Features ■ ■ _äìÉqìåÉë∆=olj=nck _äìÉqìåÉë=olj=píÉêÉç=eÉ~ÇëÉí=pçäìíáçå Single-chip Bluetooth® v2.1 + EDR System Production Information BC57F687A05 Issue 3 ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ Cost-effective single-chip solution for stereo headset and wireless speaker applications A2DP1.2 and AVRCP1.0 profiles enabled with SBC encoder for streaming audio over Bluetooth and for remote control functionality MP3 decoder for improved audio quality and reduced power consumption (MP3 decode functionality requires an appropriate licence from Thomson, see Section 17.1) Configurable A2DP 5-band EQ High-quality audio 95dB SNR on DAC playback 64MIPS Kalimba DSP coprocessor FastStream, CSR’s low-latency codec for video and gaming applications HFP 1.5 (includes 3-way calling) and HSP 1.0 support cVc support for echo and noise reduction Low-power consumption: over 10 hours of audio playback from a 180mAh battery Fully qualified Bluetooth v2.1 + EDR specification system with support for secure simple pairing Best-in-class Bluetooth radio with 8dBm transmit power and -92dBm receive sensitivity 2 integrated linear regulators with 1.5V output from 1.7V to 1.95V input Integrated switch-mode regulator Integrated lithium battery charger 68-lead 8 x 8 x 0.9mm, 0.4mm pitch QFN package Green (RoHS compliant and no antimony or halogenated flame retardants) BlueTunes ROM stereo headset solution development kit available, includes example design. Order code BTN-003-1A ■ ■ _äìÉqìåÉë=olj=nck Data Sheet General Description Based on _äìÉ`çêÉ∆RJjìäíáãÉÇá~=olj=nck, the _äìÉqìåÉë=olj=nck integrates a Bluetooth radio, baseband, DSP, high-quality audio codec, SMPS, LDO and a battery charger for minimal BOM, component count and PCB area. BlueTunes ROM QFN uses advanced DSP features for the latest stereo enhancements and to improve audio quality, including SBC and MP3 decoder, support for FastStream (low-latency codec) and 5‑band EQ. XTAL RAM I2C EEPROM Applications Stereo headset solution with support for echo and noise reduction Wireless stereo speakers BlueTunes ROM QFN includes as standard cVc dual and single microphone algorithms for echo and noise suppression. cVc dual-microphone algorithm can provide >30dB of noise suppression in both stationary and dynamic noise conditions such as; babble, road, music and competing voices. In addition an acoustic echo canceller is now integrated into the cVc dualmicrophone solution, further enhancing the far-end user experience. A cVc single-microphone provides full-duplex echo cancellation and a 10dB stationary noise suppressor. BlueTunes ROM QFN includes secure simple pairing, which greatly simplifies the pairing process, making it even easier to use a Bluetooth headset.
