Preliminary Electrical Characteristics

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 chapter in the Reference
Manual for this device (MCF51JE256RM).

The frequency of this clock is controlled by a software setting.
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.
Typical endurance for flash was evaluated for this product family on the HC9S12Dx64. 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.
