NPM-2NX System Module CCS Technical Documentation Transceiver NPM-2NX Introduction The NPM-2NX is a dual band radio transceiver unit for GAIT (AMPS/TDMA800/ TDMA1900/GSM1900) networks. It is a true 3 V transceiver with internal antenna and vibra. Mechanical construction resembles Nokia 61XX series and the same accessories can be used. External RF connector is included. An integrated Infrared link is located on the top of the phone.
NPM-2NX System Module CCS Technical Documentation Engine Module WG8 Introduction This section describes the baseband part of the NPM-2NX transceiver. The BB architecture is similar to the earlier BB generation. The major difference is the integration level. Core BB consists of 2 ASICs and flash memory. BB core technical specification The core part of NPM-2NX BB (figure below) consist of 2 ASICs, UEM and UPP, and flash memory. Following sections describe these parts.
NPM-2NX System Module CCS Technical Documentation to energy management it performs all the baseband mixed-signal functions. Most of UEM pins have 2kV ESD protection and those signals, which are considered to be exposed more easily to ESD, have 8kV protection inside UEM. Such signals are all audio signals, headset signals, BSI, Btemp, Fbus and Mbus signals. Blocks REGULATORS UEM has 6 regulators for BB power supplies and 7 regulators for RF power supplies. VR1 regulator has 2 outputs VR1a and VR1b.
NPM-2NX System Module CCS Technical Documentation VCORE regulator supplies DSP and Core part of UPP. Voltage is programmable and startup default is 1.5V. Regulator goes to low Iq-mode in sleep mode. VSIM regulator supplies SIM card. Voltage is programmable. Regulator goes in to low Iqmode in sleep mode. VR1 regulator uses two LDOs and a charge pump. Charge pump requires one external 1uF capacitor in Vpump pin and 220nF flying capacitor between pins CCP and CCN. VR1 regulator is used by Safari_GTE RF ASIC.
NPM-2NX System Module CCS Technical Documentation DIGITAL IF Data transmission between the UEM and the UPP is implemented using two serial connections, DBUS (programmable clock) for DSP and CBUS (1.0MHz GSM and 1.08MHz TDMA) for MCU. UEM is a dual voltage circuit, the digital parts are running from 1.8V and the analog parts are running from 2.78V. AUDIO CODEC The baseband supports two external microphone inputs and one external earphone output.
NPM-2NX System Module CCS Technical Documentation UPP Introduction NPM-2NX uses UPPv8M ASIC. The RAM size is 8M. The processor architecture consists of both DSP and MCU processors. Blocks UPP is internally partitioned into two main parts: The Processor and Memory System (i.e. Processor cores, Mega-cells, internal memories, peripherals and external memory interface) is known as the Brain.
NPM-2NX System Module CCS Technical Documentation is 0.5mm. UIHW LCD Introduction NPM-2NX uses black/white GD51 96*65 full dot matrix display with COG driver. One vendor - SEIKO SED15B0 - is used in NPM-2NX. Interface LCD data, clock, chip select and reset signals come from the UPP. The VIO voltage is supplied to a logic voltage pin and the FLASH1 voltage is used to supply power to the LCD. The LCD uses extra filtering capacitors to filter voltages.
NPM-2NX System Module CCS Technical Documentation key connects the PWONX of the UEM to the GND and creates an interruption. Side key detection is achieved by connecting the line to the ground when pressing the side key (volume up or down). The emifilter is the ESD and EMC protection. The matrix-based keyboard interface consists of a scan column I/O data register and a row of data register. In the keyboard scanning procedure, the MCU performs access to these registers to find out which key was pressed.
NPM-2NX System Module CCS Technical Documentation ters to find out which key was pressed. Scanning is an interrupt procedure, i.e., an interrupt is generated when key is pressed and then the MCU can start the scanning procedure. Side keys are also detected in the same way as other keys except that there is no metaldome, but the middle pin is directly connected to the ground. Table 2: Matrix of key detection lines S0 / P00 S1 / P01 S2 / P02 S3 / P03 S4 / P04 R0 / P10 Side key / Vol.
