Electrical Modules
The RH-23 has been split into two different parts. The System Module 1AQ consists of:
Baseband (BB) Engine, FM-radio, Vibra, IR link, Pop-Port system connector, hardware
accelerator for camera and Radio Frequency (RF) parts.
System module and upper block flex are connected together with a hinge flex 1BF via
40-pin board-to-board connectors.
The keyboard is located in separate UI PWB named 1BF. 1BF is connected to system module through a board-to-board connector.
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 hardware 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.

Baseband Module
Technical summary
Main functionality of the baseband is implemented into two ASICs: UPP (Universal Phone
Processor) and UEM (Universal Energy Management).
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 1.57V. RH-23 core voltage is 1.57V. UEM
includes 6 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. UEM also
includes SIM interface which supports both 1.8V and 3V SIM cards.
A real time clock function is integrated into the UEM. RTC 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 UEM ASIC handles the analog interface between the baseband and the RF section.
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. 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. 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.
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. RH-23 has a serial control interface: FBUS. FBUS can be accessed through a test
pad and the Pop-Port as described later. EMC shielding is implemented using metal cans.

Baseband functional description
Modes of operation
RH-23 baseband engine has six different functional modes:
1No supply
2Backup
3Acting Dead
4Active
Page 14Nokia Corporation.Issue 1 02/2004
Company confidential RH-23
CCS Technical DocumentationSystem Module and User Interface
5Sleep
6Charging
No Supply
In NO_SUPPLY mode, the phone has no supply voltage. This mode is due to disconnection
of main battery and backup battery or low battery voltage level in both of the batteries.
Phone is exiting from NO_SUPPLY mode when sufficient battery voltage level is detected.
Battery voltage can rise either by connecting a new battery with VBAT > VMSTR+ or by
connecting charger and charging the battery above VMSTR+.
Back_Up
In BACK_UP mode the backup battery has sufficient charge but the main battery can be
disconnected or empty (VBAT < VMSTR+ and VBACK > VBUCOFF). VRTC regulator is disabled
in BACK_UP mode. VRTC output is supplied without regulation from backup battery
(VBACK). All the other regulators are disabled in BACK_UP mode.
Acting Dead
If the phone is off when the charger is connected, the phone is powered on but enters a
state called ”Acting Dead”. To the user, the phone acts as if it was switched off. A battery-charging alert is given and/or a battery charging indication on the display is shown
to acknowledge the user that the battery is being charged.
Active
In the Active mode the phone is in normal operation, scanning for channels, listening to
a base station, transmitting and processing information. There are several sub-states in
the active mode depending on if the phone is in burst reception, burst transmission, if
DSP is working etc.
One of the sub-states of the active mode is FM radio on state. In that case, Audio Amplifier and FM radio are powered on. FM radio circuitry is controlled by the MCU and
32kHz-reference clock is generated in the UPP. VFLASH2 regulator is operating.
In Active mode the RF regulators are controlled by SW writing into UEM’s registers
wanted settings: VR1A can be enabled or disabled. VR2 can be enabled or disabled and
its output voltage can be programmed to be 2.78V or 3.3V. VR4 -VR7 can be enabled,
disabled, or forced into low quiescent current mode. VR3 is always enabled in Active
mode.
Sleep Mode
Sleep mode is entered when both MCU and DSP are in stand–by mode. Both processors
control sleep-mode. When SLEEPX signal ‘low’ is detected UEM enters SLEEP mode.
VCORE, VIO and VFLASH1 regulators are put into low quiescent current mode. All the RF
regulators are disabled in SLEEP. When SLEEPX signal ‘high’ is detected UEM enters
ACTIVE mode and all functions are activated.
