Nokia Customer Care 6015/6015i/6016i/6019i (RH-55), 6012 (RM-20) Troubleshooting - Baseband Figure 3: Power up Power Up - Power Key When the power key is pressed, the UEM enters the power up sequence. Pressing the power key causes the PWRONX pin on the UEM to be grounded. The UEM PWRONX signal is not part of the keypad matrix. The power key is only connected to the UEM, which means that when pressing the power key, an interrupt is generated to the UPP that starts the MCU.
6015/6015i/6016i/6019i (RH-55), 6012 (RM-20) Troubleshooting - Baseband Nokia Customer Care forces the VCHAR input to rise above the charger detection threshold (VCHDET+) and by detection charging is started. The UEM generates 100 mA constant output current from the connected charger's output voltage. The battery’s voltage rises as it charges, and when the VBAT voltage level is detected to be higher than the master reset threshold limit (VMSTR+), the START_UP charge is terminated.
Nokia Customer Care 6015/6015i/6016i/6019i (RH-55), 6012 (RM-20) Troubleshooting - Baseband In sleep mode, the VCTCXO (19.2 MHz Clk) is shut down and the 32 kHz sleep clock oscillator is used as a reference clock for the baseband. The average current consumption of the phone can vary depending mainly on the SW state. However, the average consumption is about 6 mA in slot cycle 0.
6015/6015i/6016i/6019i (RH-55), 6012 (RM-20) Troubleshooting - Baseband • Vibra • Display and keyboard lights Nokia Customer Care The UEM is the heart of the power distribution to the phone, which includes all the voltage regulators. The UEM handles power-up hardware functions so the regulators are not powered and the power-up reset (PURX) is not released if the battery voltage is less than 3 V.
Nokia Customer Care 6015/6015i/6016i/6019i (RH-55), 6012 (RM-20) Troubleshooting - Baseband Clock Distribution RFClk (19.2 MHz Analog) The baseband’s main clock signal is generated from the VCTCXO (G501). This 19.2 MHz clock signal is generated at the RF and fed to the UPP’s RFCLK pin and the GPS BB ASIC. Figure 4: 19.2 MHz analog RFConvClk (19.2 MHz digital) The UPP distributes the 19.

Nokia Customer Care 6015/6015i/6016i/6019i (RH-55), 6012 (RM-20) Troubleshooting - Baseband DBUS Clk Interface A 9.6 MHz clock signal is used for DBUS, which is used by the DSP to transfer data between the UEM and the UPP. Figure 7: 9.6 MHz DBUS clock signal The system clock can be stopped during sleep mode by disabling the VCTCXO power supply from the UEM regulator output (VR3) by turning off the controlled output signal SLEEPX from the UPP.
6015/6015i/6016i/6019i (RH-55), 6012 (RM-20) Troubleshooting - Baseband Nokia Customer Care SleepCLK (Digital) The UEM provides a 32 kHz sleep clock for internal use and to the UPP, where it is used for the sleep mode timing. Figure 8: 32 kHz digital sleep clock signal SleepCLK (Analog) When the system enters sleep mode or power off mode, the external 32 KHz crystal provides a reference to the UEM RTC circuit to turn on the phone during power off or sleep mode.
6015/6015i/6016i/6019i (RH-55), 6012 (RM-20) Troubleshooting - Baseband Nokia Customer Care Figure 9: 32 KHz analog sleep clock signal Flash Programming Connections to Baseband The Flash programming equipment is connected to the baseband using test pads for galvanic connection. The test pads are allocated in such a way that they can be accessed when the phone is assembled.
6015/6015i/6016i/6019i (RH-55), 6012 (RM-20) Troubleshooting - Baseband Nokia Customer Care input data from the flash prommer. If the timer expires without any data being received, the MCU continues the boot sequence. The MBUS signal from the UEM to the external connection is used as a clock during flash programming. This means that the flash programming clock is supplied to the UPP on the MBUSRX signal.

6015/6015i/6016i/6019i (RH-55), 6012 (RM-20) Troubleshooting - Baseband Nokia Customer Care Temperature and capacity information are needed for charge control. These resistors are connected to the BSI pins on the UEM. The phone has 100KΏ pull-up resistors for these lines so that they can be read by A/D inputs in the phone. Figure 13: BL-6C battery pack pin order Charging Circuitry The UEM ASIC controls charging depending on the charger being used and the battery size.
6015/6015i/6016i/6019i (RH-55), 6012 (RM-20) Troubleshooting - Baseband Nokia Customer Care The charger recognition is initiated when the EM SW receives a "charger connected" interrupt. The algorithm basically consists of the following three steps: 1. Check that the charger output (voltage and current) is within safety limits 2. Identify the charger as a 2-wire or 3-wire charger 3.
6015/6015i/6016i/6019i (RH-55), 6012 (RM-20) Troubleshooting - Baseband Nokia Customer Care to separate inputs at the UEM. Inputs for the microphone signals are differential types. Also, the MICB1 is used for MIC1, and MICB2 is used for both MIC2 and MIC3 (Universal Headset). The HF single-ended output from the UEM is sent to the input of the MIDI audio amplifier. VBAT supplies the voltage for driving the amplifier, which can be enabled or disabled by the UPP using GenIO (10).
