Timekeeping current is specified at the low end of the supply range; at 3.3V the actual draw is slightly higher but remains below 1µA typical, which is the figure to use for worst-case battery life calculations. ## Timekeeping features and format support The RTC supports both 12-hour and 24-hour time formats with HH:MM:SS resolution, and the date format is YY-MM-DD-dd, covering the full calendar including leap year compensation. Built-in features include an alarm, leap year tracking, and a square wave output — the alarm can be set to generate an interrupt on the SQW/INT pin, and the square wave output provides a programmable frequency reference without an external timer.","metaTitle":"DS1337S+T&R RTC, I2C, 8-SOIC, Industrial Temp","metaDescription":"Analog Devices DS1337S+T&R real-time clock, I2C interface, 1.8V-5.5V supply, 0.6µA timekeeping, -40°C to +85°C, active production, 8-SOIC.
