XE1400 series
The XEMICS EasyBlue™ devices offers both generic, as well as
application specific Bluetooth baseband solutions tailored to all kind of
battery powered applications. The generic XE140x devices can be used to
enable any existing application with the Bluetooth communication standard.
If cost and performance optimized Bluetooth solutions for specific, battery
operated, applications are required XEMICS' provides the solutions.
XE1401
Ultra Low Power Bluetooth baseband controller
XE1431
Ultra Low Power Bluetooth headset solution
XE1401
Ultra Low Power Bluetooth baseband controller
The XE1401 device is a stand-alone Bluetooth baseband protocol-on-chip
solution providing full Bluetooth functionality from the radio interface up
to the Host Controller Interface (HCI). This ultra low power ''add-on''
Bluetooth baseband device targets all battery powered applications with an
already existing host controller.

XE1431
Ultra Low Power Bluetooth headset solution
The XE1430 series additionally includes an on chip voice CODEC as well
as an fully integrated application controller, both are optimized for ultra
low power consumption and low cost. The XE1431 offers a high level of
integration and with only a few external components a complete Bluetooth
wireless headset solution can be built. By combining the XEMICS ''Bluetooth
Headset device'' XE1431 with a 3rd party 2.4GHz radio device ( e.g.
Conexant 72303 ) a real ultra low power Bluetooth headset consuming less
than 35mW (HV3) @1.8V can be realized.
• Single chip Bluetooth headset baseband solution including
application controller and voice CODEC
• Fully integrated lower layer Bluetooth protocol, compliant to revision
1.1 based on qualified NewLogic™ IP
• On-chip 8-bit ultra low power host controller for application and upper
protocol layers Bluetooth tasks
• Direct connection to the microphone and speaker
• Supports one SCO and up to three ACL simultaneous channels
• Various Bluetooth radio interfaces implemented, e.g. Conexant radio
CX72230x
• Supports Class 1, Class 2 and Class 3 radio modules
• Minimum of external components required
• Small form factor - BGA
• Core operating voltage 1.8V
• Ultra low power consumption, below 5mA@1.8V

9, 2001 XEMICS unveils world's
lowest power ''SANDMAN CODEC'' geared to Bluetooth applications
XE3000
Series Development Tools > XE3000DVK
The XE3000DVK is a comprehensive development tool for the complete
XE3000 series. Due to the on board microphone and an optical, digital audio
interface the user is able to evaluate the complete XE3000 series in a
typical voice as well as a typical audio environment. Programming Software
based on a self explanatory graphical user interface to configure the
XE3000 is included.

XEMICS
XE3000 Product Selector (ADC, DAC, Codecs)
XE3000 CODECs combine microphone supply and power amplifier into a tiny
TSSOP package. At a tiny power budget too: 2 mW, 1.8 V. Talking about
power, the unique ''Sandman™'' function puts the whole application to
sleep until an audio signal is detected.
XE3003
A miniature ADC with programable pre-amplifier and microphone bias source.
XE3004
A miniature DAC with 100 mA peak current power amplifier
XE3005
The complete audio CODEC combining XE3003 and XE3004 features
XE3005 is a fully integrated voice / audio CODEC. It contains all
functions required for voice / audio microphone drive and amplification,
16 bit sigma-delta ADC, 16-bit PWM DAC and power amplifier. The Serial
Audio Interface supports (SFS) Short Frame Sychronisation and (LFS) Long
Frame Synchronisation digital audio formats.
• 16 bit sigma-delta ADC, 80 dB SNR
• ADC sampling rate 4 - 48 kHz
• 16 bit PWM DAC, 60 dB SNR
• DAC sampling rate 4 - 48 kHz
• Microphone supply 1.6 V / 1 mA and 1.1 V / 50 uA
• on-chip power amplifier, peak current 100 mA max.
• 1.8 - 3.3 V, 0.4 mA typ. (no load)
• TSSOP 20
XE3006
The Sandman CODEC : XE3005 with audio-detect function
XE3006 equals the XE3005 plus two Sandman™ outputs. The Sandman
function is an audio signal detection function for example allowing an
audio processor in the application to sleep until a relevant audio signal
is detected.
• Sandman™ outputs for automatic audio signal detection
• 16 bit sigma-delta ADC, 80 dB SNR
• ADC sampling rate 4 - 48 kHz
• 16 bit PWM DAC, 60 dB SNR
• DAC sampling rate 4 - 48 kHz
• Microphone supply 1.6 V / 1 mA and 1.1 V / 50 uA
• On-chip power amplifier, peak current 100 mA max.
• 1.8 - 3.3 V, 0.4 mA typ. @fs=20kHz (no load)
• TSSOP 24
