DEVICE CONFIGURATION

The device supports a large number of features (some mutually exclusive), and must be configured in order to correctly

function when attached to a USB host controller. Microchip provides a comprehensive software programming tool,

MPLAB Connect Configurator (formerly ProTouch2), for OTP configuration of various USB7252P functions and regis-

ters. All configuration is to be performed via the MPLAB Connect Configurator programming tool. For additional infor-

mation on this tool, refer to the MPLAB Connect Configurator programming tool product page at http://

www.microchip.com/design-centers/usb/mplab-connect-configurator.

Additional information on configuring the USB7252P is also provided in the “Configuration of the USB7202/USB725x”

application note, which contains details on the hub operational mode, SOC configuration stage, OTP configuration, USB

configuration, and configuration register definitions. This application note, along with additional USB7252P resources,

can be found on the Microchip USB7252P product page at www.microchip.com/USB7252P.

Note:

The USB7252P requires external firmware to operate. Functions such as Power Delivery will not operate

without external firmware. Refer to the “Configuration of the USB7202/USB725x” application note for addi-

tional information.

Note:

Device configuration straps and programmable pins are detailed in Section 3.3, Configuration Straps and

Programmable Functions.

Refer to Section 7.0, Device Interfaces for detailed information on each device interface.
