Gateways
BlueCore5‑Multimedia External contains the Kalimba
DSP co-processor 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.
To improve the performance of both Bluetooth and
IEEE 802.11b/g co-located systems a wide range of
coexistence features are available including a variety
of hardware signalling: basic activity signalling, Intel
WCS activity and channel signalling.
For additional information about the
BlueCore5‑Multimedia External refer to the
BlueCore5‑Multimedia External Product Data Sheet
