Introduction
Electrical Modules
The system module AK4 consists of Radio Frequency (RF) and baseband (BB). User Interface (UI) contains display, keyboard, IR link, vibra, HF/HS connector and audio parts.
FM radio is located on the main PWB AK4.
The electrical part of the keyboard is located in separate UI PWB named KU4. KU4 is connected to radio PWB through spring connectors.
The Baseband blocks provide the MCU, DSP, external memory interface and digital control functions in the UPP ASIC. Power supply circuitry, charging, audio processing and RF
control hard ware are in the UEM ASIC.
The purpose of the RF block is to receive and demodulate the radio frequency signal from
the base station and to transmit a modulated RF signal to the base station.
The UI module is described in a dedicated section of the manual.

System Module
The System module (or Engine) consists of Baseband and RF sub-modules, each described
below.
Baseband Module
Main functionality of the baseband is implemented into two ASICs: UPP (Universal Phone
Processor) and UEM (Universal Energy Management).
UPP ASIC provides the MCU, DSP, external memory interface and digital control functions.
UEM ASIC contains power supply circuitry, charging, audio processing and RF control
hardware.
The baseband architecture supports a power saving function called "sleep mode". This
sleep mode shuts off the VCTCXO, which is used as system clock source for both RF and
baseband. During the sleep mode the system runs from a 32 kHz crystal. The phone is
waken up by a timer running from this 32 kHz clock supply. The sleep time is determined
by net work parameters. Sleep mode is entered when both the MCU and the DSP are in
standby mode and the normal VCTCXO clock is switched off.
NPM-6/6X supports both three and two wire type of Nokia chargers. Three wire chargers
are treated like two wire ones. There is not separate PWM output for controlling charger
but it is connected to GND inside the bottom connector. Charging is controlled by UEM
ASIC (Universal Energy Management) and EM SW running in the UPP (Universal Phone
Processor).
BL-4C Li-ion rechargeable battery is used as main power source for NPM-6/6X. BL-4C
has a capacity of 720 mAh.

Technical Summary
Baseband of the NPM-6/6X is running from power rails 2.8V analog voltage and 1.8V I/O
voltage. UPP core voltages can be lowered down to 1.0V, 1.3V and 1.5V. UEM includes 6
linear LDO (low drop-out) regulator for baseband and 7 regulator for RF. It also includes
4 current sources for biasing purposes and internal usage. UEM also includes SIM interface which has supports both 1.8V and 3V SIM cards.
A real time clock function is integrated into the UEM, which utilizes the same 32kHz
clock supply as the sleep clock. A backup power supply is provided for the RTC-battery,
which keeps the real time clock running when the main battery is removed. The backup
power supply is a rechargeable surface mounted Li-Ion battery. The backup time with the
battery is 30 minutes minimum.
The interface between the baseband and the RF section is mainly handled by the UEM
ASIC. The UEM provides A/D and D/A conversion of the in-phase and quadrature receive
and transmit signal paths and also A/D and D/A conversions of received and transmitted
audio signals to and from the user interface. The UEM supplies the analog TXC and AFC
signals to RF section according to the UPP DSP digital control.

NPM-6/6X
System Module and User InterfaceCCS Technical Documentation
Data transmission between the UEM and the UPP is implemented using two serial busses, DBUS for DSP and CBUS for MCU. There are also separate signals for PDM coded
audio. Digital speech processing is handled by the DSP inside UPP ASIC.
The UEM is a dual voltage circuit, the digital parts are running from the baseband supply
1.8V and the analog parts are running from the analog supply 2.78V also VBAT is directly
used.
The baseband supports both internal and external microphone inputs and speaker outputs. Input and output signal source selection and gain control is performed by the UEM
according to control messages from the UPP. Keypad tones, DTMF, and other audio tones
are generated and encoded by the UPP and transmitted to the UEM for decoding. An
external vibra alert control signals are generated by the UEM with separate PWM outputs.
NPM-6/6X has two serial control interfaces: FBUS and MBUS. FBUS can be accessed
through a test pad and the System Connector as described later. The MBUS can be
accessed through the production test pattern as described in section MBUS Interface.
Note! NPM-6 uses 64Mbit flash memory and external 4MBit SRAM memory. NPM-6X uses
COMBO memory including 64MBit flash memory and 4Mbit SRAM.
EMC shielding is implemented using a metallized plastic frame. On the other side, the
engine is shielded with PWB grounding.
