General Description
CSR's BlueCore® CSR8635 QFN is a single-chip
Bluetooth ROM audio solution for rapid evaluation and
development of Bluetooth ROM stereo applications.
BlueCore® CSR8635 QFN consumer audio platform for
wired and wireless applications using the QFN package
integrates an ultra-low power DSP and application
processor with embedded flash memory, a high-
performance stereo codec, a power management
subsystem and LED drivers.
The CSR configuration tools and the development kit
provide a flexible and powerful development platform to
design advanced and high-quality Bluetooth stereo
products using BlueCore® CSR8635 QFN single-chip
Bluetooth audio solution.
