EMC Performance
3.16
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.
3.16.1
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).

No.
These values are hardware state machine controlled. User code does not need to count cycles. This information supplied for
calculating approximate time to program and erase.
The program and erase currents are additional to the standard run I

Typical endurance for Flash was evaluated for this product family on the 9S12Dx64. For additional information on how
Freescale defines typical endurance, please refer to Engineering Bulletin EB619, Typical Endurance for Nonvolatile Memory.
Typical data retention values are based on intrinsic capability of the technology measured at high temperature and de-rated to
25 °C using the Arrhenius equation. For additional information on how Freescale defines typical data retention, please refer to
Engineering Bulletin EB618, Typical Data Retention for Nonvolatile Memory.
