Pin Functions

1. SDA (I/O for serial data) pin

This is a data input / output pin for I2C-bus interface. The SDA pin inputs / outputs data by synchronizing with a clock

pulse from the SCL pin. This pin has CMOS input and Nch open-drain output. Generally in use, the SDA pin is pulled

up to VDD potential via a resistor, and is used with wired-OR connection of other device of Nch open-drain output or

open collector output.

2. SCL (Input for serial clock) pin

This is a clock input pin for I2C-bus interface. The SDA pin inputs / outputs data by synchronizing with this clock pulse.

3. RST

_______

(Input for reset signal) pin

This pin inputs the reset signal. The timer is reset when inputting "L" to the RST

_______

pin, and the timer starts the

operation when inputting "H". The RST

_______

pin has a built-in chattering elimination circuit. Regarding the chatterging

elimination circuit, refer to " RST

_______

Pin".

Besides, the RST

_______

pin has a pull-up resistor.

4. INT (Output for interrupt signal) pin

This pin outputs an interrupt signal. The interrupt signal is output when the time written to the wake-up time register

comes. Regarding the operation of the interrupt signal output, refer to " INT Pin Interrupt Signal Output".

Besides, the INT pin output form is CMOS output.

5. VDD (Positive power supply) pin

Connect this pin with a positive power supply. Regarding the values of voltage to be applied, refer to

" Recommended Operation Conditions".

6. VSS pin

Connect this pin to GND.
