DS1307ZN+T&R Description

Short technical summary and product information.

The DS1307ZN+T&R is a low-power, serial real-time clock (RTC) IC from Analog Devices / Maxim Integrated. It is designed to manage all timekeeping functions, including counting seconds, minutes, hours, day, date, month, and year, with leap-year compensation valid up to 2100. The device features a 56-byte battery-backed, general-purpose NV SRAM with unlimited writes.

 

This RTC utilizes an I2C serial interface for communication with microcontrollers. It operates within a voltage range of 2V to 3.5V and consumes minimal power, drawing less than 500nA in battery-backup mode with the oscillator running. The DS1307ZN+T&R includes automatic power-fail detect and switch circuitry, ensuring continuous timekeeping operation from a backup supply.

 

Available in an 8-SOIC package, the DS1307ZN+T&R is suitable for surface mounting. It supports an industrial operating temperature range of -40°C to 85°C, making it a versatile component for a wide range of applications. The clock can operate in either 24-hour or 12-hour format with an AM/PM indicator.
