3.2. Pin Functions
Signal
name
I/O
Function
SCL
I
This is the serial clock input pin for I
2C Bus communications.
SDA
I/O
This pin's signal is used for input and output of address, data, and ACK bits,
synchronized with the serial clock used for I
2C communications.
Since the SDA pin is an N-ch open drain pin during output, be sure to connect a suitable
pull-up resistance relative to the signal line capacity.
FOUT
O
This is the C-MOS output pin with output control provided via the FOE pin.
When FOE = "H" (high level), this pin outputs a 32.768-kHz signal.
When output is stopped, the FOUT pin = "L" (low level).
FOE
I
This is an input pin used to control the output mode of the FOUT pin.
When this pin's level is high, the FOUT pin is in output mode. When it is low, output via the
FOUT pin is stopped.
/INT
O
This pins is used to output alarm signals, timer signals, time update signals, and other
signals. This pin is an open drain pin.
VDD
This pin is connected to a positive power supply.
(VDD)
Although this pin has the same potential as VDD, it should not be connected externally.
GND
This pin is connected to a ground.
N.C.
This pin is not connected to the internal IC.
Leave N.C. pins open or connect them to GND or VDD.
(Note) Note with caution that in the RX-8581NB (SON-22 pin), the N.C. pins (pins 14 to
22) are interconnected via the internal frame.
Note: Be sure to connect a bypass capacitor rated at least 0.1 F between VDD and GND.
