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.
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.
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.
