National Semiconductor’s New Simply Blue Module Supports Bluetooth 2.0, Enables High-Volume Bluetooth Cable Replacement and Voice Applications for Industrial, Scientific and Medical Markets

Company Demonstrates New Module, Voice/Audio Application and Handsfree Car Kit Using Bluetooth Technology at Wireless Connectivity (WiCon) World in London

May 24, 2005

May 24, 2005 - National Semiconductor Corporation (NYSE:NSM) today announced the newest member of its Simply Blue wireless family, a Bluetooth® module that simplifies RF board design.  The LMX9830 module eliminates cables in advanced data and voice applications for the industrial, scientific and medical (ISM) market as well as various handsfree devices.

National’s LMX9830 embeds a complete Bluetooth node including a CMOS radio transceiver that delivers the highest level of RF integration available, a protocol stack, application-specific profiles and a high-level command interpreter for communication with the host using the on-chip UART interface.

In addition to supporting numerous serial cable replacement applications, the LMX9830 supports embedded data and voice-oriented applications by enabling multiple connections with maximum data throughput and synchronous audio links (SCO).

“National’s Simply Blue concept is a superior solution for embedded Bluetooth cable replacement applications,” said Stephan Thaler, marketing director for National Semiconductor’s Device Connectivity Division.  “Because of their own time constraints, customers want a simple design and a flexible solution. National’s new Simply Blue module reduces RF board complexity, enabling customers to integrate the device directly onto their main board design.  This saves them time and money.”

Bluetooth wireless technology enables users to exchange information between a wide variety of computing and communications systems including mobile phones, PCs, printers, industrial and medical devices without connecting wires or cables.  The new features found in Bluetooth Specification Version 2.0 include fast connection setup, interlaced scanning and adaptive frequency hopping (AFH) for improved coexistence of Bluetooth with other 2.4 GHz devices.

The market for Bluetooth technology is growing.  In 2005, more than 200 million Bluetooth products will be manufactured and sold worldwide, according to recent estimates from market researcher In-Stat/MDR.

About the LMX9830
The LMX9830, in a 60-pin FBGA package measuring 9mm by 6mm by 1.2mm, combines a Bluetooth transceiver with a baseband processor.  The baseband processor features full Bluetooth 2.0 functionality and firmware and an enhanced command structure.  In addition, it combines on-chip, ROM-based memory with a seamless memory patch controller and flexible patch RAM.

All hardware and firmware is included to provide a complete solution from antenna through the complete lower and upper layers of the Bluetooth stack, up to the application including the Generic Access Profile (GAP), Service Discovery Application Profile (SDAP) and the Serial Port Profile (SPP). The module includes a configurable service database to fulfill requests for additional profiles on the host.

Availability
For samples of the LMX9830, please contact your local sales representative.  Production quantities will be available in the third quarter of 2005.
