Ordering Information
3.11 Flash 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 in the reference
manual.

1 The frequency of this clock is controlled by a software setting.
2 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.
3 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/D, Typical Endurance for Nonvolatile Memory.
4 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/D, Typical Data Retention for Nonvolatile Memory.
