INTRODUCTION

1.1 DESCRIPTION

BDP-8670 is a Bluetooth sub-system using CSR8670 chipset from Cambrige Silicon Radio.

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 in a SOC IC.

BDP-8670 is slim and light so the designers can have better flexibilities for the product shapes.
