General Description
Applications
BlueCore2-Audio
is a single chip radio and
baseband IC for BluetoothTM 2.4GHz systems.
It is implemented in 0.18
m CMOS technology.
BlueCore2-Audio has the same pinout and
electrical characteristics as available in
BlueCore2-Flash to enable development of
custom code before committing to ROM.
The 4Mbit ROM is metal programmable, which
enables a six week turn-around from approval of
firmware to production samples.
The integrated mono audio CODEC allows for
more compact designs and low power
consumption for battery powered applications.

n
High volume, cost sensitive production
BlueCore2-Audio has been designed to reduce the
number of external components required which
ensures 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 specification v1.1.
