Product details

The DS1375T+T&R: Serial real-time clock/calendar in a 6-TDFN (3x3) package with exposed pad. Tracks time in HH:MM:SS (12/24 hr) and date in YY-MM-DD-dd format, with automatic leap-year correction. The I²C (2-wire) serial interface connects directly to most microcontrollers using two pins (SCL, SDA).

Square wave output and alarm — built-in interrupt generation

Includes a programmable square wave output and an alarm function. The square wave can be set to one of several frequencies and fed to a microcontroller interrupt pin or used as a periodic wake-up source.

Rated for 1.7 V to 5.5 V supply, works directly from a logic rail and continues timekeeping down to 1.7 V.

Frequently asked questions

Does DS1375T+T&R have a square wave output?

Yes, the DS1375T+T&R includes a programmable square wave output that can be set to several frequencies for use as a periodic interrupt or wake-up signal.
