Product Overview
Features
The A008 (E MEA) A6188+ (Asia) is a GSM dual band (900/1800 MHz) GPRS
product, and is an enhanced version of A6188. From this point onwards we will
refer to this product as the A008. The A008 is mechanically very similar to the
existing A6188 form factor with slight modifications made to the flip and front
Housing to ensure a different look.
The display will be 320 x 240 pixels, 4 level gray scale ¼ VGA display. The
display shall be 24 x 24 bitmap for Chinese Characters and 15 x 16 bitmap for
English Characters. The line spacing has been modified for easier reading.
There will be 2 new Colours, Mica Grey, Summer Sky Blue/TT silver
In additional to the existing A6188 User Interface features the following features /
applications will be available
GPRS – General Packet Radio service
GPRS (General Packet Radio Service) is a combination of HSCSD (High Speed
Circuit Switched Data) and SMS (Short Message Service). It has a theoretical
speed of 171.2kbps compared with 9.6kbps as today. A single user using all 8
uplink timeslots and all 8 Downlink timeslots could theoretically achieve this.
The main purpose for GPRS is to give ‘immediacy’ to the customer i.e. to allow
the customer access to data transfer as and when they need it.
Information will be carried across as IP from Internet sites etc…
For GPRS the Traffic Channel (TCH) now becomes the Packet Data Channel

BCH
As can be seen from the above drawing, up to 8 different users can occupy 1
single timeslot at any given time. The more Bandwidth that is required, the more
channels are allocated by the network.
This extra timeslot allocation is only given when the network is not busy, and
therefore dynamically maximises idle network resources. Also because much of
the SMS messaging will now be carried over the GPRS system this will relive
much of the SMS Centre loading.
Also the Uplink and Downlink are now completely separate channels in that we
can now have an uplink only and downlink only channel allocated by the network.
GPRS is high bandwidth data split at source into separate but related data
‘packets’. The information packets that a GPRS enabled phone is to receive, is
addressed specifically for that phone using a TFI - Temporary Flag Indicator.
And although the phone will ‘listen’ to each timeslot of data but will only decode
the information that is highlighted by a matching TFI.
By setting a USF – Uplink Status Flag
on a Downlink timeslot, the mobile
phone is instructed it can transmit on the next available uplink timeslot.
GPRS will support GSM 900 / 1800 / 1900 as well as TDMA technologies
For GPRS to operate the following must be available:
• Mobile phone must be of GPRS technology
• Network provider must support GPRS which includes a modified
Infrastructure (Core Network)
GPRS can be set up manually through the UI or using the PC Tools programming
equipment. The A008 will be a 1 up 2 down GPRS technology i.e. it supports 2
timeslots of Downlink information per Frame and 1 uplink slot.

WAP Format is derived as follows
1. The request for information is made in WML (Wireless Mark-Up Language)
derived from HTML.
2. Request is passed to WAP Gateway, which retrieves the information from the
server in standard HTML (which is then filtered to WML) or if available
WML format.
3. The information is then passed the cellular user, via the cellular network
provider.
All settable parameters can be entered manually or programmed using PC Tools

Picasso
Factory label for Leap
Picasso is the new factory tracking system. It is being implemented globally in all Motorola and out-sourcing
manufacturing sites throughout 2000. For all field failures, Service currently records the MSN to validate the
warranty period and record which site shipped the phone. By recording the Picasso number in addition to the
MSN, we can perform the normal validations but also attribute all field failures back to original site, shift and
line of manufacture.

