A.12 EMC Performance
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 should consult Freescale applications notes such as AN2321, AN1050, AN1263,
AN2764, and AN1259 for advice and guidance specifically targeted at optimizing EMC performance.
A.12.1 Radiated Emissions
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 all four package orientations
(North, South, East and West). For more detailed information concerning the evaluation results, conditions
and setup, please refer to the Radiated RF Emissions test 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.

NOTES:
1. This data based on qualification test results. Not tested in production.
2. The reported emission level is the value of the maximum emission, rounded up to the next whole dB, from
among the mesured orienations in each frequency range.
3. IEC levels are as specified in IEC 61967-1 and IEC 61967-2.
4. SAE levels are as specified in SAE J1752/1 and SAE J1752/3.
