It is a single-chip radio and baseband IC for Bluetooth 2.4GHz systems including basic rate, EDR to 3Mbps and Bluetooth low energy. The low-cost QFN package and 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 system and production costs. The battery charger architecture enables the CSR8605 QFN to independently operate from the charger supply, ensuring dependable operation for all battery conditions. Bluetooth mono speakers A2DP audio sink (including multipoint) for music streaming The enhanced Kalimba DSP coprocessor with 80MIPS supports enhanced audio and DSP applications. The integrated audio codec supports mono line input and mono output, as well as a variety of audio standards. Full AVRCP v1.0 support enables music play / pause and forward / rewind functionality with assured IOP coverage. Support for simple Android-based Apps enables options to differentiate user applications, e.g. battery status monitoring.
