NPM-10 (3595) System Module CC Technical Documentation VBATLim1,2L,2H are designed with hysteresis. When the voltage rises above VBATLim1,2L,2H+ charging is stopped by turning charging switch OFF. No change in operational mode occurs. After voltage has decreased below VBATLim- charging restarts. If VBAT is detected to rise above the programmed limit, the output signal OVV is set to ‘1’ by CHACON. If charging current limit is reached, OVC output is set ‘1’ by CHACON.

Connecting a charger forces VCHAR input to rise above charger detection threshold, VCHDET+. By detection start-up charging is started. UEM generates 100 mA constant output current from the connected charger’s output voltage.
NPM-10 (3595) System Module CC Technical Documentation The monitored battery functions are battery voltage (VBATADC), battery type (BSI), and battery temperature (BTEMP) indication. The battery type is recognized through a resistive voltage divider. In the phone there is a 100 kOhm pull up resistor in the BSI line and the battery has a pull-down resistor in the same line. Depending on the battery type, the pull-down resistor value is changed.

NPM-10 (3595) System Module CC Technical Documentation Figure 4: DLIGHT View Color LCD The LCD is a CSTN 96x65 full dot matrix display with a color resolution of 12bit (4096) and a one-pixel border area around the content area so total active area is 98x67 pixels. The LCD cell is part of the complete Display Assembly, which includes metal frame, gasket, light guide, spring connector, reflector, speaker, and dome sheet. The figure below illustrates the complete overview of the LCD module SIM Interface.
NPM-10 (3595) System Module CC Technical Documentation Figure 5: Overview of LCD module SIM Interface SIM Interface The UEM contains the SIM interface logic level shifting. The SIM supports 3 V and 1.8 V SIMs. SIM supply voltage is selected by a register in the UEM. It is only allowed to change the SIM supply voltage when the SIM IF is initialized. The SIM power up/down sequence is generated in the UEM. This means that the UEM generates the RST signal to the SIM.
NPM-10 (3595) System Module CC Technical Documentation The SIM interface is located in the two ASICs: UPP and UEM. The SIM interface in the UEM contains power up/down, port gating, card detect, data receiving, ATR-counter, registers, and level-shifting buffers logic. The SIM interface is the electrical interface between the Subscriber Identity Module Card (SIM Card) and mobile phone (via the UEM device). The data communication between the card and the phone is asynchronous half-duplex.
NPM-10 (3595) System Module CC Technical Documentation Ringer A 16-mm speaker is used to generate alerting tones and melodies to indicate incoming calls, as well as used to generate game sound, keypress, and warning tones for the user. Alerting tones and MIDI melodies are generated by the speaker, which is controlled by a sine driven output from the UEM and an external amplifier. The speaker is electrically connected to the PWB by spring contacts (similar to that for the internal earpiece).
NPM-10 (3595) System Module CC Technical Documentation The BSI fixed resistor value indicates the type and default capacity of a battery; NTC resistor BTEMP measures the battery temperature. Temperature and capacity information are needed for charge control. These resistors are connected to the BSI and BTEMP pins of the battery connector. The P\phone has 100 kΩ pull-up resistors for these lines so that they can be read by A/D inputs in the phone.
NPM-10 (3595) System Module CC Technical Documentation Table 25: Truth Table for HookInt and HeadInt (Continued) Accessory HookInt HeadInt PPH-1 H H No accessory H L The HeadInt signal is used to detect when the accessory is connected. The HookInt signal is used to detect when the button of the headset is pressed. Note: Charging must be disabled during identification of PPH-1. Headset Detection Supported headsets are four-wire fully differential accessories.
NPM-10 (3595) System Module CC Technical Documentation PPH-1 Detection PPH-1 accessory uses a four-wire fully differential audio connection. The accessory is detected by the Headint signal when the plug is inserted. PPH-1 has two operating modes with internal and external microphone. These modes can be separated by reading the EAD value. Detection of the PPH-1 can be split into three main phases: 1. Micbias is set to high impedance state 2. HeadInt interrupt is detected 3. EAD reading is 2.0 V - 2.
NPM-10 (3595) System Module CC Technical Documentation Implementation The implemented concept, which is using three pads/connections between the phone and the accessory cover, is shown in the following figure.
NPM-10 (3595) System Module CC Technical Documentation The matrix detection requires that two lines are pulled low at the same time. The matrix contains 15 keys. The six individual keys are detected by simple high-to-low transition interrupt. When the key has been detected, all the keypad registers inside the UPP are reset and it is ready to receive a new interrupt.
NPM-10 (3595) System Module CC Technical Documentation The device supports reads and in-system erase, and program operations at Vcc=1.8 V (Voltage range 1.7 V -1.9 V). Flashing at production is supported at Vpp=12 V (for limited exposure length only). Test Interfaces Through MBUS or FBUS connections, the phone HW can be tested through the Phoenix service software.

NPM-10 (3595) System Module CC Technical Documentation Use of the regulators can be seen in the power distribution diagram. VrefRF01 is used as the reference voltages for the RX ADCs reference in Mjoelner. The regulators are connected to Mjoelner, either directly or through output loading networks. The individual regulator can be switched on/off through the serial data bus in order to reduce the power consumption. Table 30 lists the needed supply voltages.

NPM-10 (3595) System Module CC Technical Documentation PLL Synthesizer, Functional Description The frequency synthesis PLL, in conjunction with the VCO and 2/4 dividers, generates the LO signal for both RX and TX paths, locked to the VCXO (which itself is locked to the base station through the AFC). Input to the PLL is the differential VCO and the 26 MHz reference oscillator signals. The VCO signal is divided by a swallow counter consisting of a 64/65 dual modulus divider and NDIV/ADIV dividers.
NPM-10 (3595) System Module CC Technical Documentation Receiver The receiver is a dualband, direct-conversion, linear receiver. The received RF signal is routed from the antenna to the RX/TX switch. The RX/TX switch performs both the switching between receive – transmit routing of the antenna signals as well as the selection of the band to be used. The RX signal is routed from the RX/TX switch to the RX bandpass filter.
NPM-10 (3595) System Module CC Technical Documentation GPRS Requirements GPRS Dual Slot RX The power level transmitted by the base station will not be the same in all RX slots seen from the mobile phone. Each block interleaved on four time slots will be transmitted on the same level from the base station. In single RX slot operation, this means that four successive time slots will receive a signal on the same level if we ignore fading.
