Description

M41T00M6E is a real-time clock/calendar IC in the M41T00 family (commonly used in embedded systems). It provides accurate timekeeping (seconds through year, with leap-year handling) and calendar functions, plus optional RAM and alarm features. The device runs on a battery-backup supply so timekeeping continues when main power is off. It uses a 32.768 kHz oscillator (external crystal) to drive the RTC and typically interfaces via I2C (2-wire) at up to 400 kHz. It’s a low-power, compact solution for timestamping data, scheduling events, and maintaining system time across power cycles. Available in small 8-pin packages. For exact voltage range, memory size, pinout, and alarm features, consult the M41T00M6E datasheet.

Features

M41T00M6E features (RTC in I2C family):
- I2C serial interface real-time clock with calendar
- Timekeeping: seconds, minutes, hours (12/24‑hour), day, date, month, year; leap-year aware
- External 32.768 kHz crystal input; optional 1 Hz output
- Battery-backup with VBAT and trickle-charge path for continuous operation during power loss
- On‑chip non-volatile RAM (NVSRAM) for data storage
- Alarm functions (two programmable alarms) and a timer
- Programmable square-wave output
- Wide operating voltage and industrial temperature options
- Package options in 8-pin packages (e.g., SOIC/TSSOP)
Useful for embedded systems needing timekeeping, small data storage, alarms, and low-power operation.

Package

An 8-pin SOIC (small-outline) package.

Pinout

Pin count: 8 pins (SO-8 package).
Function: ST M41T00M6E is an I2C real-time clock with on-chip non-volatile RAM (RTC plus NV memory). It maintains time/date and provides access to ~56 bytes of non-volatile storage over I2C, often with a 32.768 kHz clock input and a SQW/interrupt output.
