Serial Port Module
1.0 General Description
The National Semiconductor LMX9838 Bluetooth Serial Port
module is a fully integrated Bluetooth 2.0 baseband controller,
2.4 GHz radio, crystal, antenna, LDO and discreets; com-
bined to form a complete small form factor (10 mm x 17 mm
x 2.0 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 LMX9838 is qualified as a Bluetooth endproduct, ready to
be used in the end application without additional testing and
license cost.
Based on National鈥檚 CompactRISC
廬
16-bit processor archi-
tecture and Digital Smart Radio technology, the LMX9838 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. 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 module is lead free and RoHS (Restriction of Hazardous
Substances) compliant. For more information on those quality
standards, please visit our green compliance website at
