Bluetron™  Application Specific Module

BTR501

The Bluetron™ BTR50x module 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 3.0 +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.

*Rewritable Flash Memory: BTR501-8Mbit, BTR502-16Mbit, BTR503-32Mbit
