LMX9838 Bluetooth Serial Port Module September 2007 LMX9838 Bluetooth® 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; bined to form a plete small form factor (10 mm x 17 mm x 2.0 mm) Bluetooth node. All hardware and firmware is included to provide a plete solution from antenna through the plete lower and upper layers of the Bluetooth stack, up to the application including the Generic Access Profile (GAP), the Service Discovery Application 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’s pact RISC® 16-bit processor architecture and Digital Smart Radio technology, the LMX9838 is optimized to handle the data and link management processing requirements of a Bluetooth node. The firmware supplied in the on-chip ROM memory offers a plete Bluetooth (v2.0) stack including profiles and mand interface. This firmware Features point-to-point and point-to-multipoint link management supporting data rates up to the theoretical maximum over RFm 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, allows the flexibility of firmware upgrade. The module is lead free and Ro HS (Restriction of Hazardous Substances) pliant.
