1. Introduction
RTC Click is an accessory board in
mikroBus
™
form factor. It features the
PCF8583P
serial
real-time clock (RTC). It is a low-power, full
binary-coded decimal (BCD) clock/calendar.
Board uses I
2
C interface for communication
and features a 3V/230mA
lithium battery
as a backup power supply which ensures that
timekeeping operation continues even when
the main power supply goes OFF. Board is set
to use 3.3V power supply by default. Solder
PWR SEL
SMD jumper to 5V position if used
with 5V systems.
Once you have soldered the headers your
board is ready to be placed into desired
mikroBUS™ socket. Make sure to align the
cut in the lower-right part of the board
with the markings on the silkscreen at the
mikroBUS™ socket. If all the pins are aligned
correctly, push the board all the way
into the socket.

4. Board applications
RTC click is ideal for applications which
require real-time clocks, calendars and
programmed alarms. Communication with
the board is done over standard I
2
C interface.
The Real-Time Clock (RTC) has 24 hour or
12 hour format, it has programmable alarm,
timer, and interrupt function.
Turn the board upward again. Make sure
to align the headers so that they are
perpendicular to the board, then solder the
pins carefully.
Turn the board upside down, so that
bottom side is facing you upwards. Place
shorter parts of the header pins in the
both soldering pad locations.