NPM-2NX System Module CCS Technical Documentation allel. Vibra Introduction Vibra is located to D-cover and is connected by spring connectors on the left bottom side of the engine. Vibra manufacturers for NPM-2NX are Namiki and Matsushita. Interfaces Vibra is controlled by PWM signal VIBRA from UEM. With this signal it is possible to control both frequency and pulse width of signal. Pulse width is used to control current when battery voltage changes.
NPM-2NX System Module CCS Technical Documentation Figure 5: SIM block UEM Technical information The SIM interface is split between UEM and UPP. This has been done in order to reduce the amount of interconnections on the SIM interface between the UPP and the UEM. The SIM interface control logic and UART is integrated into the UPP. The SIM interface startup and power down sequence, including timing and reset generation is implemented in UEM.
NPM-2NX System Module CCS Technical Documentation Interface The earpiece is driven directly by UEM (EARP and EARN). Both lines are ESD protected inside UEM (±8kV). The earpiece is connected on the PWB by spring connectors. Technical information The rated impedance of the earpiece is 32Ω and sensitivity at 1mW/1kHz is 103±3dB. The diameter of the earpiece is 13.2mm and the thickness is 2.7mm. For more detailed specification see data sheets under material code 5140067.
NPM-2NX System Module CCS Technical Documentation PWM signal which controls the frequency and pulse width of signal of the buzzer. The buzzer has spring contacts to PWB. Technical information Rated input voltage is 3.6V and resonance frequency is 2700Hz. The size of the buzzer is 11mm x 10.2mm x 2.2mm without a gasket. For more detailed specification see data sheets under material code 5140229. Battery Phone battery Introduction Li-Ion 1000mAh battery BLB-3 is used in NPM-2NX by default.
NPM-2NX System Module CCS Technical Documentation storage time. The voltage seen in the outer terminals is zero (or floating), and the battery is activated by connecting the charger. Battery has internal protection for overvoltage and overcurrent. Figure 7: BLB-3 Battery contacts (BLB-2 has the same interface) 4(GND) 3(BTEMP) 2(BSI) 1 (+) Technical information Local mode is entered by inserting 560 Ohm resistors to these lines.
NPM-2NX System Module CCS Technical Documentation Interface Interface is compatible with Nokia 61XX and 51XX products. An accessory is detected by the HeadInt and HookInt line which are connected to system connector. The HookInt line is used to activate or end a call (only in HDC-9P).
NPM-2NX System Module CCS Technical Documentation The transmit of the IR module goes as follow. Transmit is controlled by TXD line which comes from UPP. Between UPP and IR module there is UEM which makes lever-shifter from 1.8V to 2.78V. VBAT gives power supply to transmit led and serial resistor (R350) limits current. There is also filter capacitor (C351) on VBAT-line to give proper voltage. Receiving infrared data to IR led, it goes straight to UEM by RXD line.
NPM-2NX System Module CCS Technical Documentation The charger connection is implemented through the system connector. The system connector supports charging with both plug chargers and desktop stand chargers. The charger is 2-wire or 3-wire galvanic charger. Connecting a charger creates voltage on VCHAR input of the UEM. When VCHAR input voltage level is detected to rise above VCHDET+ threshold by CHACON charging starts. VCHARDET signal is generated to indicate the presence of the charger.

GND 7.MBUS Other test points Because BB ASICs and Flash memory are CSP components the visibility to BB signals is very poor. This makes measuring of most of the BB signals impossible. In order to debug BB at least in some level the most important signals can be accessed from 0.6mm test points.
NPM-2NX System Module CCS Technical Documentation BB component and control/IO line protection Keyboard lines ESD protection for keyboard signals is implemented by using Emifilter Z300 detection The distance from the A-cover to the PWB is made longer with the spikes in the keymat. PWB All edges are grounded from both sides of PWB and solder mask is opened from these areas. Target is that any ESD pulse faces ground area when entering the phone, for example between mechanics covers.
