NAME
FUNCTION
1
X1
2
X1
Connections for a Standard 32.768kHz Quartz Crystal. The internal oscillator circuitry is designed for
operation with a crystal having a specified load capacitance (C
L
) of 6.0pF. Pin X1 is the input to the oscillator
and can optionally be connected to an external 32.768kHz oscillator. The output of the internal oscillator, pin
X2, is floated if an external oscillator is connected to pin X1.

V
BACKUP
Connection for a Secondary Power Supply. Supply voltage must be held between 1.3V and 5.5V for proper
operation. This pin can be connected to a primary cell, such as a lithium button cell. Additionally, this pin can
be connected to a rechargeable cell or a super cap when used with the trickle-charge feature. If not used,
this pin must be connected to ground. UL recognized to ensure against reverse charging current when used
with a lithium battery. (www.maxim-ic.com/qa/info/ul/
Ground
Serial Data Output. SDA is the input/output for the I
2
C serial interface. This pin is open drain and requires an
external pullup resistor.
Serial Clock Input. SCL is the clock input for the I
2
C interface and is used to synchronize data movement on
the serial interface.

SCL
7
RST
Active-Low, Open-Drain Reset Output. This pin indicates the status of V
CC
relative to the V
PF
specification. As
V
CC
falls below V
PF
, the
RST
pin is driven low. When V
CC
exceeds V
PF
, for t
RST
, the
RST
pin is driven high
impedance. The active-low, open-drain output is combined with a debounced pushbutton input function. This
pin can be activated by a pushbutton reset request. It has an internal 50k
nominal value pullup resistor to
V
CC
. No external pullup resistors should be connected. If the crystal oscillator is disabled, the startup time of
the oscillator is added to the t
RST
delay.
