Datasheet

The processor is available in a 478-pin Micro-FCPGA package. The package mechanical 

dimensions are shown in 

The mechanical package pressure specifications are in a direction normal to the surface 

of the processor. This requirement protects the processor die from fracture risk due to 

uneven die pressure distribution under tilt, stack-up tolerances and other similar 

conditions. These specifications assume that a mechanical attach is designed 

specifically to load one type of processor.

The processor package substrate should not be used as a mechanical reference or load-

bearing surface for the thermal or mechanical solution.
