LMX9820 Bluetooth™ Serial Port Module June 2004 LMX9820 Bluetooth™ Serial Port Module The firmware supplied within this device offers a plete Bluetooth (v1.1) stack including profiles and mand The National Semiconductor® LMX9820 Bluetooth™ Serial interface. This firmware Features point-to-point and point Port module is a highly integrated radio, baseband control- to-multipoint link management supporting data rates up to ler and memory device implemented on an LTCC (Low the theoretical maximum over RFm of 704 kbps. The Temperature Co-fired Ceramic) substrate. All hardware internal memory supports up to three active Bluetooth and firmware is included to provide a plete solution links. from antenna through the plete lower and upper layers of the Bluetooth stack, up to the application including the 1.1 APPLICATIONS Generic Access Profile (GAP), the Service Discovery Application Profile (SDAP), and the Serial Port Profile (SPP). - Personal Digital Assistants The module includes a configurable service database to - POS Terminals fulfil service requests for additional profiles on the host. The LMX9820 Features a small form factor (10.1 x 14.0 x - Data Logging Systems 1.9 mm) design; thus, solving many of the challenges associated with system integration. Moreover, the LMX9820 is pre-qualified as a Bluetooth Integrated ponent. Conformance testing through the Bluetooth qualification program enables a short time to market after system integration by insuring a high probability of pliance and interoperability. Based on National’s pact RISC ™ 16-bit processor architecture and Digital Smart Radio technology, the LMX9820 is optimized to handle the data and link management processing requirements of a Bluetooth node. 1.0 General Description 2.0 Functional Block Diagram LINK MGMNT PROCESSOR (LMP) FIRMWARE (INCLUDES PROFILES AND MAND INTERFACE) UART UART_RX UART_TX UART_RTS# UART_CTS# IOVCC TX_SWITCH_P ENV0 ENV1 LSTAT_0 LSTAT_1 HOST_WU RESET_B#...
