Data Sheet
The SSC050-01 is packaged in a 64-pin PQFP. All pins have been placed to optimize their connection to
external components. Power and ground distribution has also been optimized for core and high current I/
O connections. All serial interface pins as well as the interrupt output are 5 volt tolerant. VDD and
VDD2 should be connected to a 3.3 volt supply with no more than 10% tolerances.
