Product Description

PCF8563T Precision RTC Real Time Clock Memory Module

New Original Precision RTC for Arduino Projects

The PCF8563T is a lowpower CMOS RealTime Clock and calendar module optimized for precise timekeeping in Arduino and embedded systems. This new original chip provides accurate time tracking with I2C interface and battery backup support.

UltraLow Power Only 0.25µA backup current consumption
Wide Voltage Range - Operates from 1.0V to 5.5V
Use CR2032 or CR1220 battery for time retention during power loss
I2C slave address: Read A3h / Write A2h
Ensure correct I2C pull-up resistors for stable communication

Connection Guide

Module pins:

  • VCC: 1.0V to 5.5V power
  • GND: Ground
  • SDA: I2C data line
  • SCL: I2C clock line
  • CLKOUT: Programmable clock output
  • INT: Interrupt output (open-drain)

Arduino wiring:

  • SDA → A4 (Arduino UNO) / SDA pin
  • SCL → A5 (Arduino UNO) / SCL pin
  • VCC → 5V or 3.3V
  • GND → GND
Use 4.7kΩ pull-up resistors on I2C lines
Connect INT pin to Arduino interrupt for alarm events
Do not exceed 5.5V supply voltage
Use level shifting for 3.3V/5V mixed systems

Programming Instructions

Recommended libraries:

  • PCF8563 RTC library
  • RTClib (supports PCF8563)
  • Wire library for I2C communication

Basic setup sequence:

  1. Initialize I2C communication
  2. Set current time and date
  3. Configure alarm if needed
  4. Read time in loop

Easy Integration - Standard Arduino libraries available

Accurate Timekeeping - Maintains time during power loss

Ideal for time-critical projects
