Bluetron™ Application Specific Module
BTR50x

The Bluetron™ BTR50x module from AvantWave is a complete Bluetooth® solution for fast implementation, cutting your time-to-market. It is a short-range, compact and cost effective radio/baseband module that can be implemented in any kind of electronic devices, such as hands-free car kit, stereo headset/headphone, home audio system, etc.

In standard configuration the module includes a baseband processor with on board Flash memory, a radio front-end, supporting circuitry, together with some higher-level software protocols and applications such as HSP, HFP, A2DP, AVRCP are resided in the Flash.

The Bluetron™ BTR50x module module is a power class 2 Bluetooth® device, and is in compliance with version 2.1 +EDR of the Bluetooth® specification. It is supplied with Bluetron™ protocol stack firmware which runs on the internal microprocessor. Bluetron™ BTR50x module module is built on CSR BC05 Multimedia External core with Flash memory for firmware and application software storage.

Configuration

The BTR50x is based on the scalable Bluetron™ architecture. This configuration allows embedded stand-alone Bluetooth® applications where your target application is embedded within the module, in addition to traditional host-based applications. This possibility is especially useful in portable type applications like car multimedia system, home audio system, etc. The variety of external interfaces also makes the BTR50x ideally suited for various applications in stereo headset/headphone, high-end audio systems.

Antenna Interface

50Ω Bluetooth® ISM Band antenna (2.4-2.5 GHz)


Communication Interface

Communication is carried out using a wide range of external interfaces like high-speed UART, SPI, USB (Universal Serial Bus), PCM and PIO.


Software

The standard firmware includes Bluetooth® protocol layers up to the HCI-layer or RFCOMM-layer. In addition, a variety of Bluetooth® stacks for host- and embedded applications with different configurations could be offered.
