SIGNAL DESCRIPTIONS
The following paragraphs describe the function of each pin.
VCC - VCC is a +5V input supply. Communication with the DS1678 can take place only when VCC is
connected to a +5V supply.
VBAT - Battery input for standard lithium cell or other energy source. All functions of the DS1678 with
the exception of the serial interface circuitry are powered by VBAT when VCC < VBAT. All functions are
powered by VCC when VCC > VBAT. If a battery or other energy source is not used, VBAT should be
connected directly to ground.
GND - Ground
SCL (2-Wire Serial Clock Input) - The SCL pin is the serial clock input for the 2-wire synchronous
communications channel. The SCL pin is an open drain input, which requires an external pull-up resistor.
SDA (2-Wire Input/Output) - The SDA pin is the data Input/Output signal for the 2-wire synchronous
communications channel. The SDA pin is an open drain I/O, which requires an external pull-up resistor.
INT
(Interrupt Input/Output) - The INT pin is an Input/Output that will be activated by an external
device to signify an event has occurred and should be logged. Once the pin is activated, the event will be
recorded in the Event Log Memory and the Event Counter register will be incremented by one.
