It is a single-chip radio and baseband IC for Bluetooth 2.4GHz systems. The integrated peripherals reduce the number of external components required, including no requirement for external codec, battery charger, SMPS, LDOs, balun or external program memory, ensuring minimum production costs. The battery charger architecture enables the CSR8610 BGA to independently operate from the charger supply, ensuring dependable operation for all battery conditions. 1-mic mono headset with NR / AEC Bluetooth hands-free car-kits Speakerphones The enhanced Kalimba DSP coprocessor with 80MIPS supports enhanced audio and DSP applications. The integrated audio codec supports 1 analogue input and 1 digital microphone (MEMS) interface and mono output, as well as a variety of audio standards. See CSR Glossary at www.csrsupport.com.
