NXP’s Wireless USB Controller eases Integration, saves Power

NXP Semiconductors’ Wireless USB device controller integrates directly into end systems at the board level, allowing a seamless replacement of wired USB in today’s systems.The ISP3582 is based on the Certified Wireless USB specification and boasts a small footprint and low power operation. NXP, the newly independent semiconductor company founded by Philips, expects the device to be popular with design engineers because it avoids the integration step of dongle and hub solutions.

The ISP3582 will be combined with Realtek’s highly integrated radio/baseband device, the RTU7011, in reference designs and modules, to deliver a CMOS solution capable of data transfers up to 480 Mbps.

To lower overall design risk and ease system validation efforts, the ISP3582 has undergone a high degree of interoperability testing with Intel’s Wireless USB Host solution.

Integration testing has had “great success,” according to Ganesh Prasad, general manager of UltraWideband networking operations at Intel. “NXP’s support on their Wireless USB device solution has been outstanding, and coupled with their knowledge of the USB market, it provides the company a bright future in this new wireless market.”

Key features of the ISP3582 include:

• ARM7 processor
• 32K bytes of ROM
• 96K bytes of configurable RAM for data and buffering
• 16 endpoints and flexible firmware structure
• 16-bit generic chip interface with DMA support
• 4-bit SDIO interface meets 1.1 specifications; extensions increase frequency to 50 Mhz
• Optimized direct-board connections, using less circuitry than an embedded wireless hub
• Same USB class driver structure for WUSB, eliminating need for software updates

“The ISP3582 represents the first step toward widespread adoption of Certified Wireless USB,” said Paul Marino, vice president and general manager of business line connectivity, NXP Semiconductors. “As a testament to our continued leadership in connectivity solutions, we now provide engineers with the freedom to choose from our wired USB families, migrate a system from wired to wireless with our compatible I/O or go directly to a Wireless USB design.”

The NXP ISP3582 CMOS Certified Wireless USB solution is sampling now in 112 pin TFBGA package. High-volume pricing for the ISP3582 is less than $5.65(USD). Evaluation kits, complete with Realtek physical layer support, are available for strategic customer engagements. Production shipments are expected in 2Q 2007.
