Freescale Semiconductor 25
3.12 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.
If the Freescale S08USBV1 implementation requires additional or deviant electrical characteristics, this
space would be used to communicate that information.

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.
