Product Introduction

Overview

The M41T00, produced by STMicroelectronics, is a low power serial real-time clock (RTC) with a built-in 32.768 kHz oscillator that is external crystal controlled. This device is designed to provide accurate timekeeping and is particularly useful in applications requiring reliable clock functions even during power failures. The M41T00 uses eight bytes of RAM for the clock/calendar function, configured in binary-coded decimal (BCD) format, and communicates via a two-line bidirectional I2C bus. It features automatic switchover to a battery supply during power failures, ensuring data retention for over 5 years with a small lithium coin cell.
