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
information about program/erase operations, see the Memory chapter in the Reference Manual for this device
(MC9S08MM128RM).
Freescale Semiconductor
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.
