M41T11MH6F

An introduction to M41T11MH6F: It is an I2C real-time clock/calendar IC in STMicroelectronics’ M41Txx family. The device provides persistent timekeeping with a battery backup, so the clock continues during power outages. It typically uses a 32.768 kHz oscillator and stores time and date information (seconds, minutes, hours, day, date, month, year) with leap-year correction. Features commonly include programmable alarms, a configurable square-wave output, and a trickle-charge facility to keep the backup source charged from the main supply. It’s designed for microcontroller-based systems requiring accurate timekeeping, event stamping, and low power operation. Communication with a host MCU happens over I2C to read/write time data and configure alarms or outputs. For exact electrical characteristics, pinout, and packaging (including MH6F variant specifics), consult the M41T11MH6F datasheet.

Here are typical features of the M41T11MH6F (RTC/clock-chip family):
