Serial I/O Signals
CTL I/O Technology
The serial I/O is implemented using Fairchild’s
proprietary differential CTL I/O technology. During data
transfers, the serial I/O are powered up to a normal
operating mode around .5V. Upon completion of a data
transfer, the serial I/O goes to a lower power mode
around V

The serial I/O signal traces should not cross between
the master and the slave. The pin locations have been
designed to eliminate the need to cross traces. See
Table 7, Figure 4, and Figure 5.
