Appendix A Electrical Characteristics
A.1.3.3
Oscillator
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: S12XE products in 208 MAPBGA packages
The pins EXTAL, XTAL dedicated to the oscillator have a nominal 1.8 V level. They are supplied by
VDDPLL.
A.1.3.4
TEST
This pin is used for production testing only.
A.1.4
Current Injection
Power supply must maintain regulation within operating V
DD35
or V
DD
range during instantaneous and
operating maximum current conditions. If positive injection current (V
in
> V
DD35
) is greater than I
DD35
,
the injection current may flow out of V
DD35
and could result in external power supply going out of
regulation. Ensure external V
DD35
load will shunt current greater than maximum injection current. This
will be the greatest risk when the MCU is not consuming power; e.g., if no system clock is present, or if
clock rate is very low which would reduce overall power consumption.
A.1.5
Absolute Maximum Ratings
Absolute maximum ratings are stress ratings only. A functional operation under or outside those maxima
is not guaranteed. Stress beyond those limits may affect the reliability or cause permanent damage of the
device.
This device contains circuitry protecting against damage due to high static voltage or electrical fields;
however, it is advised that normal precautions be taken to avoid application of any voltages higher than
