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 ex ternal analog circuitry. 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 external and internal l ogic circuitries. 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 D SP and the core part of the U PP. 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 NPW-1.

NPW-1
PAMS Technical Documentation System Module
The VR1 regulator uses two 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 gener ators. 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 NPW-1). In addition to these, external components 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.

There is a single output driver for the buzzer, vibra, display and keyboard LEDs and 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) transceivers integrate 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 receiving infrared data to IR LED, it goes straight to the UEM via the RXD line. The Vflash1 is the power supply for 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 NPW-1. The AD converters are calibrated in the production line.
UPP
Introduction
NPW-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).

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 NPW-1 transceiver uses a 32 Mbit flash as its e xte rnal memor y. 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 NPW-1, except for the start-up, when the asynchronous read mode is used for a short time.

LCD
Introduction
NPW-1 uses a black & white GD46 84x48 full dot matrix graphical display. There are two suppliers for this LCD: Seiko Epson and Philips. 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 NPW-1 keyboard style follows the Nokia Jack style, without side keys for volume control. The PWR key is integrated so that it is part of the IR window and located on top of the phone.
Figure 3: Placement of keys.
Power Key
All signals for the keyboard come from the UPP asic, except PWRONX line for the power key signal which is connect ed dir ectly to t he U EM. The pr essing o f the PWR k ey gro und s the PWRONX line and the UEM generate s an inter rupt to U OO, which is then re cognized as a PWR key press.
