Highly integrated ultra low power BluetoothTM
headset solutions from XEMICS
General Description
The XE1400 series is a family of highly optimized
BluetoothTM integrated circuits. The XE1400 series
offers generic BluetoothTM baseband solutions to
enable your battery operated applications with the
BluetoothTM wireless communication standard in the
worldwide available 2.4 GHz ISM band.
The upcoming XE143x series of products will
additionally include an on-chip voice CODEC as
well as an application controller. This product series
is highly optimized to serve all kind of BluetoothTM
headset applications. All devices are designed for
ultra low power consumption as well as low cost
.
The intention of the XE143x series is to offer a very
high level of integration requiring a minimum of
external components to build up a complete
BluetoothTM wireless headset.
By combining one of our Headset specific
BluetoothTM Baseband Controllers with a 3
rd
party
2.4GHz radio device (e.g. Conexant CX72303) an
ultra low power BluetoothTM solution can be built
consuming less than 20mW @1.8V (HV3).
Applications
BluetoothTM headset
Cell phones
General wireless human interface applications.

Preliminary Product Brief
XE143x - BluetoothTM headset
Headset controller IC
The BluetoothTM Headset Controller IC series,
XE143x, includes the XEMICS BluetoothTM
baseband Controller, the XEMICS CODEC as well
as a micro-controller for upper layer BluetoothTM
and application software.
The on chip application controller is based on
XEMICS' proprietary micro-controller, the
CoolRISCTM. The embedded controller operates
totally independent from the BluetoothTM
sequencer.
The on chip voice CODEC enables a complete
headset solution with only a few external
components.
Software
Some devices of XE143x series even incorporate
the complete BluetoothTM protocol stack software.
State of the art Development Tools will be provided
by our partners to program and configure the target
devices.
Radio
The XE143x devices will supports several 3
rd
party
radio devices. To benefit most from the low power
features of the baseband chip, XEMICS
recommends the Conexant CX72303 BluetoothTM
transceiver.
Reference Design
XEMICS will offer reference designs demonstrating
the XE143x technology and a way to implement it
into a Bluetooth Headset application.
The OEM will then be able to focus on design
integration rather than complex product
development.
