Flash Programming

The Vbb supply on the engine is connected to the programming voltage input of the Flash ROM. This voltage can be used for re-programming in After Sales or in the field. The programming can be made via the buses provided in the bottom and IBI connectors. No external programming voltage source is needed. In the engine production, the programming voltage is routed via the panel contacts and is isolated from the Vbb by means of a resistor or a diode. Thus a higher voltage (e.g.12 V) can be used to...

Baseband architecture

Nokia Block Diagram

The system specific ASIC and the DSP are integrated into one ASIC, called the MAD2WDUhe ARM on the part is able to run at 26MHz, a PLL is included to double the frequency. Lead megamodule will contain 16KW of RAM and 80KW ROM, RAM version 112kW for R amp D . The base-band architecture supports a power saving function called sleep mode, which is 32KHz clock taking over from VCTCXO. The base-band is running from a 2.8V power rail, which is supplied by a power controlling ASIC CCONT . In the CCONT...

SIM related faults

The hardware of the SIM interface from MAD2 D301 to the SIM connector Xl60 can be tested without a SIM card. When the power is switched on and if the BSI line X120 is grounded by a resistor, all the used lines VSIM,DATA, RST, CLK rise to 3V and then 5V the phone will try this four times . Thus Insert SIM card faults can be foundwithout a SIM card. The fault information SIM card rejected means that the ATR message the first message is always sent from card to phone is sent from card to phone but...

EGSM Signal path

For easy error tracing it is important to know the signal path of the EGSM receiver. The components can be grouped into blocks and drawn as shown below. From the antenna-pad X901 the RF signal is lead to the RX TX switch Z900 via a mechanical switch, the antenna connector X900 . The RX TX switch is normally open to the two RX outlets GSM_Rx and PCS_Rx. If no control voltage is present at VC1 or VC2 the RX TX switch will work as a diplexer and EGSM signals pass to GSM_Rx and PCN signals to...

Display Information Contact Service

Nokia Contact Service Self Test

This fault means that software is able to run and thus the watchdog of CCONT N102 can be served. Selftest functions are executed when power is switched on and software is started to execute from flash. If any of the self tests is failed, the information Contact Service will be shown in the phone display. MCU selftests are divided into those executed while power up start up tests and the ones that can be executed with connected PC. The tests and included items are as fol-lows screen dump from...
