WAKE-UP TIMER IC PROGRAMMABLE WAKE-UP TIMER IC WITH BUILT-IN QUARTZ CRYSTAL
Rev.1.0_00
S-35710M 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. 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 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. 5
