Intersil Corp., Irvine, Calif., today released a reference targeted at both home wireless gateways and access points in small offices, and features the first product offering from Intersil's new PRISM/home product line.
The reference design integrates all electronic components on a single board that measures approximately 2.5-by-3.75 inches. At the heart of the design are Intersil's PRISM II chips, including a new ARM-based Access Point Controller engine that performs the IEEE 802.11 Medium Access Controller (MAC), wired Ethernet MAC and gateway control functions. This eliminates the need for a separate gateway host microprocessor and simplifies the overall design, said Larry Ciaccia, vice president and general manager of PRISM wireless products at Intersil.
"This single-board reference design requires no additional add-in cards and its small size, high performance and low cost make it ideal as a wireless gateway to the Internet in homes or to the LAN in offices," Ciaccia said.
The PRISM/home AP Reference Design delivers 11 megabits per second (fully compliant with the IEEE 802.11b standard) and will be available with Wi-Fi certification from the Wireless Ethernet Compatibility Alliance (WECA) to ensure multi-vendor interoperability.
"Consumers around the world, particularly in places such as Japan, are increasingly accessing the Internet through residential gateways with broadband cable, ISDN or DSL connections," Ciaccia added. "Our new reference design will make it easier for OEMs to quickly satisfy this."
For customers who use the reference design with minimum changes, system design effort and time-to-market can be reduced by up to 80%, Ciaccia, said.
