The DS1307+ is an integrated circuit (IC) component developed by Maxim Integrated Products. It is a real-time clock (RTC) with an I2C (Inter-Integrated Circuit) interface, offering accurate timekeeping for various applications. This IC gained popularity due to its ease of use, precise timekeeping, and low power consumption. Let's explore its key features and capabilities.
The DS1307+ utilizes a 32.768kHz quartz crystal oscillator to maintain accurate timekeeping, ensuring a minimal time drift over extended periods. It comes equipped with a built-in power sense circuitry that automatically switches to the backup power supply (typically a coin cell battery) during power failures, ensuring uninterrupted timekeeping functionality.
One of the key features of the DS1307+ is its simple I2C interface, which allows easy integration with various microcontrollers and other digital devices. The I2C bus enables communication with the DS1307+ using just two wires, making it ideal for space-constrained applications. This component supports standard (100kHz) and fast (400kHz) I2C communication speeds, offering flexibility for different system configurations.
The DS1307+ provides a wide range of timekeeping capabilities, including support for hours, minutes, seconds, day, date, month, and year. It also incorporates a programmable square wave output, which can be used as an interrupt signal or as a clock signal for other devices in the system
