Introduction

Electrical Modules

The NEM-2 phone comprises two modules: the main PWB (EM21) and UI PWB (EM20)

The system module EM11 consists of Radio Frequency (RF) and baseband (BB). User Inter­face (UI) contains only LCD connector, backlight LEDs, keypad layout and Earpiece cir­cuit.

FM radio is located on the main PWB EM21.

The modules are connected with each other by B2B connectors.

In general NEM-2 baseband hardware consists of two parts:

• GSM Phone

• Audio Player

Phone part is based on DCT4 common baseband architecture. Qwerty-keyboard is con­nected to UPP ASIC.

Audio Player part contains functionality needed for stereo audio features. MMC interface
and USB interface are included as well.

Phone controls power up and reset of Audio Player part via dedicated hardware signals.
In operational modes both parts are running asynchronous, communication takes place
via UART based asynchronous serial interface.

Special audio routing provides for the connection between audio sources and audio out­puts. Audio lines are part of the Phone- Audio Player interface as well.

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.

User Interface Modules

Keyboard

NEM-2 features a Qwerty keyboard, two soft keys and send/end keys with additional 4­way rocker for gaming and music features. The keys are connected in a 6x7-matrix with
the UPP. Key pressing is detected by scanning procedure.

The applied “Bulls Eye” keypads are located on the UI board.

A “hotkey” for activating the music features and the volume up and down keys are
located on the engine board and connected to GENIO ports.

Display

130*130 pixel passive matrix colour STN display is used.
