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.

Temperature Conditions

Specifications are met within range of -10...+55 deg. C ambient temperature Storage temperature range -40...+70 deg. C

Humidity

Relative humidity range is 5... 95%. This module is not protected against water. Condensated or splashed water might cause malfunction momentary. Long term wetness will cause permanent damage.

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 Interface CCS 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.
