General Description

BlueCore

BC6145™ QFN is a low-cost fully-featured

ROM IC solution for Bluetooth mono headsets with

extremely low power consumption. The BC6145 QFN

ensures increased speech clarity and improves

intelligibility through spectral enhancement, with the

bidirectional noise reduction

Hear and Be Heard

feature.

BC6145 QFN reduces the number of external

components required, minimising production costs. It

includes a Bluetooth radio, baseband, Kalimba DSP,

DAC/ADC, switch-mode power supply and battery

charger in a QFN package for low-cost designs.

The Kalimba DSP coprocessor supports enhanced

audio applications. A2DP streaming enables music

playback on a mono headset.

Applications

■

BC6145 QFN DSP mono headset solution

■

Low-cost speakerphones and car-kits

BC6145 QFN includes CVC single-microphone echo

and noise reduction, which reduces headset echo

enabling the headset-user to be heard more clearly. A

low-power wind noise reduction feature improves

intelligibility in windy environments.

BC6145 QFN supports secure simple pairing which

simplifies the pairing process and makes it easier to

use a Bluetooth headset.

The device includes auto-calibration and BIST

routines to simplify development, type approval and

production test.
