INTRODUCTION
The FUSB302 evaluation board (EVB) and included
software allows customers a complete platform to evaluate
the Type
−
C interface detection solution the FUSB302
provides. The EVB is designed for both stand
−
alone
operation and connection to test equipment for specific
testing requirements. The FUSB302 software provides both
fully automatic control and manual control of the FUSB302
functions. With a single connection to a PC and a couple
configurations in the GUI, the EVB can function as a source,
sink or dual
−
role port.
Description
The FUSB302 targets system designers looking to
implement a DRP/DFP/UFP USB Type
−
C connector with
low amount of programmability.
The FUSB302 does the USB Type
−
C detection including
attach, and orientation. The FUSB302 integrates the
physical layer of the USB BMC Power Delivery (PD)
protocol to allow up to 100 W of power and role swap. The
BMC PD block enables full support for alternative
interfaces of the Type
−
C specification.

POWER CONFIGURATION
The FUSB302 EVB is designed to be able to be powered
from a PC connection or powered externally based on the
testing requirements.
Power Supplied from Board
The FUSB302 can fully operate from the VBUS input of
the micro
−
B USB receptacle J2. To operate the EVB, the
USB power should be provided to the board over the
micro
−
B USB. Then, the on board regulator generates VDD,
which is 3.3V for device supply. Once valid USB power is
provided, the indicator LED, 3.3V, will be turned on.
I
2
C Communication
Communication with the FUSB302 is done through I
2
C
accesses. The EVB allows different ways of connecting I
2
C
masters to the FUSB302.
Direct I
2
C Connection
Customers that want to directly connect their I
2
C masters
to the EVB can connect the I
2
C master signals to the SCL,
SDA and INT_N test points.
PC I
2
C Connection
The EVB uses a PIC32MX250F128 micro
−
controller as
an I
2
C master to control the FUSB302. This is the
communication method used by the FUSB302 GUI. By
connecting the PC to the micro
−
B USB receptacle J2, the
EVB automatically powers the microcontroller and
