RM-70 System module Nokia Customer Care Phone description Introduction This chapter describes the baseband module including engine, power management, interfaces, audio etc. The baseband is based on BB5.0 with a RAPGSM main processor and Retu/Tahvo energy management. All blocks that require high voltage process are in Tahvo and all other in Retu. The RF part is based on the ASIC Ahne. RM-70/Nokia 7370 operates on the GSM900/1800/1900 bands.

RM-70 System module Nokia Customer Care Board and module connections Figure 49 Board and module connections Engine Engine modules The engine contains • RF module with Ahne ASIC • Main processor with integrated memory (Baseband) • Energy management - Retu and Tahvo (Baseband) • SDRAM and NOR flash memories RF engine The RF module performs the high frequency operations of the engine for GSM. In both transmitter and receiver, the modulator and demodulator operate at the channel frequency.
RM-70 System module Nokia Customer Care • Ahne RF ASIC (application specific integrated circuit) • Front end module (FEM) module (Power amplifier and Antenna switch) The RF engine also includes: • Voltage controlled oscillators (VCO and VCTCXO) • SAW filters The baseband section controls the RF module through the serial bus, RFBus. This passes information about eg. frequency band and mode of operation. Ahne RF ASIC controls the mode of operation, and further sends control signals to the front end module.
RM-70 System module Nokia Customer Care Modes of operation The functional behavior can be divided into seven different states. Since the UEMEK controls the regulated power distribution of the phone, each of these states will affect the general functionality of the phone: • No supply • Backup • Power off • Reset • Power on • Deep sleep Battery and charging Battery Note: For technical data, see Battery endurance (page ). This device uses the BL-4B battery, a 700 mAh minimum Li-ion battery.
RM-70 System module Nokia Customer Care Charging This phone is charged through the smaller Nokia standard interface (2.0 mm plug). The old standard charger (3.5 mm) can be used together with the CA-44 charger adapter. Figure 52 Old (left) and new (right) charger plugs Charging is controlled by energy management, and external components are needed to protect the baseband module against EMC, reverse polarity and transient frequency deviation.

RM-70 System module Nokia Customer Care Figure 55 FM radio interface Camera Figure 56 Camera interface This phone is equipped with a 1.3 megapixel camera. The module has only one operating mode; raw pixel data output. A hardware accelerator includes features like pixel defect correction, colour interpolation, image sharpness enhancement, selective noise filtering, cropping and scaling. The image can be JPEG-compressed in real-time.
RM-70 System module Nokia Customer Care Figure 57 RAPGSM/Retu SIM interface connections SIM Logic level shifting The SIM interface can be programmed to support 3V and 1.8V SIM cards. Retu contains a SIM interface called Logic level shifting. A register in Retu selects the supply voltage when the SIM interface is powered down. SIM Power up/down The SIM power up/down sequence is generated in Retu. This means that Retu generates the reset switch (RST) signal to the SIM.
