DS1307: The Ultimate Guide to the 32-Pin, 3V Serial Timekeeping Chip

Introduction

The DS1307IDRG is a highly accurate, low-power, 32-pin, 3V serial timekeeping chip that offers a wide range of features and applications. This comprehensive guide provides an in-depth look at the DS1307IDRG, covering its specifications, operation, programming, and troubleshooting.

Specifications

• Clock Accuracy: ±2 minutes per month (at 25°C)
• Voltage Range: 2.3V to 5.5V
• Operating Temperature Range: -40°C to +85°C
• Interface: Serial I2C bus
• Power Consumption: 500nA (typical) in Battery Backup Mode

Operation

The DS1307IDRG operates as a slave device on an I2C bus. It communicates with a master device (e.g., a microcontroller) using the following protocol:

• Write: The master device sends a start condition, the device address (0x68), and the data to be written.
• Read: The master device sends a start condition, the device address (0x69), and the location to be read. The DS1307IDRG then transmits the data at that location.

Programming

The DS1307IDRG is programmed using the I2C bus. The following steps outline the basic programming procedure:

1. Set the write pointer to the desired location.
2. Send the data value to be stored at that location.
3. Repeat steps 1 and 2 for each data value to be programmed.

Applications

The DS1307IDRG has a wide range of applications, including:

• Real-time clocks
• Time-based security systems
• Data loggers
• Industrial controls
• Automotive electronics
