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 con-
troller 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 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 Ap-
plication 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. Moreover,
the LMX9830 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.
Based on National's CompactRISC® 16-bit processor archi-
tecture and Digital Smart Radio technology, the LMX9830 is
optimized to handle the data and link management process-
ing 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 supports up to
7 active Bluetooth data links and one active SCO link.
The on-chip Patch RAM provided for lowest cost and risk, al-
lows the flexibility of firmware upgrade.
The LMX9830 module is lead free and RoHS (Restriction of
Hazardous Substances) compliant. For more information on
those quality standards, please visit our green compliance
