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.
