General Description
Applications
_`QJolj is a single chip radio and
baseband IC for Bluetooth 2.4GHz systems
including enhanced data rates (EDR) to 3Mbps.
With the on-chip CSR Bluetooth software stack it
provides a fully compliant Bluetooth system to v2.0
of the specification for data and voice
communications.

BlueCore4-ROM System Architecture
BlueCore4-ROM has been designed to reduce the number
of external components required which 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
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.
