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.
VGEN1
Output of general purpose 1 regulator.
VGEN2DRV
Drive output for the VGEN2 external PNP transistor.
VGEN2
Output of general purpose 2 regulator.
VINGEN3DRV
1. Input for the VGEN3 regulator when no external PNP
transistor used. Typically connected to BP.
2. Drive output for VGEN3 in case an external PNP
transistor is used on the application. In this case, this pin
must be connected the base of the PNP transistor.
VGEN3
Output of general purpose 3 regulator.
VSRTC
Output regulator for the SRTC module on the processor.
The VSRTC regulator provides the CLK32KMCU output level
(1.2 V). Additionally, it is used to bias the Low Power SRTC
domain of the SRTC module integrated on certain FSL
processors.
GNDREG1
Ground for regulators 1.
GNDREG2
Ground for regulators 2.
GNDREG3
Ground for regulators 3.
GPO1
General purpose output 1. Intended to be used for battery
thermistor biasing. In this case, connect a 10 K
Ω resistor
from GPO1 to ADIN5, and one from ADIN5 to GND.
GPO2
General purpose output 2.
GPO3
General purpose output 3.
GPO4
General purpose output 4. It can be configured for a
muxed connection into Channel 7 of the GP ADC.
CONTROL LOGIC
LICELL
Coin cell supply input and charger output. The LICELL pin
provides a connection for a coin cell backup battery or
supercap. If the main battery is deeply discharged, removed,
or contact-bounced (i.e., during a power cut), the RTC
system and coin cell maintained logic will switch over to the
LICELL for backup power. This pin also works as a current-
limited voltage source for battery charging. A small capacitor
should be placed from LICELL to ground under all
circumstances.
XTAL1
32.768 kHz Oscillator crystal connection 1.
XTAL2
32.768 kHz Oscillator crystal connection 2.
GNDRTC
Ground for the RTC block.
CLK32K
32 kHz Clock output for peripherals. At system start-up,
the 32 kHz clock is driven to CLK32K (provided as a
peripheral clock reference), which is referenced to SPIVCC.
The CLK32K is restricted to state machine activation in
normal on mode.
CLK32KMCU
32 kHz Clock output for processor. At system start-up, the
32 kHz clock is driven to CLK32KMCU (intended as the CKIL
input to the system processor) referenced to VSRTC. The
driver is enabled by the start-up sequencer and the
CLK32KMCU is programmable for Low Power Off mode
control by the state machine.
RESETB AND RESETBMCU
Reset output for peripherals and processor respectively.
These depend on the Power Control Modes of operation (See
Functional Device Operation on page 48). These are meant
as reset for the processor, or peripherals in a power up
condition, or to keep one in reset while the other is up and
running.
