Pin Function 
Signal Name Input/
Output		 Function
SCL Input This is a shift clock input pin for serial data transmission.
SDA Bi-directional This is the data input/output pin for serial data transfer.
IRQ1 Output This pin outputs interrupt signals ("L" level) for alarm, timer, time update,
and 32.768kHz. This is an N-ch open-drain output.
/IRQ2 Output This pin outputs interrupt signals ("L" level) for timer and FOUT.
This is a C-MOS output.
VDD Supply This is a power-supply pin.
GND Supply This pin is connected to a ground.

Terminal connection / External dimensions


(Unit: mm)

The metal case inside of the molding compound may be exposed on the top or bottom of this product.
This purely cosmetic and does not have any effect on quality, reliability or electrical specs.

Footprint (Recommended)

(Unit: mm)

To maintain stable operation, provide a 0.1uF by-pass capacitor
at a location as near as possible to the power source terminal of the crystal product (between Vcc - GND).
