RM-431 BB Troubleshooting and Manual Tuning Guide Ambient Light Sensor troubleshooting and re-calibration Introduction to ALS troubleshooting and re-calibration The Ambient Light Sensor (ALS) consists of the following components: • Ambient Light Sensor (N1100). ALS is a digital I2C interface component that has two channels with different spectral sensitivities. When combined, the component responds to illuminance similar as human eye.
RM-431 BB Troubleshooting and Manual Tuning Guide 2. Scan product on Phoenix (CTRL+R) 3. Choose Testing→Display test. 4. Open the Lights tab, and check the Ambient light sensor check box. Click the Read button in order to get the reference ambient light value. Cover the sensor and click Read again. When covered, the luminance reading should be less than after clicking Read without covering the sensor. 5.
RM-431 BB Troubleshooting and Manual Tuning Guide ALS troubleshooting Troubleshooting flow Issue 1 COMPANY CONFIDENTIAL Copyright © 2009 Nokia. All rights reserved.
RM-431 BB Troubleshooting and Manual Tuning Guide Calibrating ALS Steps 1. Connect the phone to Phoenix, start the Phoenix software, and set the phone (e.g. on the table) so that the ambient light visible to ALS is stable. The light quide of the ALS is located on the upper part of the phone’s front cover, right next to the secondary camera. 2. Scan product on Phoenix (CTRL+R) 3. Choose Testing→Ambient Light Sensor Calibration. 4.
RM-431 BB Troubleshooting and Manual Tuning Guide 9. Use Phoenix (Testing→Display test→Lights tab) to verify the calibration by reading the luminance value for both the reference phone and calibrated phone. Note: Remember that the illuminance readings for the reference and calibrated phones must be done in the same ambient light conditions. If the illuminance values differ more than +- 10%, repeat the whole ALS calibration procedure. 10. To end the calibration, click Close.

RM-431 System Module Board and module connections Energy management Battery and charging BL-4CT battery The phone is powered by a 3-pole BL-4CT 860 mAh battery. The three poles are named VBAT, BSI and GND where the BSI line is used to recognize the battery capacity. This is done by means of an internal battery pull down resistor. Figure 35 Battery pin order Page 6 –8 COMPANY CONFIDENTIAL Copyright © 2009 Nokia. All rights reserved.
RM-431 System Module The battery temperature is estimated by measuring separate battery temperature NTC via the BTEMP line. This is located on the main PWB, at the place where the phone temperature is closest to the battery temperature. Battery connector The battery connector is a blade connector. It has three blades; • BSI (Battery size indicator) • GND (Ground) • VBAT (Battery voltage) The BSI line is used to recognize the battery capacity by a battery internal pull down resistor.
RM-431 System Module Power key and system power-up When the battery is placed in the phone, the power key circuits are energized. When the power key is pressed, the system boots up (if an adequate battery voltage is present). Power down can be initiated by pressing the power key again and the system is powered down with the aid of SW. The power key is connected to EM ASIC (N2200) via the PWRONX signal.
RM-431 System Module Power distibution Figure 36 Power distribution diagram Issue 1 COMPANY CONFIDENTIAL Copyright © 2009 Nokia. All rights reserved.
RM-431 System Module SIM interface The phone has a SIM (Subscriber Identification Module) interface including a SIM connector. The connector is only accessible when the battery is removed. The SIM interface consists of an internal interface between RAPU and EM ASIC (N2200), and an external interface between EM ASIC and SIM contacts. Figure 37 SIM interface The EM ASIC handles the detection of the SIM card. The detection method is based on the BSI line.
RM-431 System Module USB USB interface The phone has an interface for USB (Universal Serial Bus). USB is a differential serial bus that provides a wired connectivity between a PC and peripheral devices, as in this case a mobile phone. Figure 39 USB interface The phone supports USB 2.0 with High-Speed (480 Mbps). Hot swap is supported, which means that USB devices may be plugged in and out at any time. MicroUSB connector This phone is provided with a specific connector for microUSB.
RM-431 System Module User interface Display interface The following block diagram illustrates the display interface. Display backlight is provided directly by EM ASIC. Figure 41 Display interface Keyboard interface The following block diagram shows the keyboard interface. The keyboard interface is implemented with RAPU’s GENIOs. Keyboard GENIOs are protected from ESD with 10-channel ASIPs Z4404 and Z4405.
RM-431 System Module Figure 42 Keyboard interface Ambient light sensor (ALS) interface Ambient light sensor information is used to control keyboard and display brightness. • Keyboard backlight is turned OFF, when it is not needed. • Display brightness is dimmed, when environment lighting is dark.
RM-431 System Module WLAN interface The phone contains a WLAN transceiver, that provides a fully integrated wireless radio solution. The WLAN transceiver supports the IEEE 802.11 standards for low error rate data transfer between mobiles and WLAN networks. Data rates up to 54Mbps are possible in 802.11g mode of operation. WLAN shares the antenna with Bluetooth. The WLAN software is downloaded from RAPU when WLAN is turned on, over the dedicated SPI interface.
RM-431 System Module Figure 45 Camera interface Audio interface The following block diagram illustrates the audio interface of the phone: Issue 1 COMPANY CONFIDENTIAL Copyright © 2009 Nokia. All rights reserved.
RM-431 System Module Figure 46 Audio interface The digital microphone is connected directly to RAPU. Stereo output is provided by a separate stereo audio amplifier, that is connected to EM ASIC. The output from the stereo audio amplifier is fed to the AV connector. The earpiece is driven directly by a built-in amplifier included in EM ASIC. The stereo IHF speakers are driven directly by a built-in stereo amplifier included in EM ASIC.
RM-431 System Module Figure 47 Bluetooth interface The BTHFM module is powered by VBAT and the regulated voltage VIO. For audio applications the Bluetooth has a PCM data bus. In addition an UART (universal asynchronous receiver/transmitter) is used for data communication and controls. Bluetooth shares the antenna with WLAN. FM radio interface The FM radio system is controlled by RAPU via the I2C bus. EM ASIC delivers the needed voltages and the clock reference (32.768kHz SleepClk).
RM-431 System Module Figure 48 FM radio interface RF description Receiver (RX) An analogue signal is received by the phone's antenna. The signal is converted to a digital signal and is then transferred further to the baseband (e.g. to the earpiece). The receiver functions are implemented in the RF ASIC. Signals with different frequencies take different paths, therefore being handled by different components. The principle of GSM and WCDMA is the same.
RM-431 System Module Transmitter (TX) The digital baseband signal (e.g. from the microphone) is converted to an analogue signal, which is then amplified and transmitted from the antenna. The frequency of this signal can be tuned to match the bandwith of the system in use (e.g. GSM900). The transmitter functions are implemented in the RF ASIC. Even though the GSM and WCDMA signals are sent via different components, the principle of the transmission is the same.
