Introduction

Electrical modules

The system module 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.

The electrical part of the keyboard is located in separate UI PWB. It 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 UEMEK 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

Product NPL-4/5 is a DCT4 Active segment phone. There are two variants: An EGSM900 / GSM1800 / GSM1900 phone and a US variant with GSM850/1800/1900.

The HW has the following features:

• HSCSD, GPRS (MSC10) and EGPRS (MSC6)

• DCT4 engine with UPP8M v3.5 and UEMEk v1.1

• AMR and 16 MIDI tones

• 128/16 Mbit Psram Combo memory

• Passive display with 4k colours

• Battery BL-5B

• Pop-Port interface

• 5-way navigation key with select

• Electrical compass

• FCI on bottom cover

• VGA Camera

•Vibra

•IHF

•FM Radio

•IrDA

•Torch

• PTT key

•Sidekeys

The NPL-4/5 BB is based on the DCT4 engine and is compatible to the Pop-Port accessories. The DCT4/4.5 engine consists basically of two ASICs. The UEMEK (Enhanced Universal Energy Management) IC including voltage regulators, charge control and audio circuits, audio IFH amplifier from DCT4.5) and the UPP (Universal Phone Processor including MCU, DSP and RAM from DCT4).

Baseband 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. UEMEK includes 7 linear LDO (Low Drop-Out) regulator for baseband and 7 regulators for RF. It also includes 4 current sources for biasing purposes and internal usage. UEMEK also includes SIM interface

which has supports both 1.8V and 3V SIM cards. Note: 5V SIM cards are no longer sup-

ported by DCT-4 generation baseband.

A real time clock function is integrated into the UEMEK, 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.

A UEMEK ASIC handles the analog interface between the baseband and the RF section.

UEMEK 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 UEMEK supplies the analog TXC and AFC signals to RF section according to the UPP DSP digital control. Data transmission between the UEMEK 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.

NPL-4/5

System Module and User Interface Nokia Customer Care

UEMEK 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.

VBAT is directly used for Vibra, LED-driver, Audio amplifier and FCI (Functional Cover Interface).

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 network parameters. Sleep mode is entered when both the MCU and the DSP are in standby mode and the normal VCTCXO clock is switched off.

The baseband supports both internal and external microphone inputs and speaker outputs. UEMEK also includes third microphone input. This input is used for FM-radio. Input and output signal source selection and gain control is done by the UEMEK 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 UEMEK for decoding. An external vibra alert control signals are generated by the UEMEK with separate PWM outputs.

The NPL-4/5 uses D-class amplifier to amplifying IHF speaker audios. It gives more sound pressure from speaker and efficiency is in good level to improve thermal performance compared to AB-class.

VGA Camera is connected to baseband (UPP) through HW accelerator IC. The camera data bus is common with display bus. The HWA is taking care of camera control and it is compressing the pictures.

NPL-4/5 has 2-axes electrical compass. It is implemented with magnetoresistive sensor and MagIC ASIC.

NPL-4/5 has two serial control interfaces: FBUS and MBUS. FBUS and MBUS can be accessed through production test pattern and FBUS can be also accessed thought Tomahawk System Connector.

The FCI interface is located to front bottom side area of the phone. This means that only B-cover can be an active cover.

EMC shielding is implemented using a metal body profile, RF cans and PWB grounding. Some components are outside of shielding. Heat generated by the circuitry is conducted out via the PWB ground planes and by using buried vias between PWB layers.
