General Description

The _äìÉ`çêÉ∆RJjìäíáãÉÇá~=bñíÉêå~ä is a product from

CSR's Connectivity Centre. It is a single-chip radio and

baseband IC for Bluetooth 2.4GHz systems.

BlueCore5‑Multimedia External interfaces up to 32Mb

of external flash memory. When used with the CSR

Bluetooth stack, it provides a fully compliant Bluetooth

v2.1 + EDR specification system for data and voice.

BlueCore5‑Multimedia External contains the Kalimba

DSP coprocessor with double the MIPS of

BlueCore3‑Multimedia External, supporting enhanced

audio applications.

BlueCore5‑Multimedia External is designed to reduce

the number of external components required which

ensures production costs are minimised. The device

incorporates auto-calibration and BIST routines to

simplify development, type approval and production

test.
