DS1337 Description

Short technical summary and product information.

The Analog Devices DS1337 is a low-power, serial real-time clock (RTC) that manages all timekeeping functions. It counts seconds, minutes, hours, day, date, month, and year, with leap-year compensation valid up to 2100. The device features two programmable time-of-day alarms and a programmable square-wave output, which defaults to 32kHz on power-up.

 

Data is transferred serially through an I2C bus, making it easy to interface with most microcontrollers. The DS1337 operates within a wide voltage range of 1.8V to 5.5V, with timekeeping maintained as low as 1.3V. Its operating temperature range is -40°C to +85°C, suitable for industrial applications.

 

This clock/calendar IC is available in an 8-pin DIP (Through Hole) package. It supports both 24-hour and 12-hour formats with an AM/PM indicator. The DS1337 is designed for applications such as handheld devices, consumer electronics, office equipment, medical devices, and telecommunications.
