DS1307N+ Description

Short technical summary and product information.

The DS1307N+ is a low-power, full binary-coded decimal (BCD) clock/calendar with 56 bytes of NV SRAM, designed for efficient timekeeping. It communicates via a bidirectional I2C serial bus, making it easy to interface with most microcontrollers.

 

This clock/calendar manages all timekeeping functions, including seconds, minutes, hours, day, date, month, and year, with leap-year compensation valid up to 2100. It supports both 24-hour and 12-hour formats with an AM/PM indicator. The device includes a built-in power-sense circuit that automatically switches to a backup supply during power failures, ensuring continuous operation.

 

Key features include a programmable square-wave output signal and low power consumption, drawing less than 500nA in battery-backup mode with the oscillator running. The DS1307N+ is available in an 8-pin PDIP package, suitable for through-hole mounting.

 

Its operating temperature range is -40°C to +85°C, and it requires a voltage between 2V and 3.5V, consuming approximately 200µA at 5V. The memory size is 56 bytes, and it supports I2C and 2-Wire Serial interfaces.
