M41T81M6F ST Real Time Clock

The M41T81M6F is a low-power serial real-time clock (RTC) from STMicroelectronics in an 8-pin SOIC package, featuring a built-in 32.768 kHz oscillator and I2C interface . For selection, verify supply from 2V to 5.5V, confirm -40°C to +85°C industrial temperature range, note ultra-low battery supply current of 0.6µA typical, 20 bytes of non-volatile SRAM for clock/calendar and control functions, programmable alarm and watchdog timer, oscillator stop detection, and software clock calibration . Features include automatic switchover and deselect circuitry, battery low flag, and square wave output. Ideal for data logging systems, industrial controllers, medical equipment, consumer electronics, and any application requiring accurate time and date tracking with low power consumption.
