LMX9820A Datasheet | National Semiconductor

.. APRIL 2005 Revision 1.0 LMX9820A Bluetooth Serial Port Module LMX9820A Bluetooth® Serial Port Module 1.0 General Description The National Semiconductor LMX9820A Bluetooth Serial Port module is a highly integrated radio, baseband controller, and memory device implemented on an FR4 substrate. All hardware and firmware is included to provide a plete solution from antenna from the plete lower and upper layers of the Bluetooth stack, up to the application support layers 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 fulfill service requests for additional profiles on the host. The LMX9820A Features a small form factor (10.1 x 14.1 x 2.0 mm) design, which solves many of the challenges associated with pact system integration. Moreover, the LMX9820A is pre-qualified as a Bluetooth Integrated ponent. Conformance testing through the Bluetooth qualification program enables a fast time to market after system integration by ensuring a high degree of pliance and interoperability. Based on National’s pact RISC™ 16-bit processor architecture and Digital Smart Radio technology, the LMX9820A is optimized to handle the data and link management processing requirements of a Bluetooth node. The firmware supplied with this device offers a plete Bluetooth (v1.1) stack including profiles and mand interface. This firmware Features point-to-point and pointto-multipoint link management supporting data rates up to the theoretical maximum over RFm of 704 kbps. The internal memory supports up to three active Bluetooth data links and one active SCO link. 1.1 APPLICATIONS - Personal Digital Assistants - POS Terminals - Data Logging Systems - Audio Gateway applications 2.0 Functional Block Diagram LINK MGMNT PROCESSOR (LMP) FIRMWARE (INCLUDES PROFILES AND MAND INTERFACE) UART UART_RX UART_TX UART_RTS#...
