UEM
Introduction to UEM
UEM is the Universal Energy Management IC for digital hand portable phones. In addition to energy management, it performs all the base band’s mixed-signal functions.
Most UEM pins have 2kV ESD protection, and those signals considered to be more easily
exposed to ESD, have 8kV protection within the UEM. These kinds of signals are (1) all
audio signals, (2) headset signals, (3) BSI, (4) Btemp, (5) Fbus and (6) Mbus signals.

System Module PAMS Technical Documentation
Regulators
The UEM has six regulators for baseband power supplies and seven regulators for RF
power supplies. The VR1 regulator has two outputs: (1) VR1a and (2) VR1b. In addition to
these, there are two current generators - IPA1 and IPA2 - for biasing purposes.
A bypass capacitor (1uF) is required for each regulator output to ensure stability.
Reference voltages for regulat ors require exter nal 1uF capacitors. Vref25RF is the refer-
ence voltage for the VR2 regulator, Vref25BB is the reference voltage for the VANA,
VFLASH1, VFLASH2, VR1 regulators, Vref278 is the re ference voltage for the VR3, VR4,
VR5, VR6, VR7 regulators, and VrefRF01 is the reference voltage for the VIO, VCORE regulators and for the radio frequency (RF).

The VANA regulator supplies the baseband’s (BB) internal and external analog cir cuitry.
It is disabled in the Sleep mode.
The Vflash1 regulator supplie s the LCD, the IR-module and the digital parts of th e UEM
and Safari asic. It is enabled during startup an d goes into the low Iq-mode when in the
Sleep mode.
The VIO regulator supplies both the e xternal and internal logic circuit ries. It is used by
the LCD, flash, bluetooth and UPP. The regulator goes into the low Iq-mode when in the
Sleep mode.
The VCORE regulator supplies the DSP and the core part of the UPP. The voltage is programmable and the startup default is 1.5V. The regulator goes into the low Iq-mode
when in the Sleep mode.
The VSIM regulator supplies the SIM card. NOT USED IN NPC-1.
Page 12 ãNokia Corporation Issue 1 10/01
NPC-1
PAMS Technical Documentation System Module
The VR1 regulator uses tw o LDOs and a charge pump. The charge pump requires one
external 1uF capacitor in the Vpump pin and a 220nF flying capacitor between the CCP
and CCN pins. In practice, the 220nF flying capacitor is f ormed by 2 x 100nF capacitors
that are parallel to each other. The VR1 regulator is used by the Safari RF ASIC.
The VR2 regulator is used to supply the (1) external RF parts, (2) lower band up converter, (3) TX power detector module and (4) Safari. In light load situatio ns, the VR2 regulator can be set to the low Iq-mode.
The VR3 regulator supplies the VCTCXO and Safari in the RF. It is always enabled when
the UEM is active. When the UEM is in the Sleep mode, the VR3 is disabled.
The VR4 regulator supplies the RX frontends (LNA and RX mixers).
The VR5 regulator supplies the lower band PA. In light load situations, the VR5 regulator
can be set to the low Iq-mode.
The VR6 regulator supplies the higher band PA and TX amplifier. In light load situations,
the VR6 regulator can be set to the low Iq-mode.
The VR7 regulator supplies the VCO and Safari. In light load situations, the VR7 regulator
can be set to the low Iq-mode.
The IPA1 and IPA2 are programmable current generators. A 27kW/1%/100ppm external
resistor is used to improve the accuracy of the output current. The IPA1 is used by the
lower PA band and IPA2 is used by the higher PA band.
RF Interface
The interface between the baseband and the RF section is also handled by the UEM. It
provides A/D and D/A conversion of the in-pha se and quadrature receive and transmit
signal paths. It also provides A/D and D/ A conve rsions of receiv ed and transmitte d audio
signals to and from the UI section. The UEM supplies the analog AFC signal to the RF section, according to the UPP DSP digital control.
Charging Control
The CHACON block of the UEM asics controls charging. The needed functions for the
charging controls are the (1) pwm-controlled battery charging switch, (2) charger-monitoring circuitry, (3) battery voltage monitori ng circuitry and (4) RTC supply circuitry for
backup battery charging (Not used in NPC-1). In addition to these, external component s
are needed for EMC protection of the charger input to the baseband module.
Digital Interface
Data transmission between the U EM and the UPP is impleme nted using two seri al connections, DBUS (programmable clock) for DSP and CBUS (1.0MHz GSM and 1.08MHz
TDMA) for MCU. The UEM is a dual voltage circuit: the digital parts are run from 1.8V
and the analog parts are run from 2.78V. The Vbat (3,6V) voltage regulators's input is
also used.

