PIN DESCRIPTION
PIN
NAME
FUNCTION
1
EVENT
Event Input. The EVENT pin is the input the DS1682 monitors to determine when
an event occurs. When the pin is pulled high, the contents of the EEPROM are
transferred to the ETC and the oscillator starts. The ETC begins to count in quarter-
second increments. When the EVENT pin falls to logic 0, the event counter
increments, and the event counter, ETC, and user-memory data are stored in the
EEPROM array. When the EVENT pin changes states, the 2-wire bus is
unavailable for communications for tEW (falling) and tER (rising). The EVENT input
is also deglitched (tG) to prevent short noise spikes from triggering an event.
2, 7
N.C.
No Connect. This pin is not connected internally.
3
ALARM
Active-Low Alarm Output. The DS1682 monitors the values in the ETC for the
programmed value in the alarm register. When the ETC matches the alarm value,
the alarm flag (AF) is set. Once set, the alarm flag cannot be reset. See the
operating descriptions for the AOS and AP bits for details about the operation of
the
ALARM pin.
4
GND
Ground
5
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 input that requires an
external pullup resistor.
6
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 pullup resistor.
