■ General

RF circuit design is built based on SKYWORKS-74963 direction conversion transceiver IC integrated by SAW filters, power
amplifier with control circuit, and Transmitter/receiver switch.
RF LO always requires external frequency sources with VCTCXO. And LO frequency is periodically re-tuning to synchronize
with cell or network.

■ Antenna

EB-A100 uses Helical-type antenna, which is most low-cost, monopole-like antenna. The antenna takes different spacing to
define bands of GSM, DCS and PCS.

5.2.5. CPU Memory

To reduce component space, the phone uses a BGA package with Dual operation Flash memory and SRAM MCP.
The following memory configuration is used:
64Mbits Flash memory organized as 4M * 16bits or 8M * 8bits
32Mbits Pseudo RAM organized as 256K * 16 bits

5.2.6. LCD

The LCD module consists of a LCD glass, white LED and driver chip connection to the Main PCB via a flexible PCB strip.
Resolution: 112 x 64 pixels. It can accommodate Chinese and large character sets.

The LCD driver is controlled by setting the command register through the AD6525 u-wire interface and an I/O line
that distinguishes between command or data. To send data or a command to the display driver, the nDISPLAYCS
line is used for chip select. LCD_CTL is set high to send data and set low to send commands.

5.2.7. Real Tim Clock (RTC)

Clock functions are provided by a Real Time Clock built into AD6525. The module is synchronized by a 32.768 kHz crystal and
has a backup power source provided by a capacitor. AD6525 has a clock auto compensation function to take into account any
inaccuracies of the crystal. This is able to calibrate out crystal tolerance / drift by writing to the compensation registers.
This functionality allows the application software to implement standard, calendar, or organizer functions such as:
Time and date display
Programmable alarm
Programmable mobile activation
The RTC interrupt is routed through the IRQ-controller to the MCU or the DSP, as defined by
software in interrupt configuration registers.

The battery comprises a single Lithium-Ion (Li-Ion) cell with a nominal voltage of 3.7 V and 780-mAh capacity.
This type of battery has an advantage in weight and size over Nickel Metal Hydride (NiMH) cells.

5.4.2. Regulator Control

The voltage regulators and the reference are enabled based on the status of the battery and input from the user or software.
If the AD6537 is in Deep Discharge Lockout (DDLO) or Under-Voltage Lockout (UVLO) only the Real-Time Clock regulator is
active. If the AD6537 is in Thermal Shutdown only the Real-Time Clock regulator is active.
If the battery is not in Deep Discharge Lockout, Under-Voltage Lockout, or Thermal Shutdown, the Real-Time Clock regulator
and the the reference are always enabled. The other regulators are enabled or disabled based on input from the user or
software. If the user presses the power-on key (KEYON), the regulators required to boot the software are enabled.If a charger is
detected(CHGDET) the regulators required to boot the software are enabled. If the software asserts the DBBON signal the
regulators reguired to maintain the software state are enabled. The VCXOEN signal enables the VCXO regulator.
The analog regulators can be enabled and disabled using CSPORT.

5.4.3. Voltage Regulation

Each power source is specified as follows.

■ Digital Core LDO (VCORE)
The digital core LDO supplies the baseband circuitry in the handset (baseband processor and baseband converter). The LDO
has been optimized for very low quiescent current at light loads as this LDO is on whenever the handset is switched on.

– 5-13 –

■ Memory LDO (VMEM)

The memory LDO supplies the system memory as well as the subsystems of the baseband processor including
memory IO, display, and melody interfaces. It is capable of delivering up to 150 mA of current and is available for
either 1.8 V or 3 V based systems. The LDO has also been optimized for low quiescent current and will power up
at the same time as the core LDO.

■ External InterfaceLDO (VEXT)

This LDO has the same features as the core LDO. It has furthermore been optimized for good low frequency ripple rejection for
use with the baseband converter sections in order to reject the ripple coming from the RF power amplifier. VEXT is rated to
170 mA, which is sufficient to supply the analog section of the baseband converter such as the AD6537, as well as the speaker.

■ TCXO LDO (VTCXO)

The TCXO LDO is intended as a supply for a temperature compensated crystal oscillator, which needs its own ultra-low noise
supply. VTCXO is rated for 20 mA of output current and is turned on along with the analog LDO when TCXOEN is asserted.

■ RTC LDO (VRTC)

The RTC LDO is capable of charging rechargeable Lithium or capacitor-type backup coin cells to run the real-time clock module.
The RTC LDO supplies current both for charging the coin cell and for the RTC module. In addition it features a very low
quiescent current since this LDO is running all the time, even when the handset is switched off. It also has reverse current
protection with low leakage, which is needed when the main battery is removed and the coin cell supplies the RTC module.

■ Microphone LDO (VMIC)

The Microphone LDO generates the voltage needed for 2.5V Microphone. It is rated for 1 mA of supply current.
The Microphone regulator supplies the microphone interface circuitry.
The Microphone regulator is optimized for extremely high rejection up to 217 Hz and low noise.

■ SIM LDO (VSIM)

The SIM LDO generates the voltage needed for 1.8 V or 3 V SIMs. It is rated for 20 mA of supply current and can be controlled
completely independently of the other LDOs.
Applying a low to SIMEN shuts down the SIM LDO. A discharge circuit is active when SIMEN is low.
This pulls the SIM LDO's output down when the LDO is disabled. SIMVSEL allows the SIM LDO to be programmed for either

1.8 V or 2.8V. Asserting a high on SIMVSEL sets the output for 2.8 V.
SIMEN and SIMVSEL allow the baseband processor to properly sequence the SIM supply when determining which type of SIM
module is present.

– 5-14 –

5.5. Battery Charging and Monitoring

5.5.1. Charging Current

The status of the LCD battery icon is determined by the value of ADC0 returned from AD6521, as indicated in the table:

Battery Pack

Li-lon
3 bar 3.65 V < < 3.95 V
2 bar 3.54 V < < 3.65 V
1 bar 3.3 V < < 3.54 V
Low Voltage Alarm < 3.3 V

The phone will power down two minutes after generating a Low battery Alarm.
Battery charging is controlled by the CPU within the phone. If external power is detected and the temperature is within specified
limits, the charger starts the rapid charge algorithm.
When the battery is fitted, the charging algorithm is determined by constant voltage and constant current control with time,
temperature and voltage safeguards. A current limit no greater than the maximum charge current for any battery option must be
provided by the external power source.

5.5.2. Deeply Discharged Batteries

In the case of deeply discharged batteries, there may not be enough power in the battery to initiate charging. In this case, the
charging circuit automatically starts to trickle charge the battery until there is enough power to switch on the phone.