RF: Receive
1) The RF Signal from the base station is received through the Antenna A1 and is fed to
RF Switch U101, This connects RF to the Aux RF port or the antenna, and isolates
TX from RX. The switch is controlled primarily by the following signals SW_RF:
This is a 50Ω load signal from Pin 2 of the Accessory Socket J600, when an external
device is attached. RX / TX isolation is achieved using the negatively biased signals
from Q101 and Q102. These devices use the signals MIX_275 (RX_EN + RF_V2
through Q340) and PAC_275 (TX_EN + RF_V2 through Q321 and Q320) to
produce the Transmit and Receive switching signals. The negative bias is produced
using -5V through Q104, Q105, these 2 transistors are used to provide the RF Switch
with the correct switching voltages (for RX Mode 0 – 2.7V, for TX Mode –5V to
2.7V) and Q106 is used to change the output path between Antenna and Buttplug.
The control signals from Q101 and Q102 are then fed to Pins 2 and 9 of the RF
switch. These 3 signals, supported by the voltages GSM_LNA275 (MIX_275 +
GSM_SEL) and DCS_LNAS275 (DCS_SEL and MIX_275) both through Q342
select whether the signal is Transmitted or Received.
2) Provided MIX_275 is high, then the received signal will be passed to the band pass
filter FL460, for GSM 900 and to FL450 for GSM 1800. The filters will then pass the
frequency range (GSM 1800 or GSM900), and remove any existing harmonics or
other unwanted frequencies.
3) The signal will be fed into the appropriate Low noise Amplifier Circuit, Q461 for
GSM 900 and Q451 for DCS. This part of the circuit is critical in the achievement of
a very low signal to noise ratio, therefore as can be seen around the actual amplifiers,
a large amount of external frequency matching and noise reduction circuitry is
involved. The LNA’s are supported by MIX_275 and are biased on or off by
GSM_LNA275 for Q461and DCS_LNAS275 for Q451.
4) The appropriate signal is then fed onto FL470 (For GSM 900 or FL465 (For GSM
1800) where any harmonics created during amplification are removed.
5) The amplified signal is now injected to the base of the dual transistor mixer Q1254.
Both mixers are supported by MIX_275 (Q340).The tuned emitter biasing voltage is
provided by GSM_LNA275 (Q342) and DCS_LNA275 (Q342)
6) The RX VCO Varactor CR250. Is the active component used within the RX VCO,
basically a Varactor diode works in the following way:
When a reverse voltage is applid to a PN junction , the holes in the p-region are
attracted to the anode terminal and electrons in the n-region are attracted to the
cathode terminal creating a region where there is little current.This region ,the
depletion region, is essentially devoid of carriers and behaves as the dielectric of a
capacitor.
The depletion region increases as reverse voltage across it increases; and since
capacitance varies inversely as dielectic thickness, the junction capacitance will
Motorola Internal Use

A008 / A6188+ – Circuit Description
decrease as the voltage across the PN junction increases. So by varying the reverse
voltage across a PN junction the junction capacitance can be varied .This is shown in
the typical varactor voltage-capacitance curve below. Fig 6.1. This variable
N
P

capacitence can then be used along with the inductive strip (PCB Tracks lying very
close) to provide a LC tuning resonant circuit.
The tuning voltage for the varactor is provided by CP_RX (MAGIC U913 Pin A1).
The VCO amplification is made up of 3 transistor stages Q253, Q255 and Q262, these
are supported by the voltage RVCO_250 (SF_OUT through Q344). The collector
output from Q255 provides the Phase locked loop feedback to the MAGIC IC Pin A3,
to ensure the RX VCO frequency changes in line with the Received signal to give the
correct IF.
7) Within the mixer, the received frequency and the RX VCO frequencies are mixed
sum and difference signals are created, it will be the difference signal of 400Mhz that
will be created.
8) The – IF, is now fed to the SAW FL457 filter (Surface Acoustic Wave), this filter is
the same as was used in previous 400MHz products. The purpose of the SAW filter is
to provide comprehensive removal of harmonics created during the mixing process.
The reason the IF was changed from 215Mhz to 400Mhz was for the following
reason:

The above table demonstrates that if 215Mhz were used instead of 400Mhz, the RX
VCO would be required to operate over an extra 370Mhz. With this need eliminated,
the part count and therefore the cost are reduced.
9) The 400Mhz IF signal is then passed to the Isolation Amplifier Q490
The purpose of an Isolation Amp is to couple an analogue signal to adjoining parts of
a circuit with 2 different grounds. Also to protect the base band signals produced in
MAGIC from any stray RF. The Isolation Amp is supported by SW_VCC (MAGIC
U200 Pin C7)

