A real-time clock module that provides
accurate timekeeping, ideal for projects requiring date and time tracking. It
features low power consumption and a simple I2C interface for easy integration
with microcontrollers like Arduino.
Description
The DS1307 RTC
I2C Module AT24C32 offers precise timekeeping and calendar
functionality, making it an essential tool for applications requiring accurate
and reliable timing. This module is built around the DS1307 real-time clock
(RTC) IC, known for its performance and durability.
Key Features
Accurate Timekeeping: Tracks seconds, minutes, hours, day,
date, month, and year, with leap-year compensation valid up to 2100.
Battery Backup: Designed with a battery input for 3V
lithium cells or similar power sources, ensuring continuous operation
during power outages (includes a reliable LIR2032 battery).
Low Power Consumption: Consumes less than 500 nA in battery
backup mode with the oscillator running, providing efficient power usage.
Versatile Interface: Features a two-wire I2C interface
for easy communication and integration with various systems.
Compact and Durable Design: Available in 8-pin DIP or SOIC
package options, offering flexibility for different installations. UL
recognized for safety and reliability.
Data Storage: Includes 56 bytes of non-volatile
RAM to store critical data, maintaining integrity even during power loss.
1Hz Output Pin: Provides a 1Hz square wave output
for additional functionality or synchronization.
