competitive edge through our continued innovation and support
for the latest processes and specifications."
