Features 1 Applications -T hu rs General Description fo r - _SNQM=nck is a product from CSR's Connectivity Centre. It is a low-cost fully featured ROM IC solution for mono headsets with extremely low power consumption. BC6140 QFN is the first CSR solution to include improved packet/bit error correction, a CSR solution to reduce noise and interference at the nearend enabling the headset-user to enjoy superior audio quality. Pr ep ar ed BC6140 QFN reduces the number of external components required ensuring production costs are minimised. It includes a Bluetooth radio, baseband, Kalimba DSP, DAC/ADC, switch-mode power supply and battery charger in a compact QFN package for low-cost designs. BC6140 QFN contains the Kalimba DSP coprocessor for supporting enhanced audio applications. XTAL RF IN RF OUT Speaker 1 Microphone 1 CS-124228-TOP2 Low-cost mono DSP headset BC6140 QFN includes state-of-the-art CVC singlemicrophone echo and noise reduction, which reduces headset echo allowing the headset-user to be heard more clearly. Advanced Multipoint enables HFP connection to 2 phones simultaneously, enhancing the use case for voice. BC6140 QFN supports Secure Simple Pairing which simplifies the pairing process and makes it easier to use a Bluetooth headset. The device incorporates auto-calibration and BIST routines to simplify development, type approval and production test. See CSR Glossary www.csrsupport.com.
