General Description
The BlueCore® CSR8670™ BGA consumer audio
platform for wired and wireless applications integrates
an ultra-low-power DSP and application processor
with embedded flash memory, a high-performance
stereo codec, a power management subsystem, LED
and LCD drivers and capacitive touch sensor inputs in
a SOC IC. The dual-core architecture with flash
memory enables manufacturers to easily differentiate
their products with new features without extending
development cycles.
CSR's popular BlueCore5-Multimedia® platform is
software-portable to the BlueCore® CSR8670™ BGA,
with easy migration of a broad range of solutions from
CSR's eXtension partners. This migration enables
rapid time-to-market deployment of a broad range of
consumer electronics products.
The enhanced Kalimba DSP coprocessor with
80MIPS supports enhanced audio and DSP
applications.
