1.c.3 IC600 RF-IC (Hitachi HD155121FEB).

Transceiver IC for E-GSM and DCS Dual Band cellular systems.

1.c.4 Memory system.

IC200 : Flash ROM (2MByte ) .Stores the CPU program code
IC201 : RAM (128 kByte ). Stores data for the CPU work.
IC202 : EEPROM ( 128K Byte) .Stores the user data and hardware adjustment data.

1.c.5 System Clock.

The system clock for the telephone is 13 MHz TCXO, generated by X600. It is processed in IC300 to
provide serial clock for LCD, EEPROM, and IC100. The clock is buffered in IC300 One-C, and then
fed to IC100 IPD as “ CPU CLK ” . It is available on pin 56 of IC100.
During Stand-By mode, the system clock is not managed from X600 TCXO but from X300 ( “ slow
clock ” at 32.768 kHz).

The battery is Li-ion 580mAh, 3.8v nominal for Aria
External power supply for charging (EXPS) comes from the I/O connector at the bottom side of the

mobile (AC/DC, CLA, DTC or H/F Kit). This power supply is 5.8 V nominal. Battery presence and
battery type information are accessible in CHGM IPD register. If a Ni-MH battery is detected, the
software considers that the battery is absent.

The battery temperature information (TH) is given by threshold in IPD CHGM register. This
information is used only for charge control.

The battery level information is accessible in an A/D converter in One-C. It is also available in CHGM
IPD register, this information is given by range only for range control.

External power supply (EXPS) presence information is accessible in CHGD IPD register. As
described in the drawing above, the power supply for Base Band (IC300) comes from EXPS when it is
present because EXPS level (5.8 V) is always greater than battery voltage. On the contrary, power
supply for radio always comes from the battery.

The serial diode (D107) between battery and IPD (IC100) can be bypassed by software to reduce
voltage headroom. Bypass is Activated when battery is less than 3.45 V.

2.c Charging process

Charging process follows these successive phases :
Pre charge :

This phase is mandatory before the rapid charge to verify that battery operation is normal (normal
battery voltage and temperature). Charge current during this phase is 62 mA (1/8 C). If the battery
voltage is more than 3.3 V, the S/W launch rapid charge except if the temperature is not between 0°C
and 55°C.

Rapid charge :
Charge current during this phase is 600 mA. If battery temperature becomes abnormal IPD charger
start a low current charge (1/20 C), while temperature comes back normal (between 0°C and +55°C)
during 15 mn. Full charge detection ends Rapid charge. Full charge is detected by S/W when charge
current decrease less than 50mA (full charge convergence current)

Full charge :
This phase shows that the battery is fully charged by LED Green or LCD Full charge is automatically
stopped after 24 hours duration.

2.d Main characteristics

The phone transmits only if the battery is attached to it, in any configuration of power supply. When
the phone is connected to H/F adapter, DTC, AC/DC, or CLA, the battery charging circuit operates.

Battery voltage (+3.8V) is applied via D107 or from TESTPS ( J100 pin8 ) through D101 when using
Hand Free.

The main power supply is fed to the phone either from the attached battery via the connector J101, or
from accessories :

• H/F adapter,

• Desk Top Charger DTC,

• AC/DC adapter and CLA via the external connector J100.

R107 and R108 give an internal voltage reference. If the battery voltage VBAT falls Low, then
BYPASS short out the diode D107 through TR105 to reduce voltage drop.

2.e Autonomy Control

The battery energy is displayed on the LCD by a 3 bars “battery icon” . Voltage thresholds for each
bars are calculated to have this autonomy time share out:

1 bar

97%

0 bar

40%

3 bars

A 3 times 33% time share out is not possible because of the very stable battery voltage level between
20% to 50% autonomy time. In addition with these bars, a ” low battery alarm” is displayed between
”1 bar” and the mobile off.
All these thresholds are programmed in EEprom by the factory and given in following thresholds
table.

Idle Mode Call Mode

Initial thresholds Battery level Battery level

3 bars → 2 bars
2 bars → 1 bars

1 bar → 0 bar

Power off 3.35 V 3.20 V

Thresholds are different according to the mode, Idle mode or Call mode. Idle mode threshold are
checked by software 25 mn after the end of the call.

2 bars

3.85 V 3.75 V

3.70 V 3.60 V

3.45 V 3.30 V

80%

When battery voltage is less than the thresholds given in the table above, BAT_EMPTY is true.
