Serial Port Module
1.0 General Description
The National Semiconductor LMX9820A Bluetooth Serial
Port module is a highly integrated radio, baseband control-
ler, and memory device implemented on an FR4 substrate.
All hardware and firmware is included to provide a com-
plete solution from antenna from the complete lower and
upper layers of the Bluetooth stack, up to the application
support layers including the Generic Access Profile (GAP),
the Service Discovery Application Profile (SDAP), and the
Serial Port Profile (SPP). The module includes a config-
urable service database to fulfill service requests for addi-
tional profiles on the host. The LMX9820A features a small
form factor (10.1 x 14.1 x 2.0 mm) design, which solves
many of the challenges associated with compact system
integration. Moreover, the LMX9820A is pre-qualified as a
Bluetooth Integrated Component. Conformance testing
through the Bluetooth qualification program enables a fast
time to market after system integration by ensuring a high
degree of compliance and interoperability.
Based on National鈥檚 CompactRISC
鈩?/div>
16-bit processor
architecture and Digital Smart Radio technology, the
LMX9820A is optimized to handle the data and link man-
agement processing requirements of a Bluetooth node.
The firmware supplied with 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 data
links and one active SCO link.
