 + 
 +1.8V core with I/O up to 3.3V. Many mixed-signal devices will have an on-die LDO for generating 1.8 from 3.3 however higher end devices such as programmable logic typically expect an external 1.8V supply. 
 + 
 +4-5 aluminum layers with tungsten vias, titanium-based barrier metal, and cobalt silicide contacts.

-Layouts can vary, as does presence or absence of CMP filler between bond pads.+Power ring and pad layouts can vary somewhat, as does presence or absence of CMP filler between bond pads. 
 + 
 +On-die Flash/EEPROM option available. 
 +==== Identification ==== 
 + 
 +The CMP filler pattern is distinctive and can be used as positive ID. Fill polygons are rectangles with 2:1 aspect ratio, long side oriented parallel to the prevailing routing direction.
