Flash Memory Specifications
This section provides details about program/erase times and program-erase endurance for the flash memory.
Program and erase operations do not require any special power sources other than the normal VDD supply. For more detailed
information about program/erase operations, see the Memory section.

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.

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
