BlueCore4-ROM CSP is designed to reduce the number
of external components required. This ensures that
production costs are minimised.
The device incorporates auto-calibration and built-in
self-test (BIST) routines to simplify development, type
approval and production test. All hardware and device
firmware is fully compliant with the Bluetooth v2.0 + EDR
Specification (all mandatory and optional features).
To improve the performance of both Bluetooth and
802.11b/g co-located systems a wide range of
co-existence features are available including a variety of
hardware signalling: basic activity signalling and Intel
WCS activity and channel signalling.