Different Earthing Points
10) The signal is then passed to the MAGIC IC U200 PRE IN Pin A7
11) The signal is demodulated internally using an external Varactor diode RX Local
Oscillator set up CR259, which is driven by LO2 CP Pin A9 of MAGIC U200.
12) Where in earlier products, we used to have RX RXQ, and I these signals are now
only used in digital form within the MAGIC and cannot be measured without
technical set up. The demodulated signal is now converted internally to digital form
to be passed along an RX SPI bus to the Whitecap.
13) The RX SPI signal is made up of BDR (Base band Data Receive), BFSR (Base band
Frame Synch Receive) and BCLKR (Base band Clock Receive, fed from MAGIC
Pins G8, G9 and F7 respectively.
14) The Whitecap U800 receives these signals on Pins A3, D4 and B4, within the
Whitecap the signal is digitally processed. Baud rate reduced, Error correction bits
removed, etc…
15) The digital signal is now being fed down the DIG_AUD SPI bus to the GCAP II
U900, internally to the GCAP, the digital signal is converted to analogue and
distributed to the correct outputs
16) For Earpiece, from GCAP II Pins H6 and H7 to Speaker Pads J9833 Pins 1 and 2
17) The Alert is generated within the Dragon ball IC U2000, and not GCAP II given the
appropriate data from the incoming signal, SMS, call etc… an interrupt from the alert
is fed back to the GCAP, via the signal SPEAK_TP915. This signal is supported by
the signal PDA_VCC (ALRT_VCC (Q938 on AL) to SECOND_VCC (PDA) and
then to PDA_VCC through Q9800.
18) For the headset only the SPKR- signal is used GCAP II Pin H6 and feeds the
Headset Connector J650, Pin 3.
RF: Transmit
1) There are 2 Mic inputs, firstly from the Xcvr mic J910 Pin 2, where the analogue
input is fed to the GCAP II U900 Pin J2
2) Secondly the analogue voice can be fed from the Aux Mic attached to the headset and
will be routed from connection 1 of the Headset Jack J504, through to GCAP II, Pin
H3. The Aux mic input is amplified through U980 which is supported by
BOOM_PWR (BOOM_EN-Whitecap +V2)
3) Within the GCAP II the analogue audio will be converted to digital and clocked out
onto the DIG_AUD SPI bus to the Whitecap U800.
4) It is within the Whitecap that all information about the transmission burst is
formulated i.e. The timing of the burst / The channel to transmit on / The error
correction protocol / In which frame the information will be carried to the base
station, etc, etc…
5) All this information is then added to the digitised audio and is transferred to the
MAGIC U200 along the TX SPI bus. The bus is made up of BCLKX (Base band
Clock Transmit) Pin B3 and BDX (Base band Data Transmit) Pin B6. The timing for
Motorola Internal Use

A008 / A6188+ – Circuit Description
this data is already decided for the transmission burst, and therefore a frame synch is
not required.
6) The SPI bus signals enters into the MAGIC at Pin G7 (BCLKX) and Pin J2 (BDX)
7) The operation of the MAGIC is very complex and with respect to the transmit path,
integrates the functions of the Modem and its function of GMSK (Gaussian Minimum
Shift Keying) and also the functions of the TIC (Translational Integrated Circuit).
8) A very basic block view of how the transmit path works within the MAGIC is
demonstrated in: Fig 8.1

9) The data is transmitted from Whitecap to MAGIC on TX SPI bus BDX, within the
MAGIC each bit of data is clocked into a register. The clocked bit and the 3
preceding bits on the register are then clocked into the look up ROM, which looks at
the digital word and from that information downloads the appropriate GSMK digital
representation. Channel information and AFC information from MAGIC SPI is then
added to this new digital word, this word is then representative of the TX IF
frequency of GIFSYN products. As in the case of the TIC, the TX frequency
feedback and the RX VCO frequency are mixed to give a difference signal, this is
digitally phase compared with the ‘modulation’ from the look up ROM. The
difference creates a DC error voltage TX_CP that forms part of the TX Phase locked
loop.
10) The error correction voltage CP_TX is then fed from Pin B1 of MAGIC to Pin 8 of
the TX VCO IC U250, adjoining this line is the loop filter (See Loop Filter document
on the GSM Service Support Website).
Motorola Internal Use

