M41T82RM6F ST Real-Time Clock | 8-SOIC | I2C, 2.0-5.5V

Product Overview

The M41T82RM6F is a low-power serial real-time clock (RTC) with a built-in 32.768 kHz oscillator and a 400 kHz I2C bus interface. Manufactured by STMicroelectronics, this device is housed in an 8-pin SOIC package and operates over a wide voltage range of 2.0V to 5.5V. It provides timekeeping functions including seconds, minutes, hours, day, date, month, year, and century, with automatic leap year compensation up to 2100. The M41T82RM6F also features a programmable alarm, a watchdog timer, and a square wave output. Its low power consumption (typically 0.9 µA at 3.0V) makes it ideal for battery-powered applications.
