General Description
The _äìÉ`çêÉRJjìäíáãÉÇá~=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.