A008 / A6188+ – Circuit Description
11) The Loop filter comprises mainly of U200 / Q201 / Q202 and C205 and it’s main
function is to ‘smooth’ out any overshoots when the channel is changed, see Fig 11.1.
If this overshoot were fed to the TX VCO the resulting burst would not meet the
world standards for GSM with respect to bandwidth, see Fig 11.2.

12) The Loop filter basically acts then as a huge capacitor and resistor to give a long CR
time for smoothing. It uses a small capacitor and the very high input impedance
buffer Op-Amp. During the TX_EN (Whitecap) period when the transmitter is
preparing to operate the capacitor charges, then on receipt of DM_CS (Whitecap)
when the Transmitter actually fires; the capacitor discharges through the Op-Amp
giving a smooth tuning voltage, carrying modulation to the TX VCO. The support
voltage for the Loop filter is V1_FILT (V1 + MAGIC Pin C2).
13) The TX VCO IC now creates our required output frequency with the support signals
D_TX_VCO (DCS_SEL (MAGIC Pin C4) +TVCO_250 (Q343) through Q333) and
G_TX_VCO (GSM_SEL (U201) +TVCO_250 (Q343) through Q333), to enable
either GSM or DCS frequency production and the IC Power is supported by SF_OUT
(MAGIC).
14) The output signal is now split with a sample sent back to MAGIC to control the TX
Phase locked loop
15) The remaining signal is then fed out through a pre amplifier Q455, which is supported
via PAC_275
16) To prevent the output frequency from the TX VCO before stabilisation has occurred,
being amplified and transmitted, there are Isolation Diodes CR300 (DCS) and CR301
(GSM) placed. This is biased ‘on’ by the exciter voltage from the PAC IC U350
(Power Amplifier Control IC); Pin 7 this allows the TX output frequency through to
the Exciter stages Q300 and Q400 respectively and at same time gives more or less
drive to the exciter stage via Q301 (supported by G_TX_VCO and D_TX_VCO)
The exciter stages are supported by PA B+ (B+ and PAC_275 through Q330.
17) The signal is then fed to a two separate uni-stage, narrow bandwidth Integrated PA’s
made up from Q300 (DCS) and Q400 (GSM), these are driven by the exciter voltage
from the PAC IC, and supported by PA_B+. Name changes to DCS_PA_B+ for
U400. The PA is negatively biased using –5V_SW and for GSM using the transistor
network Q303, Q304 and Q301, for DCS using Q302, Q303 and Q301.

A008 / A6188+ – Circuit Description
18) PA matching is achieved using the MCIC Filter FL300 and the signal
GSM_PINDIODE (-5V and DCS_SEL through Q322). The signal switches in or out
tuning stubs within the MCIC to provide correct matching. The MCIC filter also
samples off part of the transmitted power to feed back to the PAC IC U340
19) The signal now goes through FL1000, FL1000 is a low pass filter, filtering 2nd and 3rd
harmonics of GSM and DCS frequencies.
20) The amplified signal is then fed through to the RF switch U101, which again is
controlled as was discussed in Receive, then passed to the Antenna A1/ Accessory
Socket Switch J600
RF: Power Control Operation
1) The PAC IC U350 (Power Amplifier Control Integrated Circuit) controls the power
control of the transmitter. Below is a list of the main signals associated with the PAC
IC and their purposes.
2) The RF detector (RF_IN Pin 2) provides a DC level proportional to the peak RF
voltage out of the power amplifier, this is taken via an inductive strip from the output
of the PA Q370.
3) DET_SW Pin 11. This pin controls the variable gain stage connected between the RF
detector and the integrator. The gain of the variable stage will be unity when
DET_SW is low and will be 3 when DET_SW is high (floating).
4) TX_KEY Pin 10. This signal is used to ‘pre-charge’ the Exciter and P.A. and occurs
20µS before the start of the transmit pulse.
5) EXC Pin 7.This output drives the power control port of the exciter. An increase of
this voltage will cause the exciter to increase its output power.
6) SAT_DET Pin 12. If the feedback signal from the RF detector lags too far behind the
AOC signal then this output will go low, indicating that the loop in at or near
saturation. This signals the DSP to reduce the AOC_DRIVE signal until SAT_DET
rises. See Fig 6.1
7) AOC_DRIVE Pin 8. The voltage on this pin will determine the output power of the
transmitter. Under normal conditions the control loop will adjust the voltage on EXC
so that the power level presented to the RF detector results in equality of the voltage
present at INT and AOC. The input level will be between 0 and 2.5V.
8) ACT Pin 9. This pin will hold a high voltage when no RF is present. Once the RF
level increases enough to cause the detector to rise a few millivolts then this output
will go low. In the GSM radio a resistor is routed between this point and the AOC
input to cause the radio to ramp up the power until the detector goes active.