Audio Codec
The baseband supports two external microphone input ar eas and one external ea rphone
output. The input can be taken from an internal microphone, a headset microphone or
from an external microphone signal source through a headset connector. The output for
the internal earpiece is a dual-ended type output, and the dif ferential output is capable
of driving 4Vpp to the earpiece with a 60 dB minimum signal as the total distortion ratio.
The input and output signal source se lection and gain control is performed inside the
UEM Asic, according to the c ontrol messages from the UPP. A buzzer a nd an external
vibra alert control signal are gener ated by the UEM with separate PWM outputs.
UI Drivers
There is a single output driver for the buzzer, vibra, display and keyboard l eds an d the IR
in the side of the UEM. These generate PWM square wave for the various devices.
IR interface
The IR interface is designed and implemented into th e UEM. The low frequency mode of
the IR module covers speeds up to 115.2 kbit/s. The device (Vis hay) tr ansc eiv ers inte gra te
a sensitive receiver and a built-in power driver. The combination of a thin, long resistive
and inductive wiring should be avoided. The input (Txd, SD/M ode) and the output Rxd
should be directly coupled to the I/O circuit. The VBAT regulator supplies the power to
transmit the led and serial resistor limits’ current. Upon rece ivi ng infra red data to IR led,
it goes straight to the UEM via the RXD line . The Vflash1 is the power supply f or the IR
module, except for transmission.The IR module has one control pin to control the shut
down. The control lever shifter is used to change the proper voltage for shutdown to the
IR module from the UPP.
AD Converters
The UEM is equipped with a 11-channel analog to digital converter. Some AD converter
channels (LS, KEYB1-2) are not used in NPC-1. The AD converters are calibrated in the
production line.
UPP
Introduction
NPC-1 uses the UPPv4M ASIC. The RAM size is 4M. The processor architecture consists of
both the DSP and the MCU processors.
Blocks
The UPP is internally partitioned into two main parts: (1) the Brain and (2) the Body.
1 The Processor and Memory System (that is, the Processor cores, Mega-cells,
internal memories, perip herals and external memory inter face) is known as the
Brain.
The Brain consists of the following blocks: (1) the DSP Subsystem (DSPSS), (2) the
MCU Subsystem (MCUSS), (3) the emulation control EMUCtl, (4) the program/
data RAM PDRAM and (5) the Brain Peripherals–subsystem (BrainPer).

PAMS Technical Documentation System Module
2 The NMP custom cellular logic functions are known as the Body.
The Body contains interfaces and functions needed fo r interfacing other baseband and RF parts. The body consists of, fo r example, the following sub-blocks:
(1) MFI, (2) SCU, (3) CTSI , (4) RxModem, ( 5) Acc IF, (6) UIF, (7) C oder, (8) BodyIF, (9)
PUP.
Flash Memory
Introduction
The NPC-1 transceiver uses a 32 Mbit f lash as its external memory. The VIO regulator is
used as a power supply for normal in-system op eration. An accelerated program/erase
operation can be obtained by supplying Vpp of 12 volt to the flash device.
The device has two read modes: asynchronous and burst. The Burst read mode is utilized
in NPC-1, except for the start-up, when the asynchronous read mode is used for a short
time.
User Interface Hardware
LCD
Introduction
NPC-1 uses a black & white GD46 84x48 full dot matrix graphical display. There are two
suppliers for this LCD: Seiko Epson and P hilips. The LCD module includes the LCD glass,
the LCD COG-driver, an elastomer connector and a metal frame. The LCD module is
included in the lightguide assembly module.
Interface
The LCD is controlled by the UI SW and the control signals are from the UPP asic. The VIO
and Vflash1 regulators supply the LCD with power.
The LCD has an internal voltage booster and a booster capacitor is required between
Vout and GND.
Pin 3 (Vss9) is the LCD driver’s ground and Pin 9 (GND) is used to ground the metal
frame.
Keyboard
Introduction
The NPC-1 keyboar d styl e fol lows the Nokia Jack style , withou t side keys for vol ume co ntrol. The PWR key is integrated so that it is part of the IR window an d located on top of
the phone.
