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.14.1

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 a TEM cell in two package

orientations (North and East).

The maximum radiated RF emissions of the tested configuration in all orientations are less than or equal

to the reported emissions levels.