Logic: Power Up sequence
1) The power up sequence is very similar to Kramer with the 2 sources of power being
the battery which is a slim version of the Zap battery (SNN5713A), or using an
External B+ source. The unit will not operate without the battery.
2) The battery component consists of 4 output leads: serial data, ground, power supply
(+) and temperature sensor.
•
BATT_SER_DATA: J613. It connects to Whitecap Pin H5 to be used to
communicate both ways with the internal EEprom on the battery. This is used to
determine if the battery is authentic and what the battery charging profile is to be
used. (Sometimes known as OWDAT)
•
Ground: J612. It connects to be used as the reference ground
•
BATT +: J611. It provides the main PCB with source voltage. The voltage range of
A008 battery is from 1.4 VDC (after discharging) to 5.1 VDC (after charging).
•
BATT_THERM: J610. Is used to determine the temperature of the battery. The
temperature of the battery determines the end of the battery charging cycle. In order
to protect the charging circuit, this line will be measured constantly during the
charging period by GCAP II (U900 Pin B3)
THERM: This is used to ensure that a battery is present when the phone is powered
up, therefore ensuring the SIM card cannot be removed whilst the unit is powered up.
(Q628 is used to reduce standby current)
The A008 will use two types of charging batteries– Ni-MH battery and Li-ION
battery. The unit derives its power from the battery in the following way, BATT + is

controlled through Battery FET Q942 by GCAP II Output Pin F10 and is output as
B+
2) Once B+ is available the unit carries out the following checks:
• The battery temperature is monitored to establish whether rapid charge is required,
(J610 BATT_THERM_AD to GCAP II Pin B3)
-40 deg C – 2.75V
25 deg C – 1.39V
40 deg C – 0.96V
• Charger sensed (J600 Pin 5 MANTEST_AD to GCAP II Pin A1) This is achieved
using different sense resistors within the accessory.
For DHFA Charger - 2.75V
For Fast Charger – 2.13V
• Senses battery voltage (GCAP II Pin F7 – BATT+)
• Senses input B+ level GCAP II Pin E10 – B+)
If EXT B+ is available the current will be passed through protection diode CR940
and output as B+ to provide power to the PCB.
3) The GCAP II is programmed to Boost mode (5.6V) by PGM0 Pin G7 and PGM1
Pin G8 both being tied to Ground. Once B+ is applied to GCAP II Pin K5, all the
appropriate voltages to supply the circuit are provided. These are:
• V1 – Programmed to 5.0V. V1 is at 2.775V at immediate power on, but is ‘boosted’
to 5.0V through the switch mode power supply L901 / CR901 and C934. See Fig 6.1
for basic operation.
•
V1 supplies the DSC bus drivers, negative voltage regulators and MAGIC. V1 is
created from GCAP II Pin A6 and can be measured on C906.
B+
LX
Output
Fig 6.1
The basic circuit operation for the Boost circuit is as follows the LX signal (GCAP II
Pin B10) allows a path for B+ to charge the capacitor, when the switch is on, the
capacitor then discharges through the inductor (switch off), setting up an electric
field. The field then collapses setting up a back EMF to charge the capacitor, and so
on and so on. The back EMF created by the inductor is greater than B+ with the +ve
half of the cycle passing through the diode to charge a capacitor from where the
V_BOOST voltage is taken. The frequency of the switching signal LX decides the
duty cycle of the output wave and therefore the resultant voltage. V_BOOST is fed
back into the GCAP.
On initial power up the LX signal is not always immediately correct in frequency,
therefore the duty cycle of the B+ signal is incorrect which can lead to the switch
mode power supply creating huge current problems. To prevent this Q9808 is placed
with Q902 as a protection circuit.

