RM-396 System Module Description Board and module connections Energy management Battery and charging BL-4U battery The phone is powered by a 3-pole BL-4U 1000 mAh battery. The three poles are named VBAT, BSI and GND where the BSI line is used to recognize the battery capacity. This is done by means of an internal battery pull down resistor. Page 5 –8 COMPANY CONFIDENTIAL Copyright © 2008 Nokia. All rights reserved.
RM-396 System Module Description Figure 26 Battery pin order The battery temperature can be measured from the main board. Battery connector The battery connector is a blade connector. It has three blades; • BSI (Battery size indicator) • GND (Ground) • VBAT (Battery voltage) The BSI line is used to recognize the battery capacity by a battery internal pull down resistor. Figure 27 Battery connector Charging This phone is charged through the smaller Nokia standard interface (2.0 mm plug).
RM-396 System Module Description Normal and extreme voltages Energy management is mainly carried out in the two Application Specific Integrated Circuits (ASICs) N2300 BETTY and N2200 AVILMA. These two circuits contains a number of regulators. In addition there are some external regulators too. In the table below normal and extreme voltages are shown when a BL-4U battery is used. Table 10 Nominal voltages Voltage Voltage [V] Condition General Conditions Nominal voltage 4.0 Lower extreme voltage 3.

RM-396 System Module Description Figure 33 NFC block diagram RF description Receiver (RX) An analogue signal is received by the phone's antenna. The signal is converted to a digital signal and is then transferred further to the baseband (eg. to the earpiece). The receiver functions are implemented in the RF ASIC. Signals with different frequencies take different paths, therefore being handled by different components. The principle of GSM and WCDMA is the same.
RM-396 System Module Description Transmitter (TX) The digital baseband signal (eg. from the microphone) is converted to an analogue signal, which is then amplified and transmitted from the antenna. The frequency of this signal can be tuned to match the bandwith of the system in use (eg. GSM900). The transmitter functions are implemented in the RF ASIC. Even though the GSM and WCDMA signals are sent via different components, the principles of the transmission is the same.
RM-396 System Module Description Figure 34 Bluetooth interface The Bluetooth has a separate built in antenna and is powered by VBAT and the regulated voltage VIO. For audio applications the Bluetooth has a PCM data bus. In addition a UART (universal asynchronous receiver/ transmitter) is used for data communication and controls. FM radio The FM radio is physically integrated with the Bluetooth into one single module. From a functional point of view they, however, have nothing in common.
RM-396 System Module Description The radio has an automatic band search function, which can search for a strong write/read signal from a certain frequency. When this is found, data is transmitted to the radio. When the signal strength is low, the EM ASIC N2200 (AVILMA) can read data, which is available until the signal is strong again.
