 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 V_DD 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. ENBL (Input for fixed-cycle interrupt signal output control) pin
This pin controls the clock pulse output from the INT pin. The INT pin outputs the fixed-cycle interrupt signal when the
ENBL pin is "H". The INT pin is fixed when the ENBL pin is "L".
4. INT (Output for fixed-cycle interrupt signal) pin
This pin outputs a fixed-cycle interrupt signal. The fixed-cycle interrupt signal of the frequency and duty ratio, which is
set to the fixed-cycle interrupt signal setting register, is output. Regarding the operation of the fixed-cycle interrupt
signal output, refer to " INT Pin Fixed-cycle Interrupt Signal Output".
Also, the INT pin output form of Nch open-drain output / CMOS output can be selected.
5. XIN, XOUT (Connection for crystal oscillator) pins
Connect a crystal oscillator 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.
