Notes:
1. Operating ranges define the limits between which the functionality of the device is guaranteed. Operating outside the operating ranges can cause long-term reliability problems. Extended operation outside the specified operating ranges can cause permanent damage to the device.
DC CHARACTERISTICS—UNIVERSAL SERIAL BUS
The USBD+ and USBD– pins connect directly to a USB. DC characteristics of these two pins are defined in the USB Version 1.0 specification. Consult this specification for details about overall USB system design. (At the time of this writing, the current USB specification and related information can be obtained on the Web at www.usb.org.)
The Am186CC controller is guaranteed to meet all USB DC specifications. Required analog transceivers are integrated into the Am186CC controller.
