DS1339C-33 Description

Short technical summary and product information.

The DS1339C-33 is a low-power, I2C serial real-time clock (RTC) manufactured by Analog Devices / Maxim Integrated. This device provides seconds, minutes, hours, day, date, month, and year information, with automatic adjustments for month lengths and leap years. It supports both 24-hour and 12-hour formats with an AM/PM indicator.

 

Key features include two programmable time-of-day alarms and a programmable square-wave output. The integrated power-sense circuit automatically switches to a backup supply during power failures, ensuring continuous operation of the clock, date, and alarm functions. It also includes trickle-charge capability.

 

Designed for surface mounting, the DS1339C-33 comes in a 16-SOIC package with an integrated crystal. Its operating temperature range is -40°C to 85°C, and it operates with a voltage range of 1.3V to 3.7V. The I2C interface allows for serial data transfer.

 

Applications for this RTC include handheld devices, consumer electronics, office equipment, medical devices, and telecommunications infrastructure.