A008 / A6188+ – Circuit Description
As excess current is drawn through B+ towards L901 through Q9808 source, Pin 4.
Q902 base will go low forcing its collector high. This high on Pin 3 Gate of Q9808
will switch off Q9808, therefore preventing B+ to the power supply, until LX is
stable.
• V2 – Programmed to 2.775V, available whenever the radio is on and supplies most of
the logic side of the board. V2 is supplied out of GCAP II Pin J2 and can be
measured on either C923 or C924.
• V3 – Programmed to 2.003V to support the Whitecap, but does support the normal
2.75V logic output from the Whitecap, it originates from GCAP II Pin B5 and can be
measured on C926 or C927.
• VSIM1 – Used to support either 3V or 5V SIM cards. Will dynamically be set to 3V
upon power up, but if the card cannot be read then the SIM card is powered down and
an attempt to read the card at 5V is tried. VSIM1 can be measured on C928 and is
distributed from GCAP II Pin C6 (For further information, see SIM Card Operation).
• VREF – Programmed as V2 i.e. 2.775 and provides a reference voltage for the
MAGIC IC, distributed from GCAP II Pin G9 and can be measured on C939.
• -5V – Used to drive TX Biasing, produced from LS_V1 and –5V_EN through U901
• SR_VCC – Power Cut Circuit - Used to buffer the SRAM U702 voltage with a built
in soft reset within the unit’s software. The reason for this is to protect the user from
any accidental loss of power up to 0.5 seconds i.e. If the unit is knocked, causing a
slight battery contact bounce, the SR_VCC will, to the user, keep the unit running
normally, whilst internally the unit resets itself. During this loss of power the unit
takes it’s power from a the RTC BATT. SR_VCC is created from a buffered V2
using R9922
• V1_SW – See Deep Sleep Mode
4) Once the power source has been selected to power the phone on the PWR_SW must
be toggled low. This can be done by pressing the Power Key to create PWR_SW,
which is supported by ON+ (GCAP II Pin C8), or inserting an external power source
into the Accessory Connector J600. Either way will drive Pin G5 ON2+ low

6) 13 MHz clock. On Power Up there are 2 different reference clocks produced.
Initially, as soon as power is applied to the MAGIC IC the crystal, Y200, supported
by the CRYSTAL_BASE (MAGIC Pin E1) will emit a 26MHz signal to the
MAGIC IC, which will internally be divided by 2 to give our external 13MHz clock.
This is then fed out of the MAGIC on Pin J6 (CLK_OUT) and distributed to
Whitecap Pin H10 (CLKIN), then from Whitecap to GCAP II Pin F5 as
GCAP_CLK. At the same time the 13MHz Varactor Diode CR248 is producing an
output. This output is controlled in the following way: The 26MHz from Y230 is
divided down to 200 kHz and fed to a phase comparator within the MAGIC. The
13MHz from CR230 is also divided down and fed in to the phase comparator, the
difference in phase produces an error voltage that is fed onto the cathode of the
Varactor CR230. Which regulates the output to a stable 13MHz clock. Once the
software is running and the logic side of the board has successfully powered up, the
CLK_SELECT signal from Whitecap Pin 1 is fed to MAGIC Pin G6. This in turn

