T he 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 T able II for list of
packaging dimensions and consult individual data sheets of the
two components for further details.)
