Page 6: Power Supply
USB powered When used as a USB device bus powered application, the AVRUSBKey can be directly powered via the USB VBUS power supply line. Battery powered The external battery connector should be used when the AT90USBKey is used as a USB host. This mode allows the AT90USBKey to provide a 5V power supply from its VBUS pin. - Page 7 5V power supply over the VBUS pin of its USB mini AB connector. A couple of transistors allows the UVCON pin of the AT90USB to control the VBUS generation (See Figure 2-3). In this mode the AT90USBKey is powered by external battery power supply source.

They are connected to the high nibble of “Port D” of AT90USB (PORTD[4..7]). To light on a LED, the corresponding port pin must drive a high level. To light off a LED, the corresponding port pin must drive a low level.

The AT90USB can be programmed using specific JTAG link. To use the AVR JTAGICEmkII with an AT90USBKey an optional HE10 connector should be soldered to J9 footprint. Then the JTAG probe can be connected to the AT90USBKey as shown in Figure 2-10... -
Page 14: Debugging
Debugging 2.6.1 Debugging with AVR JTAG ICE mkII The AT90USBKey can be used for debugging with JTAG ICE MK II. Connect the JTAG ICE mkII as shown in Figure 2-10, for debugging, please refer to AVR Studio® Help information. When using JTAG ICE MK II for debugging, and as AT90USB parts are factory configured with the higher security level set, a chip erase operation will be performed on the part before debugging. -
