VCC-IO
When interfacing with 3.3v external logic connect VCC-IO to the 3.3v supply of the external logic,
otherwise connect to VCC to drive out at 5v CMOS level. This pin must be connected to VCC from
the target electronics or EXTVCC.
EXTVCC
PORTVCC if module is to be powered by the USB port (typical configuration)
PORTVCC
USB port (typical configuration). 500mA maximum current available to USB adapter and target
electronics if USB device is configured for high power.

suspend. Can be used to control power to external logic using a P-Channel Logic Level
MOSFET switch. Enable the Interface Pull-Down Option in EEPROM when using the PWREN# pin
in this way.
TXDEN
RI# (IN) Ring Indicator Control Input. When the Remote Wakeup option is enabled in the
EEPROM, taking RI# low can be used to resume the PC USB Host controller from suspend.
