| Signal Name | I / O | Function | 
| SCL | input | Serial clock input pin. | 
| SDA | Input / Output | Data input and output pin. | 
| FOUT | Output | Frequency output pin with output control function. (C-MOS)Output frequency can be selected as 32.768kHz, 1024Hz, 1Hz. | 
| / RST | Output | Reset output pin.(N-ch open drain) In case of VDD voltage drop detection, a reset signal is outputted. In case of VDD voltage rise detection, it is released reset signal after 60ms. | 
| / IRQ | Output | Interrupts output by Alarm and Timer events.(N-ch open drain) | 
| VDD | - | This is a power-supply pin. It can impress the voltage unlike VIO. | 
| VIO | - | This is a interface power supply pin. This is a pin to supply the voltage same as a host. | 
| Vout | - | Internal voltage output pin. Connect smoothing capacitor of 1.0µF | 
| VBAT | - | This is a power supply pin for backup battery. This is a pin to connect a large-capacity capacitor, a secondary battery,a primary battery. In a backup power supply operating range, the voltage is supplied inside by this pin. | 
| GND | - | Connected to a ground |
