USB OTG cores meet low-pincount
interface specs
Mentor Graphics has successfully received certification of its UTMI + low pin interface (ULPI) support for the USB On-The-Go standard from the USB Implementers Forum.
Mentor Graphics has successfully received certification of its UTMI + low pin interface (ULPI) support for the Universal Serial Bus (USB) On-The-Go (OTG) standard from the USB Implementers Forum ULPI is a new interface standard for Hi-Speed USB IP systems designed to reduce the pin count of discrete Hi-Speed USB physical interfaces (PHYs)

Mentor Graphics and UMC deliver IC design kits
Mentor Graphics and UMC have joined to deliver a complete turnkey design flow, including the availability of IC design kits, for UMC's RF and analogue/mixed-signal process technologies.
Mentor supports TI DSPs and MCUs
Mentor Graphics is the first to reach agreement with Texas Instruments to deliver coverification processor support packages (PSPs) for Texas Instruments DSP and microcontroller solutions.
Most UTMI + PHY require between 40-60 pins from the USB IP controller but this solution reduces the number of pins down to 12 when using an off-chip or discrete PHY, resulting in a lower cost solution.
Mentor is a major contributor to the ULPI specification and supports the new ULPI interface standard with a wrapper for its Hi-Speed USB OTG cores.
This technology provides a highly cost-effective solution for the consumer electronics segment.

Mentor previously announced the successful certification of its Hi-Speed USB OTG controller IP by the USB Implementers Forum Compliance Workshop, part of an ongoing commitment to secure industry certification of its standards-based IP solutions.
Hi-speed USB systems require a parallel interface between the host controller and PHY in order to run the bus at 480Mbit/s, increasing complexity and pin count.
However, the certification of Mentor's ULPI support of USB OTG provides the customer with a risk-free low pin count interface when the IP controller and off-chip or discrete PHY are implemented.
Mentor's USB OTG controller combined with a reliable third-party PHY, such as SMSC's USB3300, currently the only PHY certified by the USB-IF, enables quick, proven integration and design reuse benefits, for a complete USB OTG solution.
The ULPI "wrapper" is a no-cost option provided with all of the Mentor Hi-Speed USB cores, and has been rigorously tested on real hardware for risk-free implementation.
"Building on the Hi-Speed On-The-Go certification achieved with Mentor in April, the certification of our USB3300 ULPI PHY with Mentor's USB OTG controller further demonstrates the robust interoperability of the combined ULPI solution", stated Steve Nelson, Vice President of Marketing, Connectivity Solutions at SMSC.
"The ULPI standard is gaining momentum across the board and its low pin count interface and low-risk implementation of Hi-Speed USB.
Many of our mutual customers are discovering the positive impact that our ULPI solution can make in bringing consumer electronics products rapidly into production".
"Mentor strives to provide complete, low-risk, certified standards-based IP solutions for key and emerging applications, and our relationship with SMSC helps accelerate the adoption of USB OTG", stated Michael Kaskowitz, Mentor Graphics IP Division General Manager and President of the VSI Alliance.
"Our customers are now able to develop innovative products that support the latest standards and manage competitive delivery schedules while minimising cost and risk by using our certified ULPI solution for USB On-The-Go designs".
