UC3 32-bit microcontrollers are designed for audio applications:
• AT32UC3A0512AU-ALUT
• AT32UC3A0512AU-ALTRA
• AT32UC3A0256AU-ALUT
• AT32UC3A0128AU-ALUT
• AT32UC3A1512AU-AUR
• AT32UC3A1256AU-AUR
• AT32UC3A3256AU-ALUT
• AT32UC3B0512AU-Z2UR
• AT32UC3B0128AU-A2UT
• AT32UC3B0128AU-Z2UR
• AT32UC3C0512CAU-ALUT
These devices are distinguished by the AU letters before the dash in their part numbers.
Please note that for a given microcontroller, not all package versions exist. Additional audio
part numbers can be created upon customer demand.
The difference between an Audio microcontroller (e.g. AT32UC3A0512AU-ALUT)
and its standard counterpart (e.g. AT32UC3A0512-ALUT) is not relevant to the
user code.
As far as the user code is concerned, Audio parts are 100% compatible with the
standard devices.
Atmel licensed Audio firmware IP cores such as the Proprietary Communication
Protocol with iPod®, iPhone® or iPad® devices, MP3, WMA or AAC decoders will
only work on Audio microcontrollers. These Audio firmware IP cores will not
execute on standard microcontrollers (e.g. AT32UC3A0512-ALUT). The same
rule may apply to additional IP cores in the future.
For technical information on an audio part (e.g. AT32UC3A0512AU-ALUT), please refer to
the datasheet, architecture manual and technical reference manual of the standard
counterpart (e.g. AT32UC3A0512-ALUT). The same applies for other technical
documents such IBIS files, qualification packages, etc.
Tools that support the standard version of AVR UC3 microcontrollers also
support their audio counterpart.