Logic: SIM Card Interface
1) Once powered up, the SIM card is interrogated. The SIM interface is part of the
Whitecap U800 and it supports both ‘synchronous’ (Prepay card) and asynchronous,
serial data transmission, though the A008 is programmed only for asynchronous.
VSIM1 (SIM_VCC) is originally programmed to 3V but if the card is 5V then the
SIM card will be powered down and VSIM1 will be reprogrammed to 5V The
Whitecap interprets that the card is 5V if after programming with 3V, it cannot read
any data from the card. The signal levels for in and out of the SIM are now required
to be level shifted within GCAP II U900 to 3V these signals are:
• Reset (Whitecap Pin E9 – RST0) in to GCAP II Pin E9 – LS1_IN_TG1A. This
signal is then level shifted to the required voltage and fed out to SIM Contacts J900
Pin 4 from Pin J7 - LS1_OUT_TG1A.
• Clock: This is a 3.25MHz signal from Whitecap – CLK0 Pin E7 to GCAP II Pin G6
– LS2_IN. This signal is then level shifted to the required voltage and fed out to SIM
Contacts J900 Pin 6 from Pin F6 – LS2_OUT.
• SIM I/O – Data transmission to and from SIM card; for TX, from SIM card contact
SIM I/O Pin 5 through to GCAP II Pin J8 SIM I/O. Through level shifter to desired
voltage and out through Pin K10 (LS3_TX_PA_B+) to Whitecap Pin F3 DAT0_TX.
For RX data from Whitecap Pin B5 DATA0_RX to GCAP II, Pin H8 – LS3_RX
where the signal is level shifted to desired voltage and outputted on Pin J8 SIM I/O
to SIM contacts Pin 5 SIM I/O.
• SIM_PD – This signal is provided by the signal THERM (Batt Contact J610), or by
BATT+. If there are no batteries present then the unit will display ‘Insert Battery’. If
batteries are present but the SIM card is either not inserted or faulty ‘! NO SIM
CARD ‘ will be displayed. The reason behind this is to prevent the extra cost of a

1) The charging operation is as follows:
2) After a charger has been detected MAN_TEST_AD, the Whitecap U700 will
communicate with the device via DSC_EN.
3) EXT B+ is fed in from Accessory Connector J600 Pin 14 to the source of Q901,
controlled by U9819,(these components are placed purely for high voltage
protection), this voltage will then be passed back to the source of Q932, where the
line MOBPORTB detects the presence of EXT B+. The current is sensed through
R932 Current Sense Resistor, the voltage drop over it is sent to GCAP II Pin D9
I_SENSE, this is used to evaluate the charging current.
4) The charging current is then passed through CR932 to charge BATT +. The charge
current is restricted by the signal CHRGC – GCAP II Pin E8, this opens the gate of
Q635. CHRGC is programmed during charger phasing.
5) CHRG_EN Whitecap Pin 1, biases Q634 On or Off
Logic: Deep Sleep Mode
1) Deep sleep mode is there to provide a facility to save battery life by intermittently
shutting off part of the PCB. This is achieved in the following way. The signal
STDBY is generated from Whitecap Pin F1, and from here the signal is then passed
onto Q960 and Q921. This has the effect respectively of:
2) Grounding VREF which makes MAGIC inoperable
3) Grounding V2 This switches off MAGIC, and inhibits the Transmit path through
RF_V2
4) Also the signal is passed through a standby delay using the logic gate U9820 and
diode CR701 these provide a short delay between the de-activation of V2 and VREF
and the activation of LS_V1. Which will support the Down-link lines during sleep
mode.
5) The shutdown is only for a fraction of a second and during that time the GCAP Clock
supports the logic side of the unit. The GCAP clock is generated by Y900, which
generates a 32.768MHz clock. This clock is output from Whitecap Pin C7 and fed
directly to Whitecap Pin P4. The clock is always monitored by Whitecap and should
it fail, the unit will no longer go into deep sleep mode.

