3.13
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 V
For more detailed information about program/erase operations, see the Memory section.
3.14
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.

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
with V
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.
The frequency of this clock is controlled by a software setting.
