Preliminary Electrical Characteristics
3.15
The USB electricals for the USB On-the-Go module conform to the standards documented by the
Universal Serial Bus Implementers Forum. For the most up-to-date standards, visit
If the Freescale USB On-the-Go implementation has electrical characteristics that deviate from the
standard or require additional information, this space would be used to communicate that information.

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.
