FUNCTIONAL DESCRIPTION
FUNCTIONAL PIN DESCRIPTION
Because of an order from the United States International Trade Commission, BGA-packaged product lines and part numbers indicated here currently are not
available from Freescale for import or sale in the United States prior to September 2010: MC13892VK and MC13892VL in 139, 186 MAPBGA packages.
SW4OUT
Switcher 4 output. Buck switcher for external memory and
peripherals.
GNDSW4
Ground for switcher 4.
DVS1 AND DVS2
Switcher 1 and 2 DVS input pins. Provided for pin
controlled DVS on the buck switchers targeted for processor
core supplies. The DVS pins may be reconfigured for
Switcher Increment / Decrement (SID) mode control. When
transitioning from one voltage to another, the output voltage
slope is controlled in steps of 25 mV per time step. These
pins must be set high in order for the DVS feature to be
enabled for each of switchers 1 or 2, or low to disable it.
SWBSTIN
Switcher BST input. The 2.2
μH switcher BST inductor
must be connected here.
SWBSTOUT
Power supply for gate driver for the internal power NMOS
that charges SWBST inductor. It must be connected to BP.
SWBSTFB
Switcher BST feedback. When SWBST is configured to
supply the UVBUS pin in OTG mode the feedback will be
switched to sense the UVBUS pin instead of the SWBSTFB
pin.
GNDSWBST
Ground for switcher BST.
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.
VGEN1DRV
Drive output for the VGEN1 external PNP transistor.
