BM160 Class 2 Multimedia Module
CSR,
• Weight: 0.8g
Product Description:
The BM160 is base on BlueCore5-Multimedia ROM QFN chipset from
leading Bluetooth chipset supplier Cambridge Silicon Radio.
System Architecture
BM160 interfaces a Bluetooth radio, baseband, DSP, high-quality audio
codec, SMPS, LDOs, a battery charger and external EEPROM memory.
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 battery codec) and 5-band EQ.
The module and device firmware is fully compliant with the Bluetooth
specification v2.1+EDR
Applications:
• Hands-free Car Kit
• Stereo Headset
• AV Headphones
• Echo Cancellation
• High Performance Mono Headsets
• Wireless Speakers
