LMX9820ADONGLE/NOPB

LMX9820ADONGLE/NOPB 1.0 General Description

The National Semiconductor LMX9820A Bluetooth SerialPort 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 andupper layers of the Bluetooth stack, up to the applicationsupport layers including the Generic Access Profile (GAP),the Service Discovery Application Profile (SDAP), and theSerial 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 smallform factor (10.1 x 14.1 x 2.0 mm) design, which solvesmany of the challenges associated with compact systemintegration. Moreover, the LMX9820A is pre-qualified as aBluetooth Integrated Component. Conformance testingthrough the Bluetooth qualification program enables a fasttime to market after system integration by ensuring a highdegree of compliance and interoperability.
