DS1307Z+ Description

Short technical summary and product information.

The DS1307Z+ from Dallas Semiconductor is a versatile serial real-time clock (RTC) designed for accurate timekeeping. It manages all timekeeping functions, including seconds, minutes, hours, day, date, month, and year, with leap-year compensation valid up to 2100. The device includes 56 bytes of battery-backed, general-purpose RAM with unlimited write capability, making it suitable for storing small amounts of data.

 

Communication is handled via a simple I2C serial interface, allowing easy integration with most microcontrollers. The DS1307Z+ boasts low power consumption, drawing less than 500nA in battery-backup mode with the oscillator running. It also features automatic power-fail detection and switch circuitry, ensuring continuous timekeeping operation from a backup supply.

 

This component is available in an 8-pin SO package, minimizing space requirements on printed circuit boards. It operates within a commercial temperature range of 0°C to 70°C and requires a 5V supply voltage. The DS1307Z+ is ideal for applications requiring reliable timekeeping and non-volatile data storage.
