MikroElektronika
RTC PROTO (Real time clock PROTO)
The RTC PROTO enables the microcontroller to keep the real time and date, providing the alarm function. It is used to generate an
interrupt. Due to baterry cell the RTC PROTO enables the microcontroller to keep the real time when the power supply is off. The RTC
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 RTC PROTO communicates to the microcontroller by using the serial I
2
C interface.
The RTC PROTO is placed on the development system’s port that is connected to the built-in I
2
C microcontroller module.

PCF8583P circuit pins are used for connecting to the
microcontroller. Their functions are as follows:
INT - Output pin used to generate an interrupt
SCL - Serial clock line
SDA - Serial data line
