DS1307 Real-Time Clock IC by IIVVERR 5-Piece DIP-8 56-Byte Serial RTC

Description

Product Overview

The IIVVERR DS1307 Real Time Clock IC is engineered to meet the demanding requirements of modern embedded systems, offering precise timekeeping in a compact DIP‑8 footprint. This serial RTC integrates a 56‑byte non‑volatile RAM, allowing developers to store configuration data, timestamps, or small datasets directly on the chip. Operating voltage ranges from 4.5 V to 5.5 V, the device is compatible with a broad spectrum of microcontroller platforms, from 8‑bit AVR families to 32‑bit ARM Cortex‑M cores. Its low‑power design consumes only 500 nA in standby mode, extending battery life in remote or portable applications. The DS1307 also features a built‑in crystal oscillator circuit that maintains accurate time across a temperature range of –40 °C to +85 °C, ensuring reliability in harsh industrial environments.

Manufactured by IIVVERR, the IC is supplied in a pocket‑size DIP‑8 package with a 2.54 mm pitch, facilitating easy insertion into standard breadboards and printed circuit boards. The package includes five individual units per box, each weighing approximately 2 g, making it a cost‑effective choice for both prototype development and volume production. The part number 3c539ee68d268eb uniquely identifies this component within the IIVVERR catalog, and it is listed under the Clock Integrated Circuits sub‑category of Timing Management Products.

Usage

Designed for versatility, the DS1307 RTC finds application in a multitude of scenarios. In industrial automation, it can synchronize data logging events, ensuring that sensor readings are accurately timestamped for later analysis. In consumer electronics, the chip powers real‑time displays in clocks, thermostats, and home automation hubs, providing users with reliable time information without the need for constant network connectivity. Hobbyists and makers benefit from its straightforward I²C interface, which allows rapid integration with popular development boards such as Arduino, Raspberry Pi, and ESP32. The low standby current makes it an excellent choice for battery‑operated devices like remote weather stations, portable medical instruments, and wildlife tracking tags, where power efficiency is paramount.

Because the DS1307 includes a small amount of battery‑backed RAM, developers can store configuration parameters that survive power cycles, eliminating the need for external EEPROM in many designs. The chip’s robust construction tolerates up to 1000 insertion cycles, and its click‑type installation method simplifies assembly on both prototype and production PCBs. Whether you are building a data logger that records temperature and humidity over months, a smart alarm clock that syncs with user preferences, or a custom IoT gateway that timestamps incoming sensor data, the DS1307 provides a dependable foundation for time‑critical functions.

FAQ

What voltage range does the DS1307 support?

The DS1307 operates reliably from 4.5 V to 5.5 V, making it suitable for most 5 V logic systems and allowing flexibility in power‑supply design.

How much power does the RTC consume in standby mode?

In standby mode the device draws only about 500 nA, which helps to maximize battery life in low‑power or energy‑harvesting applications.

Can the DS1307 be used with a microcontroller that only supports SPI?

While the DS1307 is primarily an I²C device, many microcontrollers provide software‑implemented I²C over general‑purpose I/O pins, allowing you to interface the RTC even if native SPI support is unavailable.

Is the 56‑byte RAM battery‑backed?

Yes, the RAM retains its contents as long as a backup battery is connected to the V_BAT pin, preserving data through power interruptions.

What is the maximum number of devices that can share the same I²C bus with the DS1307?

The I²C bus can accommodate up to 127 devices, provided each has a unique address and the bus capacitance stays within the specification limits.
