XE1401
Ultra low power BluetoothTM Baseband Controller
for portable Data and Voice Applications
General Description
The XE1400 series is a family of highly optimized
BluetoothTM integrated circuits. The XE1400
series offers a generic BluetoothTM baseband
solution to enable your battery operated
applications with the BluetoothTM wireless
communication standard in the worldwide
available 2.4 GHz ISM band. The easy to use
XE1400 series is highly optimized for ultra low
power consumption.
The XE1401 device is a stand alone BluetoothTM
baseband protocol-on-chip solution providing the
full BluetoothTM functionality up to the Host
Controller Interface (HCI). This ultra low power
"add-on" BluetoothTM baseband solution targets
all battery powered applications with an already
existing host controller.
Applications
PCs, PDAs, Cell Phones and wireless
games, peripherals and accessories.
Headset applications.
Home surveillance and security.
Product Features
ROM based, single chip BluetoothTM baseband
add-on solution - no external memory required.
Fully integrated lower layer BluetoothTM
protocol, compliant to revision 1.1 based on
qualified NewLogicTM IP. Already prepared for
BluetoothTM revision 1.2.
Supports one SCO (HV, DV packages) and up
to three simultaneously ACL (DM, DH, AUX
packages) channels.
Supports various BluetoothTM radio chips,
e.g. SiliconWave, Skyworks.
Supports Class 1, Class 2 and Class 3 radio
modules.
High speed 4 wire UART for host processor
interfacing. Glueless audio interface to XEMICS
XE3000 CODECs.
Supply voltage range 1.8V to 3.6V, core
operating voltage 1.8V.
Ultra low power consumption, e.g. total peak
current of radio and XE1401 of below 25mA.

Preliminary Product Brief
XE1401
BluetoothTM Baseband Controller IC
The BluetoothTM Controller IC is designed to be
manufactured in a 0.18
m CMOS process. It includes
all required hardware blocks to comply with the
BluetoothTM communication standard.
The embedded baseband sequencer manages all
BluetoothTM baseband tasks of the lower layer protocol
up to the HCI (Host Controller Interface). The
baseband controller insures a "transparent" usage of
the BluetoothTM wireless communication via the HCI. It
receives the data directly from your application and
then performs the various transmits, receive and
protocol timing tasks without any interaction from the
host controller.
The radio interface gluelessly links the BluetoothTM
baseband controller IC to various Radio ICs.
Software
The XE1401 incorporates the complete lower layer
protocol software. State of the art upper layer protocol
Development Tools are provided through our partners
like IAR Systems (
www.IAR.com
).
For specific applications e.g. BluetoothTM Headsets a
complete software package can be provided including
application layer Software in ANSI C format.
Radio
The XE1401 supports several 3
rd
party radio devices
using a 13MHz or 16MHz clock and any supply voltage
between 1.8V and 3.6V.
To benefit most from the low power features of the
baseband chip, XEMICS recommends the Skyworks
(
www.SkyworksInc.com
) BluetoothTM radio CX72303.
CODEC
The XE1401 supports CODEC utilizing log. PCM as
well as CVSD (Continuous Variable Slope Delta)
coding.
Fast time to market
The XE1400 series is targeted for portable, battery
powered BluetoothTM wireless communication
applications. The Starter Kit for the XE1401 XE1401SK
- allows easy prototyping and to bring products with an
already existing host controller rapidly on the market.
XEMICS teamed up with regional BluetoothTM
Competence Centers to support clients to rapidly bring
BluetoothTM products using the XEMICS XE1400 series
on the market.
Complete BluetoothTM solution Headset
This integration example shows your application enabled
with the BluetoothTM wireless communication standard.
The ROM based BluetoothTM baseband controller XE1401
autonomously handles all lower layer BluetoothTM tasks
and hence significantly eases the system development.
Reference designs using various form factors are
available.
