2 Evaluation Board Basic Setup
Figure 2 shows the basic connections of the evaluation board with the external equipment.
The power supply can come from three sources:
•
A regulated lab power supply connected to the banana plugs J2, J3 and J5.
•
Any AC-DC converter block, able to generate a DC power supply of 2.7 V min / 6.5 V max / 400 mA.
•
The +5 V coming from the USB bus when connected to a computer or hub, able to support USB-powered
devices. In this case the ON/OFF switch, S33, has no effect and power is always on. When the
board is powered from the USB bus, the application is bus-powered and the embedded application
must be designed for this.
The communication with an external host can be accommodated by either:
•
A standard USB2.0 full speed interface or
•
A standard RS-232 serial interface (TX/RX only).
The board is loaded by default with the USB CCID application. Refer to Section 3 for information on
setting up and running this application.
