Baseband Module Introduction

This chapter describes the baseband module for the RM-8/RM-47/RM-48 program. The baseband module includes the baseband engine chipset, the UI components and acoustical parts of the transceiver.

The RM-8 is a hand-portable EGSM900/GSM1800/GSM1900 phone for the fashion segment. RM-47 ( EGSM900/GSM1800/GSM1900) and RM-48 (GSM850/GSM1800/GSM1900) are hand-portable phones for the classic segment. They all have the DCT4.5 generation baseband and RF circuitry. The key driver for these products is the implementation of EDGE, introducing true multimedia capability from WCDMA in GSM single mode.

RM-8/RM-47/RM-48 is equipped with the DCT4 connector, supporting most of the DCT4 accessories. The battery interface is relative new consisting of only 3 connections. Standard battery is BL-4C battery with 760mAh capacity.

ADC settings in the SW might shutdown the phone above this value.

During fast charging of an empty battery, the voltage might exceed this value. Voltages

between 4.20 and 4.60 might appear for a short while.

■ Temperature conditions

• Operational temperature range (all specifications met within this range): –5°C.. +55°C (stationary use)

• Functional temperature range (reduced performance): –30°C.. +70°C

• Storage temperature range: –30°C.. +85°C

Temperatures at –10°C, +25°C and +55°C are used for the cpk analysis.

The baseband module complies with the SPR4 Operating Conditions.

■ Humidity

Relative humidity range is 5...95%.

The BB module is not protected against water. Condensed or splashed water might cause malfunction. Any submerge of the phone will cause permanent damage. Long-term high humidity, with condensation, will cause permanent damage because of corrosion.

The baseband module complies with the SPR4 Operating Conditions.

■ Vibration

The baseband module complies with the SPR4 Operating Conditions.

■ ESD strength

Standard for electrostatic discharge is IEC 61000-4-2 and level 4 requirements are fulfilled.

The baseband module complies with the SPR4 Operating Conditions.

Technical Specifications

■ UEME

UEME is the Universal Energy Management Enhanced IC for digital hand portable phones. In addition to energy management, the UEME functionality performs all baseband mixed–signal functions.

The different states of the UEME are explained below.

No supply

In the NO_SUPPLY mode the UEME has no supply voltage (VBAT < VMSTR and VBACK<V_BUCOFF-). This mode is due to the fact, that both the main battery and the backup battery are either disconnected or both discharged to a low voltage level.

The UEME will recover from NO_SUPPLY into the RESET mode, if the VBAT voltage level rises above the VMSTR+ level, by either reconnecting the main battery or charging it to such level.

Backup

In the BACK_UP mode the main battery is either disconnected or has a low voltage level (VBAT < VMSTR- and VBACK > V_BUCOFF+).

The regulator VRTC that supplies the real time clock is disabled in the BACK_UP mode. Instead the unregulated backup battery voltage VBACK supplies the output of the VRTC. All other regulators are disabled and the phone has no functionality.

The UEME will recover from the BACK_UP mode into the RESET mode if VBAT rises above VMSTR+.

Power off

In order for the UEME to be in the PWR_OFF mode, it must have supply voltage (VBAT > VMSTR+).

The VRTC regulator is enabled and supplying the RTC within the UEME. The UEME will enter the RESET mode after a 20 ms delay whenever one of the below listed conditions is logically true:

• The power button is activated.

• Charger connection is detected.

• RTC alarm is detected.

The UEME will enter PWR_OFF from all other modes except NO_SUPPLY and BACK_UP if the internal watchdog elapses.

Reset

When the UEME enters the RESET mode from the PWR_OFF mode the watchdog is enabled. If the VBAT fails to rise above the power-up voltage level VCOFF+ (3.1 V), before the watchdog elapses, the UEME will enter the PWR_OFF mode. Otherwise, after a 200 ms delay the regulator VFLASH1 will be enabled and after an additional delay of 500 s, the regulators VANA, VIO, VCORE and VR3 will be enabled. All other regulators i.e. VFLASH2, VSIM, VR1, VR2 and VR4

RM-8/RM-47/RM-48

7 - System Module Nokia Customer Care

– VR7 are software controlled and disabled by default. After an additional delay of 20 ms, the UEME enters the PWR_ON mode.

Power on

In PWR_ON the UEME is fully functional in the sense that all internal circuits are powered up or can be by means of software. The UEME will enter the PWR_OFF mode if VBAT drops below VCOOF- for a period of time longer than 5 s. The UEME will furthermore enter the PWR_OFF mode if either of the watchdogs Operational State Machine (approx. 100 s), Security (32 sec.) or Power Key (4 sec.) elapses or if any of the regulators triggers the thermal protection circuitry.

Sleep

The UEME can be forced into the SLEEP mode by the Tiku by setting the input SLEEPX low for more than 60 s. This state is entered when the external Tiku activity is low (phone in sleep) and thereby lowering the internal current consumption of the UEME. The regulator VANA is disabled and VR1 – VR7 are either disabled or in low quiescent mode. From SLEEP the UEME enters PWR_ON if SLEEPX goes high, the PWR_OFF mode if watchdog elapses or the BACK_UP mode if VBAT drops below VMSTR-.

Protection mode

The UEME has two separate protection limits for over temperature conditions, one for the charging switch and one for the regulators. The temperature circuitry measures the onchip temperature. In case of charging over temperature, the circuit turns the charging switch off. In case of over temperature in any of the regulators, the UEME powers off.
