AT90USBKey Hardware User Guide Section 2 Using the AT90USBKey This chapter describes the AVRUSBKey and all its resources. 2.1 Overview Figure 2-1 . AT90USBKey Overview AT90USBKey Hardware User Guide 2-5 7627A–AVR–04/06 Using the AT90USBKey 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) Figure 2-2 .

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.

AT90USBKey Hardware User Guide 2-7 7627A–AVR–04/06 Using the AT90USBKey 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 VCC R6 47k C8 220nF RESET RST 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. 2-8 7627A–AVR–04/06 AT90USBKey Hardware User Guide Using the AT90USBKey 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 .

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. Figure 2-6 .

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 references LED Reference AT90USB Connection Color D2 PORTD.4 Red PORTD.5 Green PORTD.6 Green PORTD.7 Red D5 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: R T = ( R H ⋅ V ADC 0 ) ⁄ ( V CC – V ADC 0 ) Where: R T = Thermistor value (Ω) at T temperature (°Kelvin) R H = Second resistor of the bridge -100 KΩ ±10% at 25°C VADC0 = Voltage value on ADC-0 input (V) VCC = Board power supply 2-10 7627A–AVR–04/06 AT90USBKey Hardware User Guide Using the AT90USBKey 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: β T = ------------------------------R β ⎛ ln T⎞ + ----------⎝ R ⎠ T0 0 Where: R T = Thermistor value (Ω) at T temperature (°Kelvin) ß = 4250 ±3% R 0 = 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. Table 2-2 . Thermistor Values versus Temperature AT90USBKey Hardware User Guide Temp. (°C) RT (KΩ) Temp. (°C) RT (KΩ) Temp. (°C) RT (KΩ) Temp.

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: 2.5.2 The HWB pin is active only if the HWBE fuse is set (default factory configuration). 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: AT90USBKey Hardware User Guide 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. 2-13 7627A–AVR–04/06 Using the AT90USBKey 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. 2-14 7627A–AVR–04/06 AT90USBKey Hardware User Guide Section 3 Troubleshooting Guide Figure 3-1 . Troubleshooting Guide Problem Reason The Green “VCC-ON” LED is not on No power supply Verify the power supply source (check battery charge or USB connection). The AVR JTAG ICE probe is not connected Connect the JTAG ICE 10-PIN header to the correct AVRUSBKey JTAG header (page 13) The memory lock bits are programmed Erase the memory before programming with JTAG ICE. The fuse bits are wrongly programmed Check the fuse bits with JTAG ICE AVRUSBKey does not work The AT90USB cannot be programmed Solution Force bootloader execution with HWB under reset. Can not connect to USB bootloader Serial/USB cable is not connected, or power is off AVR Studio does not detect the AVR JTAG ICE. PC COM port is in use USB bootloader erased after a JTAG debugging session: reprogram the USB bootloader with JTAG. Connect serial cable to RS232 (STK500 AVR ISP) and check power connections Connect serial cable to USB (JATG ICE MKII, AVR ISPmkIIl) and check power connections Disable other programs that are using PC COM port.
