LMX9830
Bluetooth™ Serial Port Module
1.0 General Description
The National Semiconductor LMX9830 Bluetooth Serial
Port module is a highly integrated Bluetooth 2.0 baseband
controller and 2.4 GHz radio, combined to form a complete
small form factor (6.1 mm x 9.1 mm x 1.2 mm) Bluetooth
node.
All hardware and firmware is included to provide a com-
plete solution from antenna through the complete lower
and upper layers of the Bluetooth stack, up to the applica-
tion including the Generic Access Profile (GAP), the Ser-
vice Discovery Application Profile (SDAP), and the Serial
Port Profile (SPP). The module includes a configurable ser-
vice database to fulfil service requests for additional pro-
files on the host. Moreover, the LMX9830 is pre-qualified
as a Bluetooth Integrated Component. Conformance test-
ing through the Bluetooth qualification program enables a
short time to market after system integration by insuring a
high probability of compliance and interoperability.
Based on National’s CompactRISC^™ 16-bit processor
architecture and Digital Smart Radio technology, the
LMX9830 is optimized to handle the data and link manage-
ment processing requirements of a Bluetooth node.
The firmware supplied in the on-chip ROM memory offers a
complete Bluetooth (v2.0) stack including profiles and com-
mand 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
(Best in Class in the industry). The internal memory sup-
ports up to 7 active Bluetooth data links and one active
SCO link.
The on-chip Patch RAM provided for lowest cost and risk,
allows the flexibility of firmware upgrade.
The LMX9830 module is lead free and RoHS (Restriction
of Hazardous Substances) compliant. For more information

ance website at http://www.national.com/quality/green/