Logic: Keypad Operation
1) The keypad works as a matrix supported by V2. The signals inform the Whitecap
upon a key press by dropping the signal ‘low’. There are only 6 ‘hard’ keys, these are:
PAGE UP – KBR0
PAGE DOWN – KBR1
HOME – KBC0
POWER – PWR_SW
VA – KBC3
JOG DIAL – KBR2 / KBR3 for clockwise operation

Each row and column, is in effect a long imaginary resistor with a +ve voltage at one end
and a –ve or Grounded voltage level at the other. We can imagine that if these resistors
could be overlapped then we can create a comprehensive resistor matrix. It is this matrix
that provides us with the information of where the pen is placed on the touch screen. See

2) Power Lines these consist of the following: These are all created in the LCD Module
VD1 – 3.3V to supply logic circuit of LCD Driver
VD2 – 3.0V to segment driver
VM – 1.5V to for comparator of segment driver
Vdd - +ve LCD Drive Voltage
Vcc – Internal Logic voltage of Com Driver IC
Vss – -ve LCD Driver Voltage
3) Contrast control is again controlled from within the LCD module using a resistive
potential divider with the average room temperature contrast voltage being 12.5V.
4) The Data bus is a 4-line bus that is used to transfer pixel information to the LCD.
They are D0– D3. These lines connect between Dragon Ball U2000 Pins J10, M9, L9
& K9 and J9805 Pins 6,7,8,9 respectively.
5) The EL panel within the LCD requires a LCD AC voltage to correctly orientate the
liquid crystal. This is provide using a DC- AC Converter U9824. The DC to AC
converter samples the DC input before separating it into small elements that will
make up a sinusoidal waveform, this waveform is then stepped up to the appropriate
voltage using a transformer (L9800). The input is controlled by the signal backlight
and supported by PDA_VCC the resultant output will be a 100V amplitude sine
wave, EL+ see Fig 3

8) The analogue signal is fed from the LCD PCB as RIGHT / TOP / LEFT /
BOTTOM on J9805 Pins 1,2, 3 & 4 respectively and is fed to the ADC converter on
Pins 2, 3,4& 5. This data is then relayed to and from Dragon Ball on SPM_TXD and
SPM_RXD. The ADC is supported by PDA_VCC.
Logic: Communication
1) There are several ways by which the A008 can transmit and receive data; these are as
follows.
• Communication between the Whitecap and the Dragon ball, is carried on 6 lines,
these are U_CTS / U_RTX / URXD / UTXD / WD_INT* & DW_INT*.
• When W/CAP need to send data to Dragon ball, it will send an interrupt signal to
Dragon ball through WD_INT*. Dragon ball will response by clear U_CTS, then
data will be send to Dragon ball over the UART port. If Dragon ball need to send
data to W/CAP, it will send an interrupt to W/CAP through DW_INT*. The
communication is the same.
2) Communication between Whitecap and GCAP uses the following lines of
communication – DR2 / DX2 / MQSPI_CLK2 / MQSPI – CS0
• Where DR2 is data transfer from GCAP to Whitecap
• Where DX2 is data transfer from Whitecap to GCAP
• MQSPI_CLK2 is the data transfer clock
• MQSPI_CS0 is the select line for DR2 / DX2
3) For programming i.e. flashing the phone, we use the flow matrix consisting of U9821
/ U9822 and U2601. Basic function being.
• U9822 and U9821 are inverter and non inverting devices respectively
• PB2 (Whitecap Pin L2) is sent to the input of U9822 and also output as A to
U9821is used to decide whether information is sent from External Connector to
Whitecap or to Dragon Ball
• The signals CTS2* and RTS2* (Dragon Ball Pins F4 and F3) control data flow
and data can either be sent from either processor to External connector on the

4) IrDA – The IrDA transceiver module is U9812. The IrDA data takes the form of an
SIP (Serial Infrared Pulse) with SD_IrDA being an active high signal that turns the
LED on. The received signal IrDA RXD is always a pulsed, active low 2.4µs pulse,
and a low will light the LED. The data for TX is sent to IRDA_TXD U9812 Pin 7
from Dragon Ball as TXD2 Pin E4. For IRDA_RXD, information received is passed
from U9812 to Dragon Ball as RXD2 Pin E3
