2.2 Power Supply
2.2.1 Power Supply Sources
The on-board power supply circuitry allows two power supply configurations:
 from USB connector
 from battery connector
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.
– Need of a female battery clip
– Input supply from 8 up to 15V DC (min. 100mA)

2.2.2 VBUS Generator
When using the AT90USB microcontroller in USB host mode, the AT90USBKey should
provide a 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.

2.3 Reset
Although the AT90USB has its on-chip RESET circuitry (c.f. AT90USB Datasheet,
section “System Control and Reset), the AVRUSBKey provides to the AT90USB a
RESET signal witch can come from two different sources:
Figure 2-4 . Reset Implementation
2.3.1 Power-on RESET
The on-board RC network acts as power-on RESET.
2.3.2 RESET Push Button
By pressing the RESET push button on the AVRUSBKey, a warm RESET of the
AT90USB is performed.
2.3.3 Main Clock XTAL
To use the USB interface of the AT90USB, the clock source should always be a crystal
or external clock oscillator (the internal 8MHz RC oscillator can not be used to operate
with the USB interface). Only the following crystal frequency allows proper USB
operations: 2MHz, 4MHz, 6MHz, 8MHz, 12MHz, 16MHz. The AT90USBKey comes with
a default 8MHz crystal oscillator.

2.4 On-board Resources
2.4.1 USB
The AVRUSBKey is supplied with a standard USB mini A-B receptacle. The mini AB
receptacle allows to connect both a mini A plug or a mini B plug connectors.
Figure 2-5 . USB mini A-B Receptacle
When connected to a mini B plug, the AT90USB operates as an “USB device” (the ID
pin of the plug is unconnected) and when connected to a mini A plug, the AT90USB
operates as a “USB host” (the ID pin of the A plug is tied to ground).
2.4.2 Joystick
The 4+1 ways joystick offers an easy user interface implementation for a USB
application (it can emulate mouse movements, keyboard inputs...).
Pushing the push-button causes the corresponding signal to be pulled low, while
releasing (not pressed) causes an H.Z state on the signal. The user must enable
internal pull-ups on the microcontroller input pins, removing the need for an external
pull-up resistors on the push-button.

2.4.3 LEDs
The AT90USBKey includes 2 bi-color LEDs (green/red) implemented on one line. 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.
Figure 2-7 . LEDs Implementation schematic
Table 2-1 . Leds references
2.4.4 Temperature Sensor
The temperature sensor uses a thermistor (R29), or temperature-sensitive resistor. This
thermistor have a negative temperature coefficient (NTC), meaning the resistance goes
up as temperature goes down. Of all passive temperature measurement sensors,
thermistors have the highest sensitivity (resistance change per degree of temperature
change). Thermistors do not have a linear temperature/resistance curve.
The voltage over the NTC can be found using the A/D converter (connected to channel
0). See the AT90USB Datasheet for how to use the ADC. The thermistor value (RT) is
calculate with the following expression:
Where: RT= Thermistor value (Ω) at Ttemperature (°Kelvin)
RH= Second resistor of the bridge -100 KΩ±10% at 25°C
VADC0 = Voltage value on ADC-0 input (V)
VCC = Board power supply

The NTC thermistor used in AT90USBKey has a resistance of 100 KΩ±5% at 25°C (T0)
and a beta-value of 4250 ±3%. By the use of the following equation, the temperature (T)
can be calculated:
Where: RT= Thermistor value (Ω) at Ttemperature (°Kelvin)
ß= 4250 ±3%
R0= 100 KΩ±5% at 25°C
T0= 298 °K (273 °K + 25°K)
The following cross table also can be used. It is based on the above equation.

2.5 In-System Programming
2.5.1 Programming with USB bootloader: DFU (Device Firmware Upgrade)
AT90USB part comes with a default factory pre-programmed USB bootloader located in
the on-chip boot section of the AT90USB. This is the easiest and fastest way to
reprogram the device directly over the USB interface. The “Flip” PC side application, is
available from the Atmel website, offers a flexible an user friendly interface to reprogram
the application over the USB bus.
The HWB pin of the AT90USB allows to force the bootloader section execution after
reset. (Refer to AT90USB datasheet section “boot loader support”). To force bootloader
execution, operate as follow:
 Press both “RST” and “HWB” push buttons
 First release the “RST” push button
 Release the “HWB” push button
For more information about the USB bootloader and “Flip” application, please refer to
the “USB bootloader datasheet document” and “Flip’s user manual”.
Note: The HWB pin is active only if the HWBE fuse is set (default factory configuration).
2.5.2 Programming with AVR JTAGICEmKII
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.
Note: When the JTAGEN Fuse is unprogrammed, the four TAP pins are normal port pins, and
the TAP controller is in reset. When programmed, the input TAP signals are internally
pulled high and the JTAG is enabled for Boundary-scan and programming. The
AT90USB device is shipped with this fuse programmed.

Figure 2-10 . Connecting AVR JTAG ICE to AVRUSBKey
The Flash, EEPROM and all Fuse and Lock Bit options ISP-programmable can be
programmed individually or with the sequential automatic programming option.
Note: See AVR Studio® on-line Help for information.
2.6 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. Thus the on-chip flash bootloader will be erased. It can be
restored after the debug session using the bootloader hex file available from ATMEL
website.
