NPC-1 System Module PAMS Technical Documentation Transceiver NPC-1 Introduction The NPC-1 is a single band transceiver unit designed for TDMA800 networks. The transceiver consists of the engine module (WS8) and the various assembly parts. The transceiver has a full graphic display and the user interface is based on a jack style UI with two soft keys. An internal antenna is used in the phone, and there is no connection to an external antenna.
PAMS Technical Documentation NPC-1 System Module Operational Modes Below is a list of the phone’s different operational modes: 1 Power Off mode 2 Normal Mode (include various Active and Idle states): • Analog Modes (800 MHz only): •Analog Control Channel, ACCH •Analog Voice Channel, AVCH • Digital Modes (800 MHz): •Control Channel, DCCH •Digital Voice Channel, S-DTCH •Digital Data Channel, D-DTCH 3 Sleep and OOR modes (both Analog and Digital) 4 Local mode 5 Test mode Environmental Specification
NPC-1 System Module PAMS Technical Documentation range. For example, the RX sensitivity requirement is 3dB lower over the –30 - +60 °C range.
NPC-1 System Module PAMS Technical Documentation Engine Module Baseband Module The core part of the transceiver’s baseband (figure 1) consists of 2 ASICs, the UEM and UPP, and flash memory. The following sections illustrate and explain these parts in detail. Figure 2: System Block Diagram (simple) PA supply RF Supplies BATTERY SAFARI RFIC CTRL RFCLK 19.
NPC-1 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 regulators require external 1uF capacitors.
PAMS Technical Documentation NPC-1 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 formed by 2 x 100nF capacitors that are parallel to each other. The VR1 regulator is used by the Safari RF ASIC.
NPC-1 System Module PAMS Technical Documentation Audio Codec The baseband supports two external microphone input areas and one external earphone 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 differential output is capable of driving 4Vpp to the earpiece with a 60 dB minimum signal as the total distortion ratio.
PAMS Technical Documentation 2 NPC-1 System Module The NMP custom cellular logic functions are known as the Body. The Body contains interfaces and functions needed for interfacing other baseband and RF parts. The body consists of, for example, the following sub-blocks: (1) MFI, (2) SCU, (3) CTSI, (4) RxModem, (5) AccIF, (6) UIF, (7) Coder, (8) BodyIF, (9) PUP. Flash Memory Introduction The NPC-1 transceiver uses a 32 Mbit flash as its external memory.
NPC-1 System Module PAMS Technical Documentation 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 connected directly to the UEM. The pressing of the PWR key grounds the PWRONX line and the UEM generates an interrupt to UOO, which is then recognized as a PWR key press.
NPC-1 System Module PAMS Technical Documentation Interfaces The display lights are controlled by a Dlight signal from the UEM. The Dlight output is the PWM signal, which is used to control the average current going through the LEDs. When the battery voltage changes, the new PWM value is written onto the PWM register. In this way, the brightness of the lights remains the same with all battery voltages within range. The frequency of the signal is fixed at 128Hz.
NPC-1 System Module PAMS Technical Documentation Audio HW Earpiece Introduction The Philips Speaker System 13mm speaker capsule is used in NPC-1. The speaker is a dynamic one. It is very sensitive and capable of producing relatively high sound pressure also at low frequencies. The speaker capsule and the mechanics around it together make the earpiece. Microphone Introduction The microphone is an electret microphone with an omnidirectional polar pattern.
NPC-1 System Module PAMS Technical Documentation capacity of a battery. The NTC-resistor measures the battery temperature. Temperature and capacity information is needed for charge control. These resistors are connected to BSI and BTEMP pins of the battery connector. The phone has pull-up resistors for these lines so that they can be read by A/D inputs in the phone (see the figure below). Serial resistors in the BSI and BTEMP lines are for ESD protection. Both lines also have spark caps to prevent ESD.

NPC-1 System Module PAMS Technical Documentation An accessory is detected by the HeadInt-line, which is connected to the XEARP inside the system connector. When an accessory is connected, it disconnects XEARP from HEADINT, and the UEM detects it and generates an interrupt (UEMINT) to the MCU. After that, the HOOKINT line is used to determine which accessory is connected. This is done by the voltage divider, which consists of the phone's internal pull-up and accessory-specific pull-down.
NPC-1 System Module PAMS Technical Documentation Interface A 4-wire interface is implemented with 2.5mm diameter round plug/jack which is otherwise like a so-called standard stereo plug, but the innermost contact is split into two.

NPC-1 System Module PAMS Technical Documentation 3-wire chargers, is connected directly to the GND in the PWB module, so the NPC-1 engine does not provide any PWM control for chargers. Charging controlling is done inside the UEM by switching the UEM’s internal charger switch on and off. Interface The fuse F100 protects the phone from too high currents, for example, when broken or pirate chargers are used. L100 protects the engine from RF noises, which may occur in the charging cable.

NPC-1 System Module PAMS Technical Documentation All holes in the PWB are grounded and plated through holes. The only exception is the LED holes, which cannot be grounded. LCD ESD protection for LCD is implemented by connecting the metal frame of the LCD into ground. The connection is only on one side, at the top of the LCD, which is not the best solution. The software takes care of the LCD's crashing in case of an ESD pulse.
