M41T81SMY6F ST Real-Time Clock | 18-SOX | I2C, 2.0-5.5V

Product Overview

The M41T81SMY6F is a low-power serial real-time clock (RTC) with a built-in 32.768 kHz oscillator and a factory-calibrated, temperature-compensated crystal (TCXO). It provides timekeeping functions including seconds, minutes, hours, day, date, month, year, and century. The device communicates via an I2C bus and operates over a wide voltage range of 2.0V to 5.5V. It is housed in an 18-pin SOX package (300 mil width) and is ideal for applications requiring accurate timekeeping with minimal power consumption.
