S-35710 Series 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. _______
3. RST (Input for reset signal) pin
_______ This pin inputs the reset signal. The timer is reset when inputting "L" to the RST pin. The INT pin is set to "H" when _______ _______ inputting "H" to the RST pin, and the timer starts the operation. The RST pin has a built-in chattering elimination _______ circuit. Regarding the chattering elimination circuit, refer to "
RST Pin
". Besides, S-35710B01I is the product with pull-up resistor, and S-35710C01I is the product without 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. The interrupt signal output (time-out type) is handshake time-out. Regarding the operation of the interrupt signal output, refer to "
INT Pin Interrupt Signal Output
". Besides, S-35710C01I is the Nch open-drain output product, and S-35710B01I is the CMOS output product.
5. XIN, XOUT (Connection for quartz crystal) pins
Connect a quartz crystal between the XIN pin and the XOUT pin.
6. 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
".
7. VSS pin
Connect this pin to GND.
