LMX9820A Bluetooth Serial Port Module

General Description
The National Semconductor LMX9820A Bluetooth Seria Port module is a hghly ntegrated radio, baseband controler, and memory devicemplemented on an FR4 substrate.
All hardware and firmware is incuded to provde a comete solution from antenna from the complete lower and upper layers of the Bluetooth stack, up to the application support layers including the Generic Access Profie (GAP), the Service Dscovery Application Profie (SDAP), and the Serial Port Profile (SPP). The module ncudes a configurable service database to fulfill service requests for additional profiles on the host.

ntegration. 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 interoperabty.

Based on Natona’s CompactRISC16-bit processor architecturegital Smart Rado technoogy, the
LMX9820A is optimzed to handle the data and link management processng requirements of a Bluetooth node.

The firmware supplied wth this device offers a complete Bluetooth (v1.1) stack incuding profiles and command nterface. This firmware features point-to-point and point-to-mutipoint link management supporting data rates up to the theoretical maximum over RFComm of 704 kbps.
