What this RTC is and where it fits
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.
Supply range and temperature grade
Rated for 1.7 V to 5.5 V supply, works directly from a logic rail and continues timekeeping down to 1.7 V. The -40°C to +85°C operating range covers industrial environments.
Lifecycle and sourcing posture
The DS1375T+T&R carries an active lifecycle status and is ROHS3 compliant. For BOM planning, this means no last-time-buy risk in the near term.
