CMOS I/O Signals
System Control Signals
The system control signals consist of M/S, /RES,
/STBY(SLEW), PAR/SPI, and CKSEL. For connectivity
flexibility, these signals are over-voltage tolerant to the
maximum supply voltage connected to the device. This
allows these signals to be tied HIGH to either a V
V
signals are all CMOS inputs and should never be
allowed to float.
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

Parallel I/O Signals
The parallel data port signals consist of the DP[17:0],
CNTL[5:0], R/W, and STRB1(0)(WCLK1(0)) signals.
These signals have built-in voltage translation, allowing
the signals of the master and slave to be connected to
different V
Serial I/O Orientation Logic
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.
