Product details

I2C RTC with 0.6µA timekeeping

The DS1337C# is an I2C real-time clock/calendar from Analog Devices that tracks time in HH:MM:SS (12/24 hr) and date in YY-MM-DD-dd format, with integrated leap-year compensation and a programmable square-wave output. It draws just 0.6µA max during timekeeping at 1.3V–1.8V, so it adds negligible drain to a battery-backed design — the RTC itself won't be the weak link in a coin-cell lifetime budget.

Package and compliance

Housed in a 16-SOIC wide-body package (7.50 mm width), surface-mount, supplied in tube format.

Frequently asked questions

What is the DS1337C#'s timekeeping current draw?

Maximum timekeeping current is 0.6µA at 1.3V–1.8V supply, making it suitable for battery-backed applications where every microamp matters.
