M41T62 Hardware Hookup
The M41T62 is a Serial RTC (400kHz I2C bus) with alarm. It is ideal for handheld and battery-powered applications. It is also perfect for short back-up applications where only a few days or weeks of non-volatility is required, usually using capacitor back-up.

The M41T62 is offered in an ultra-small QFN package, making it a perfect fit for compact applications.
