  • Page 3: Introduction

    MSM bus bridges support peripherals that do not have an AHB interface. The mobile terminal supports standard Nokia 2-wire and 3 wire chargers (AC-3, AC-4, DC-4). However, the 3-wire chargers are treated as 2-wire chargers. The pulse width modulation (PWM) controls signal for controlling the 3-wire charger is ignored.

    20ms and is sent to MSM. Resets are generated for the MSM’s internal MCU and its internal DSP, and MSM sends TCXO_ON (“TCXO_EN” pin in 1265 schematic) signal to PM to enable TCXO. After PON_RESET_N goes high, MSM holds PS_HOLD at low state for 200ms and then drives PS_HOLD to high state.
  • Page 6: Power Up

    When the power key is pressed, the PM enters the power-up sequence. Pressing the power key causes the KPD_PWR_N (PHONE_ON_N pin in 1265 schematic) pin to GND. The KPD_PWR_N signal is not part of the keypad matrix. The power key is only connected to the PM.

    There are several sub-states under the active mode. Depending on the mobile terminal’s current state, there are states such as burst reception, burst transmission, etc. Issue 1 04/2007 © 2007 Nokia Corporation Company Confidential Page 7...

    19.2 MHz +/-2ppm. The SLEEP_CLK provides a 32.768 kHz +/-20ppm clock source to drive the MSM controller into sleep mode. At this mode, most of the MSM is powered down and the TCXO is disabled. Issue 1 04/2007 © 2007 Nokia Corporation Company Confidential Page 9...

    The PM includes several clock circuits (Figure 4), whose outputs are used for general housekeeping, MSM and RF functions within the mobile terminal system. Figure 4: TCXO & SLEEP_XTAL Block Diagram Page 10 © 2007 Nokia Corporation Company Confidential Issue 1 04/2007...

    PM defaults to this SBI-controlled mode with the TCXO defaulted on. This assures the MSM will always have a clock available immediately at power-up even if TCXO_EN is low. TCXO waveform (19.2MHz +/-2ppm) Issue 1 04/2007 © 2007 Nokia Corporation Company Confidential Page 11...

  • Page 15: Charging Operation

    Charging Operation Battery The 1265 uses a Lithium-Ion cell battery with a capacity of 860 mAh. QSC6010 reads the resistor inside the battery pack on the BSI line to identify the battery size. Different charging algorithm will be used for different battery sizes. The resistors are connected to the BSI pin inside the battery connector.
  • Page 16: Charger Detection

    Baseband Description and Troubleshooting Charger Detection Connecting a charger creates a voltage on the VCHG (“VEXT_DC” pin in 1265 schematic) input of the PM. Charging starts when the PM detects the VCHG input voltage level above 3.3V (Min. working voltage of VCHG pin).
  • Page 17: Charge Control

    The baseband supports 2 microphone inputs and three receiver (earpiece)/ speaker outputs. MIC+ & MIC- inputs of 1265 schematic are used for the mobile terminal's internal microphone. JACK_MIC+ & JACK_MIC- input are used for headsets. Every microphone input can have either a differential or single-ended AC connection to the QSC6010 circuit.
  • Page 18: Display And Keyboard

    The mobile terminal uses a white and black LCD. The interface uses a parallel bus to transfer the Command/ Data between QSC6010 and LCD. The panel for 1265 is a 96x65dot matrix FSTN LCD module. It has a FSTN panel composed of 96 segments and 65 commons. The LCD interface uses parallel bus for controlled Command/ Data .

    The mobile terminal supports Nokia standard 2.5mm mono headset. The headset insertion to the mobile terminal is detected through pin 4 (HS_DET) of the headset Jack, J580. HS_DET (“JACK_SENSE” pin in 1265 schematic) is low when headset not inserted. It becomes high when headset is inserted.
