MECHANICAL CONSIDERATIONS
The chipset has been specifically designed to meet not only cost
and power consumption requirements but also the physical
dimensions. State-of-the-art package technology was used to
achieve the smallest possible geometries. (See Table II for list of
packaging dimensions and consult individual data sheets of the
two components for further details.)
