Lab Equipment
The equipment, external supplies and signal sources
needed to operate the board are listed below:
Initial Board Setup Procedure
1. +3.3V to +5V DC Power Supply
2. +5V DC Power Supply
3. High-Speed USB device (i.e. USB memory stick, MP3
4. Full-Speed USB device (i.e. USB memory stick, Mouse,
5. Computer with 2.0 High-Speed USB port
6. Standard USB cable
7. Logic Controller
1. Attach the main evaluation board to a DC power supply
2. Connect a DC power supply at J8 (VBUSHS) and J9
Player, etc.)
etc.)
at J4 (VDD) and J5 (GND). Positive terminal at J4 and
negative terminal at J5. The supply should be capable of
delivering 3.3V to 5V and 100µA of current. Set the
supply voltage to 3.3V.
(VBUSFS). Positive terminal at J8 and J9 and negative
terminal at J5 (GND). The supply should be capable of
delivering 5V and 100mA of current. Set the supply
voltage to 5V. This supply will provide 5V at the V
of the USB “A” type connectors, J8 and J9.
Note: Disconnect the +5V power supply connected to J8 and J9 when powering through Host Controller Bus.
