Hierarchy of Design

The difference between the three PCB layouts is only the position of the keys &

LEDs (and one less LED on the DU8 version) The DU8 has 20 main keys,

2 volume keys at the side of the flex and a power key in the upper right corner

of the flex. The DU9 has 20 main keys in a slightly different layout and the vol-

ume / power keys combined on one assembly.

The GU3E has one LED less than DU8. Volume and power keys are as in DU8.

Warnings and Restrictions

Limited Bending Ability: The flexible circuits are constructed from a lamination

of three layers of polyamide and two layers of copper tracks. The polyamide

has almost unlimited bending capability – but the copper tracks cannot be bent

to tight radii very often. At all times before the flexi circuit is installed into a

phone, bending of the circuit should be avoided if possible. If the flexi circuit

has already been installed into the phone, then care should be taken not to

continuously fold the flexi circuit out flat and then back to its resting position too

often.

Functional Description

The module is connected with 30 pin flex connector to the system board, 24 pin

connector to the LCD module and 6 pin connector to the SIM card.

The module includes following main blocks:

– keyboard – SIM interface – illumination – audio block – LCD Module interface

Keyboard Scanning

COL(0–4) are used as column lines in keyboard. UIF(0–5) are used as row

lines. They are also multiplexed with display driver control signals.

When a key is pressed the ASIC gets an interrupt from a row and the MCU

starts scanning. One column at a time is written to low and rows are used to

read which key it was. The power off detection is multiplexed with one row;

when all keys on the row seems to be pressed the ASIC knows that power key

is pressed. The power key is also connected to PSL+ to switch the power on.

06/97JR Technical Documentation

Row lines and UIF6 are used for display driver control. UIF(0–3) are used as 4

bit parallel data bus for the driver. UIF4 is used as read/write strobe, UIF5 to

select data or instruction register and UIF6 as enable strobe.

Keyboard and Display illumination

The keyboard illumination is achieved by using two transistors wired as simple

constant current sinks. Each transistor supplies eight leds. The bases of the

transistors are all wired together and supplied by emitter follower V40. The led

current is fixed by the values of R44 and R45 and the ratio of R51 to R52. The

current is about 5 mA/ each LED. Note that on DU9 flexis, the 17

from an additional transistor.

The display illumination operates in a similar way to the keyboard drivers, two

transistors are used to drive eight leds. The current in this case is defined by

the value of R46, R47 and the ratio of R51 to R52. It is about 10 mA/ each LED.

Audio Circuitry

The earpiece is routed directly via series resistors to connector X4. The ear-

piece is dynamic type. The impedance is 32 Ω and sensitivity 118 dB/1 V.

Microphone is of the electret type and needs a voltage supply for operation.

When MIC_ENA is low bias voltage is connected to the microphone via transis-

tor V8. V2 is wired as a switch for VA1, controlled by the microphone enable

line [MICENA]. VA1 is an analogue rail supplied by the PSL+ chip on the sys-

tem board. It is 4.65 V in magnitude. The sensitivity of the microphone is –62

dB (0 dB = 1V/µbar). C26 and C27 in the MIC nodes act as high pass filter with

pulldown resistors on the baseband side.–3 dB point is about 100Hz.

The buzzer is dynamic one and the impedance is 25 ohm. Buzzer is driven

from a two transistor switch which acts as a buffer for a CMOS output signal

applied at BUZZER. The ringing volume is controlled by pulse width modula-

tion.The diode V37 prevents damage to the transistor when switched off, ab-

sorbing the stored energy in the buzzer inductance and suppressing large posi-

tive going spikes on the transistor collectors.

Small value capacitors are fitted at critical points in the circuit to avoid problems

with rf interference. One is placed directly across the microphone (C15). V9 has

a cap to ground from each of its three terminals (C14, C17 and C21). There is

also capacitors in earphone nodes.

LCD Module Interface

The LCD module includes the LCD and the display driver. The driver TAB is

connected with heat seal connection to the LCD. The LCD is FSTN type. The

duty ratio is1/32 and the bias ratio 1/6.7. Viewing direction is 6 o‘clock.

The display driver is NJU6406–02 from JRC. It has internal clock oscillator and

negative voltage generator. It has 9600 bit character generator ROM and 64 * 8

bits character generator RAM. The display module is connected to the UIF

module with 24 pin soldered connection.

The display module contains an oscillator to generate a negative voltage re-

quired for operation. The oscillator frequency is fixed on the UIF module by the

resistance from pins 2 to 3 of X1, with the values of R6 and R16 shown, the fre-

quency is within 180 kHz to 370 kHz. The negative going pulses appear at pin 9

of X1 where they are smoothed by C1 to give a voltage which is nominally

equal but opposite to VL1.

For correct operation of the display, D.C. voltages between –VL1 and VL1 need

to be generated and fed back to the driver chip, at pins 4 to 8 inclusive (of X1).

The exact voltages depend on the relative values of the resistors R21, R37,

R38, R39, R40 and R33.

UIF MODULES DU8, DU9, GU3E

NHE–1/4 NHK–1/4 NHB–2

The display driver is connected to the radio module with a 4 bit data bus. Data

transfer is controlled with the following signals: R/W selects read or write opera-

tion (”0” = write, ”1” = read), Enable activates read/write operations and RS se-

lects the register (”0” : instruction register (writing) or busy flag (reading), ”1” :

data register).

SIM Interface

The SIM interface is the electrical interface between the smart card used in the

GSM and PCN applications and the MCU via the ASIC. Four signals are used

between the SIM card and the ASIC:SIMDATA, SIMCLK, SIMRESET and

VSIM. Serial data is transferred between the card and the ASIC, the clock fre-

quency is 3.25 MHz. When there is no data transfer between the SIM card and

the HP the clock can be reduced to 1.625 MHz. Some cards allow to stop the

clock in that mode. The ASIC also generates the reset for the card and the sup-

ply voltage VSIM.
