Product description

The AT90USBKey is a low-cost demonstration board based on the AT90USB1287 microcontroller. It allows the quick evaluation of AVR microcontrollers and the AT90USB family. The key simply connects to the USB port of a personal computer to retrieve on-board documentation and run AVR programs. Designers can either run demonstration programs or their own application. It also allows hardware developments by giving access to the JTAG port and all the IOs of the microcontroller. An external power supply can be used for USB host or stand-alone operation.


The AT90USBKey provides the following features:
* AT90USB QFN64
* AVR Studio® software interface (1)
* USB software interface for Device Firmware Upgrade (DFU bootloader) (2)
* Power supply flagged by “VCC-ON” LED:
– regulated 3.3V
– from an external battery connector (for reduced host or OTG operation)
– from the USB interface (USB device bus powered application)
* JTAG interface (connector not mounted):
– for on-chip ISP
– for on-chip debugging using JTAG ICE
* Serial interfaces:
– 1 USB full/low speed device/host/OTG interface
* On-board resources:
– 4+1-ways joystick
– 2 Bi-Color LEDs
– temperature sensor
– serial dataflash memories
– all microcontroller I/O ports access on 2x8pin headers (not mounted)
* On-board RESET button
* On-board HWB button to force bootloader section execution at reset.
* System clock:
– 8 MHz crystal
