Applications

■

High-end wired/wireless stereo headphones

■

High-end wired/wireless stereo headsets

■

High-end wired/wireless active headsets

■

Wireless stereo speakers

■

Low-end docking stations and soundbars

■

Gaming headsets

The dual-core architecture with flash memory enables

manufacturers to easily differentiate their products with

new features without extending development cycles.

The enhanced Kalimba DSP coprocessor with up to

120 MIPS supports more digital signal processing

requirements in stereo headphones, headsets, gaming

headsets and soundbars.

The audio codec supports 2 ADC channels, up to 6

microphone inputs, stereo output and a variety of audio

standards.

CSR's popular BlueCore

CSR8670

™

and

BlueCore

5‑Multimedia platforms are

software‑portable to the CSR8675 BGA, with easy

migration of a broad range of solutions from CSR's

eXtension partners. This enables rapid time-to-market

deployment for a broad range of consumer electronic

products.
