mikroElektronika RTC click Quick Start Manual

RTC click
1. Introduction
RTC Click is an accessory board in mikroBus™
PCF8583P
form factor. It features the serial
real-time clock (RTC). It is a low-power, full
binary-coded decimal (BCD) clock/calendar.
Board uses I C interface for communication
2
lithium battery
and features a 3V/230mA
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.
2. Soldering the headers
Before using your click board, make sure
to solder the provided 1x8 male headers
to both sides of the board. Two 1x8 male
headers are included with the board in
the package.

Turn the board upward again. Make sure
to align the headers so that they are
perpendicular to the board, then solder the
pins carefully.
3. Plugging the board in
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.
