LMX9820

Bluetooth™ Serial Port Module

The firmware supplied within this device offers a complete

Bluetooth (v1.1) stack including profiles and command

interface. This firmware features point-to-point and point-

to-multipoint link management supporting data rates up to

the theoretical maximum over RFComm of 704 kbps. The

internal memory supports up to three active Bluetooth

links.

1.0 General Description

The National Semiconductor LMX9820 Bluetooth™ Serial

Port module is a highly integrated radio, baseband control-

ler and memory device implemented on an LTCC (Low

Temperature Co-fired Ceramic) substrate. 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), the Service Discovery Appli-

cation Profile (SDAP), and the Serial Port Profile (SPP).

The module includes a configurable service database to

fulfil service requests for additional profiles on the host.

The LMX9820 features a small form factor (10.1 x 14.0 x

1.9 mm) design; thus, solving many of the challenges

associated with system integration. Moreover, the

LMX9820 is pre-qualified as a Bluetooth Integrated Com-

ponent. Conformance testing through the Bluetooth qualifi-

cation program enables a short time to market after system

integration by insuring a high probability of compliance and

interoperability.

1.1 APPLICATIONS

■ Personal Digital Assistants

■ POS Terminals

■ Data Logging Systems

™

Based on National’s CompactRISC 16-bit processor

architecture and Digital Smart Radio technology, the

LMX9820 is optimized to handle the data and link manage-

ment processing requirements of a Bluetooth node.
