FUNCTIONAL PIN DESCRIPTION
REGULATORS
VINIOHI
Input of VIOHI regulator. Connect this pin to BP in order to supply VIOHI regulator.
VIOHI
Output regulator for high voltage IO. Fixed 2.775 V output for high voltage level interface.
VINPLL AND VINDIG
The input of the regulator for processor PLL and Digital regulators respectively. VINDIG and VINPLL can be connected to
either BP or a 1.8 V switched mode power supply rail, such as from SW4 for the two lower set points of each regulator (the 1.2
and 1.25 V output for VPLL, and 1.05 and 1.25 V output for VDIG). In addition, when the two upper set points are used (1.50 and
1.8V outputs for VPLL, and 1.65 and 1.8V for VDIG), they can be connected to either BP or a 2.2V nominal external switched
mode power supply rail, to improve power dissipation.
VPLL
Output of regulator for processor PLL. Quiet analog supply (PLL, GPS).
VDIG
Output regulator Digital. Low voltage digital (DPLL, GPS).
VVIDEODRV
Drive output for VVIDEO external PNP transistor.
VVIDEO
Output regulator TV DAC. This pin must be connected to the collector of the external PNP transistor of the VVIDEO regulator.
VINAUDIO
Input regulator VAUDIO. Typically connected to BP.
VAUDIO
Output regulator for audio supply.
VINUSB2
Input regulator VUSB2. This pin must always be connected to BP even if the regulators are not used by the application.
VUSB2
Output regulator for powering USB PHY.
VINCAMDRV
1. Input regulator camera using internal PMOS FET. Typically connected to BP.
2. Drive output regulator for camera voltage using external PNP device. In this case, this pin must be connected to the base
of the PNP in order to drive it.
VCAM
Output regulator for the camera module. When using an external PNP device, this pin must be connected to its collector.
VSDDRV
Drive output for the VSD external PNP transistor.
VSD
Output regulator for multi-media cards such as micro SD, RS-MMC.
