📥 Download Datasheet

General Description

The M41T00S is a low-power serial real-time clock (RTC) with a built-in 32.768 kHz oscillator (external crystal controlled).

Eight bytes of the SRAM are used for the clock/calendar function and are configured in binary coded decimal (BCD) format.

Addresses and data are transferred serially via a two line, bidirectional I²C interface.

Overview

M41T00S 8 1 SO8, 8-pin SOIC.

Key Features

  • 2.0 to 5.5 V clock operating voltage.
  • Counters for seconds, minutes, hours, day, date, month, year, and century.
