AT90USB646-AUR Frequently Asked Questions (FAQ)
-
The maximum clock frequency for the AT90USB646-AUR is 12 MHz, but it can be overclocked to 16 MHz with some limitations. However, it's recommended to follow the datasheet guidelines for clock frequency to ensure reliable operation.
-
The AT90USB646-AUR has a built-in USB controller, and you can use the LUFA (Lightweight USB Framework for AVR) library to implement USB device functionality. LUFA provides a simple and easy-to-use API for implementing USB devices, and it's specifically designed for AVR microcontrollers like the AT90USB646-AUR.
-
Yes, the AT90USB646-AUR can be used with an external crystal oscillator. The microcontroller has an internal oscillator, but you can also use an external crystal oscillator for more accurate clocking. You'll need to configure the microcontroller to use the external oscillator and ensure that the crystal oscillator is properly connected and configured.
-
The AT90USB646-AUR has 64 KB of flash memory, but not all of it is available for programming. The bootloader and other system components occupy some of the flash memory, leaving around 58 KB available for user programming.
-
You can use a variety of tools to debug and program the AT90USB646-AUR, including Atmel Studio, AVRDUDE, and avr-gcc. You'll need a programming interface like the Atmel-ICE or AVRISP to connect to the microcontroller and upload your code. You can also use debuggers like the Atmel Studio debugger or GDB to step through your code and identify issues.
