National Semiconductor's Bluetooth Radio Achieves v1.1 Certification from Bluetooth SIG

Certification Allows Customers to Implement Bluetooth-enabled Products Using National's 0.25 Micron CMOS Technology and Display the Bluetooth Trademark

Dec 10, 2001

December 10, 2001 - Today at the Bluetooth™ Developers Conference, National Semiconductor Corporation (NYSE:NSM) announced that its second generation Bluetooth radio, the LMX5250, has achieved v1.1 certification from the Bluetooth special interest group (SIG) Inc.  This certification means that National's radio has passed the extensive testing required by the Bluetooth SIG. For National's customers, this ensures low development risk as well as reduced time-to-market when certifying their products as Bluetooth-enabled.

"Gaining Bluetooth Certification for the LMX5250 is a key milestone en route to National supplying the market with its compact, low power, cost effective Bluetooth solutions," said Jim Benefer, Bluetooth product marketing manager for National Semiconductor. "In addition, National has also qualified its San Diego wireless design center as a Bluetooth Qualification Test Facility (BQTF), which will provide our customers with the added advantages of immediate Bluetooth radio testing by staff familiar with National's radio, which can equate to faster time to market."

A BQTF is a facility that has been authorized by the Bluetooth SIG to conduct Bluetooth testing. The award of Bluetooth Certification is subject to a Bluetooth Qualification Body's (BQB) approval.

About the LMX5250
The LMX5250 is a highly-integrated 2.4GHz transceiver that utilizes an advanced radio architecture to support optimized Bluetooth communication, with very few additional components required.  Key features include power management and 2V supply voltage for very low power consumption, internal radio calibration circuits for minimum production test time, good receive sensitivity for increased range, and serial interface for control and data communication.

The LMX5250 supports Class 2 and 3 transmit power level on-chip, making it well-suited for applications such as cellular phones, PDAs, digital cameras and headsets. The transmit section utilizes National's advanced PLL expertise to offer very low frequency jitter, key to ensuring better data throughput. Since its architecture exhibits very little spurious noise, it is also very well suited to Class 1 transmit applications, such as PCs and Peripherals. Class 1 support requires an external Power Amplifier.

The LMX5250 can be used in combination with the LMX5100 baseband/link manager chip to form a complete Bluetooth node. The LMX5100 is a highly-flexible RISC-based Bluetooth processor that includes a dedicated Bluetooth 'core' to significantly reduce the processing required to implement a Bluetooth node.  The LMX5100 has sufficient on-chip Flash memory and SRAM to permit the implementation of a full functionality Bluetooth node with no external memory.

Both products are currently being sampled to major customers.  More information on the chipset is available at BLUETOOTH® Wireless Technology.
