BlueCore ?2-Audio Product Data Sheet
General Description Applications
BlueCore2-Audio is a single chip radio and baseband IC for Bluetooth? 2.4GHz systems.It is implemented in 0.18μm 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 Headsets
n Cellular Handsets
n Personal Digital Assistants
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.
BlueCore2-Audio System Architecture
Device Features n Fully qualified Bluetooth system n Low power 1.8V operation n Minimum external components
n Integrated 1.8V regulator n 15-bit linear audio CODEC n Dual UART ports
n Available in VFBGA and LFBGA
packages
n Also available in ‘RF Plug and Go’
package for low cost manufacture

VDD_CORE, VDD_RADIO, VDD_VCO, VDD_ANA, VDD_BAL and VDD_MEM are at 1.8V unless shown otherwise.
VDD_PADS, VDD_PIO and VDD_USB are at 3.0V unless shown otherwise.
The same setting of the digital trim is applied to both XTAL_IN and XTAL_OUT.
Current drawn into a pin is defined as positive, current supplied out of a pin is defined as negative.
(1) Internal USB pull-up disabled.
(2) Specified for an output voltage between 0.2V and VDD_PIO -0.2V.
(3) Integer multiple of 250kHz.
(4) The difference between the internal capacitance at minimum and maximum settings of the internal digital trim.
(5) XTAL frequency = 16MHz; XTAL C 0 = 0.75pF; XTAL load capacitance = 8.5pF.
(6) Clock input can be any frequency between 8 and 40MHz in steps of 250kHz + CDMA/3G TCXO frequencies of 15.36, 16.2, 16.8, 19.2, 19.44, 19.68, 19.8 and 38.4MHz.
(7) Clock input can either be sinusoidal or square wave. If the peaks of the signal are below VSS_ANA or above VDD_ANA a DC blocking capacitor is required between the signal and XTAL_IN.
