<description>&lt;b&gt;AVR Devices&lt;/b&gt;&lt;p&gt;
Version 7 - August 1, 2011.&lt;br&gt;&lt;br&gt;
Added ATmega164P/324P/644P devices for DIP and TQFP.
&lt;p&gt;
Version 4 - March 11, 2008.&lt;br&gt;&lt;br&gt;
This library now includes ONLY ATMEL AVR microcontrollers.  It is the result of merging all other available device libraries available at http://www.cadsoft.de/download as of the time it was made.  In addition to the legacy AT90* devices, it includes most ATMEGA devices including the new 48/88/168, most ATTiny devices and a set of ISP and JTAG pin headers.&lt;p&gt;
