XE1402
Ultra low power BluetoothTM Baseband Controller
for portable Data 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 XE1402 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.
Medical, home surveillance and security
applications.
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 up to seven simultaneously ACL (DM,
DH, AUX packages) channels SCO
connections are NOT supported.
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. Generic Serial interface (SPI) to
external peripherals.
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 XE1402 of below 25mA.

Preliminary Product Brief
XE1402
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 will manage 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 XE1402 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. Cable replacement
(Serial Port communication) a software package can
be provided including application layer Software in
ANSI C format.
Radio
The XE1402 supports several 3
rd
party radio devices.
To benefit most from the low power features of the
baseband chip, XEMICS recommends the Skyworks
(
www.SkyworksInc.com
) BluetoothTM radio
SPI
The on chip generic SPI is fully transparent via the HCI
and allows to communicate to external peripherals like
non-volatile memory and sensors. The on chip boot-
loader can be used to automatically initialize the
complete system up to the application layer.
Fast time to market
The XE1400 series is targeted for portable, battery
powered BluetoothTM wireless communication
applications. The XE1402 allows easy prototyping to bring
products with an already existing host controller rapidly on
the market.
XEMICS teamed up with several regional BluetoothTM
Competence Centers to locally support clients to rapidly
bring BluetoothTM products using the XEMICS XE1400
series on the market.
Complete BluetoothTM solution serial port
communication
This integration example shows your application enabled
with BluetoothTM wireless communication standard.
The ROM based BluetoothTM baseband controller XE1402
autonomously handles all lower layer BluetoothTM tasks
and hence significantly eases the system development.
Reference designs using various form factors are
available.
