Power Source
EB-X400 uses a 600 mAh Lithium-ion battery pack.
■
Main Colour TFT LCD
A 65536 colour 128 x 128 pixels full-penetration TFT LCD module.
A HD66782 chipset is used for the LCD driver.
■
Integrated Camera
As one of the most characteristic features of the EB-X400 design, an integrated digital camera is introduced.
A VGA (640 x 480 pixels) size CMOS camera module. This camera module does not have an integrated SRAM nor a JPEG
encoder.
■
16 polyphonic Melody Ringer
A new Melody generator IC ; U2011 YMU759B is used for the enhanced 16 polyphonic Melody ringer function with ADPCM.
Main features of the melody generator IC are as follows ;
8
16 multi-sounds
8
ADPCM decode function (possible to mix-play with melody data)
8
FIFO (512 byte for MIDI, 256 byte for ADPCM) and sequencer installed
8
0.4 W speaker amplifier integrated
■
IrDA
The IrDA transceiver function is added to EB-X400 to enable wireless data exchange with PCs and other handsets.
■
Real Time Clock (RTC)
Time and calendar informations provided within U2001, obviating the need for an external RTC.
The RTC has following functions:
Time counter (SEC, MIN, HOUR, WEEK, DAY, MONTH, and YEAR)
Daily/Weekly Alarm control
Time constant interrupt generator
High accuracy time correction control
■
Acoustic Components
Desktop handsfree (DTHF) operation is supported using a DTHF speaker located in the bottom of the handheld unit.
Ringing tones are also output from this speaker.
■
Headset with remote switch
A headset with remote control is available as an accessory.
This arrows the user to receive, end or place calls without opening the clamshell of the headset.
5.2.3. U2001 E-Gold + V3 (BASEBAND CHIPSET, DIGITAL AND ANALOGUE CHIP)
The U2001 (E-Gold + V3) manufactured by Infineon contains the DSP, CPU, GSM timing functions and many peripheral
functions, this LSI contains the interface circuits to the Audio, RF, SIM and auxiliary analogue functions.
■
DSP (OAK)
The DSP core is a 16-bit (data and program) high performance fixed-point DSP core and is designed for the mid to high-end
telecommunication applications, where low power and portability are still major requirements.
The core consists of a high performance central processing unit, including a full featured bit-manipulation unit, RAM and ROM
addressing units, and program control logic. The core has an improved set of DSP and general microprocessor functions to
meet the application requirements.
The DSP can be clocked at up to 78 MHz via a PLL contained within U2001 (E-Gold+ V3).
