1.General Description and Specification

1.1 General Description

This product is a SMT Bluetooth Module used BlueCore CSR8670 BGA. Its a

perfect consumer audio solution for wireless applications, such as wireless soundbars,

wireless stereo speakers and headphones. Its slim and light so the designers can have

better flexibilities for the product size.

This module complies with Bluetoothٛspecification version 4.1. It can support

HSP,HFP,A2DP,AVRCP,PBAP,MAP,SPP profiles.

Radio includes integrated balun,

and integrates an ultra-low-power DSP and application processor with embedded flash

memory, a high-performance stereo codec, a power management subsystem, LED and

LCD drivers inputs in a SOC IC. The dual-core architecture with flash memory enables

manufactures to easily differentiate their products with new features without extending

development cycles.
