Appendix A Electrical Characteristics
A.13 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 V_DD supply.
For more detailed information about program/erase operations.

1 _{Typical values are based on characterization data at VDD = 5.0 V, 25°C unless otherwise stated.}
2 _{The frequency of this clock is controlled by a software setting.}
3 _{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.
4 _{Typical endurance for Flash is based on the intrinsic bitcell performance. For additional information on how}
Freescale Semiconductor defines typical endurance, please refer to Engineering Bulletin EB619/D, Typical
Endurance for Nonvolatile Memory.
5 _{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 Semiconductor defines
typical data retention, please refer to Engineering Bulletin EB618/D, Typical Data Retention for Nonvolatile Memory.
A.14 USB Electricals
The USB electricals for the S08USBV1 module conform to the standards documented by the Universal
Serial Bus Implementers Forum. For the most up-to-date standards, visit http://www.usb.org.
