3.5 Interfaces
The module provides multiple interfaces for both debug and demonstration.
• USB 2.0 full speed compatible interface
• 16 x 2 monochrome character LCD display
• BDM Debug and Development interface
• Four individual pushbuttons can be used as input and have interrupt generation capability
• Four individual LEDs can be used as indicators for debug or status
• A fully buffered RS232 serial interface with RTS/CTS control is supplied as a secondary COM port
3.5.1 USB Interface
Primary communication with an application device or platform is provided by a USB port with a USB “B”
receptacle plug. USB connectivity is provided by a FTDI FT232R USB < > UART device that appears as
a virtual COM port (VCP) to a connected PC. PC drivers are provided with the module. For pinout
information, see Section , “The 1320x-QE128EVB RF circuitry contains a printed metal F-antenna
(ANT1).”.
The USB interface is configured as a “bus powered” device and can draw all required power from the USB
interface. The device is USB 2.0 full speed compatible.
