MikroElektronika
RTC2 PROTO (Real time clock PROTO)
The RTC2 PROTO enables the microcontroller to keep the real time and date including corrections for a leap year and months that
have less than 31 days. It has an alarm function, featuring automatic power-fail detection. It is used to generate an interrupt and square
wave output signal. Due to baterry cell the RTC2 PROTO enables the microcontroller to keep the real time when the power supply
is off. The RTC2 PROTO is linked to the development system by connecting 1x5 male connector provided on the additional board to
the proto board provided on the development system’s ports. The RTC2 PROTO communicates to the microcontroller by using the
serial I
2
C interface. The RTC2 PROTO is placed on the development system’s port that is connected to the built-in I
2
C microcontroller
module.

The DS1307 circuit pins are used for connecting to
the microcontroller. Their functions are as follows:
SQW - Pin used to generate an interrupt or
square wave output signal
SCL - Serial clock line
SDA - Serial data line
1x5 male is used for connecting the additional
board to the development system via proto board
