CIF camera module will be used in RH-20. Camera is connected to baseband (UPP) 
through HW accelerator IC. External 1.8V regulator is used as a power supply (VDIG) for 
camera module and HW accelerator together with VFLASH2.

CIF camera has a resolution of 352 x 288. Pixel size is 5.6um x 5.6um. Both camera and 
HW accelerator support sleep functionality in order to minimize the current consump-
tion.

The IR interface when using transceiver with 1.8V I/O is designed into the UPP. The IR 
link supports speeds from 9600 bit/s to 1.152 MBit/s up to distance of 80 cm. Transmis-
sion over the IR if half-duplex.

UEM contains the SIM interface logic level shifting. SIM interface can be programmed to 
support 3V and 1.8V SIMs. SIM supply voltage is selected by a register in the UEM. It is 
only allowed to change the SIM supply voltage when the SIM IF is powered down.

The SIM power up/down sequence is generated in the UEM. This means that the UEM 
generates the RST signal to the SIM. Also the SIMCardDet signal is connected to UEM. 
The card detection is taken from the BSI signal, which detects the removal of the battery.
