Description
Configuration
1
INT1
Alarm interrupt 1 output pin.
Depending on the mode set by the INT1
register and status register, it outputs low or
Clock when time is reached. It is disabled by
rewriting the status register.
Nch open drain output
(No protective diode on the
side of VDD)
2
XIN
3
XOUT
Crystal oscillator connect pin (32,768 Hz)
(Internal Cd, External Cg)
4
VSS
Negative power supply pin (GND)
5
INT2
Alarm interrupt 2 output pin.
Depending on the mode set by the INT2
register and status register, it outputs low or
Clock when time is reached. It is disabled by
rewriting the status register.
Nch open drain output
(No protective diode on the
side of VDD)
6
SCL
Serial clock input pin.
Follow the specification with great care to the
rising/falling time of the SCL signal because
the signal is treated at its rising/falling edge.
CMOS input (No protective
diode on the side of VDD)
7
SDA
Serial data input/output pin.
This pin is usually pulled up to VDD via a
resistor, and connected to other open-drain or
open-collector output devices in wired OR
configuration.
Nch open drain output
(No protective diode on the
side of VDD)
CMOS input
8
VDD
Positive power supply pin.
