Appendix A Electrical Characteristics
If the Freescale S08USBV1 implementation has electrical characteristics that deviate from the standard or
require additional information, this space would be used to communicate that information.

Electromagnetic compatibility (EMC) performance is highly dependant on the environment in which the
MCU resides. Board design and layout, circuit topology choices, location and characteristics of external
components as well as MCU software operation all play a significant role in EMC performance. The
system designer can consult Freescale applications notes such as AN2321, AN1050, AN1263, AN2764,
and AN1259 for advice and guidance specifically targeted at optimizing EMC performance.
18.5.1
Microcontroller radiated RF emissions are measured from 150 kHz to 1 GHz using the TEM/GTEM Cell
method in accordance with the IEC 61967-2 and SAE J1752/3 standards. The measurement is performed
with the microcontroller installed on a custom EMC evaluation board while running specialized EMC test
software. The radiated emissions from the microcontroller are measured in a TEM cell in two package
orientations (North and East). For more detailed information concerning the evaluation results, conditions
and setup, please refer to the EMC evaluation report for this device.
The maximum radiated RF emissions of the tested configuration in all orientations are less than or equal
to the reported emissions levels.

The reported emission level is the value of the maximum emission, rounded up to the next whole number, from among the
measured orientations in each frequency range.
