STMicroelectronics Real Time Clock 32 bit D:D:M:Y:C Binary I2C Interface 8-Pin SO-8 Surface Mount M41T82RM6F

STMicroelectronics M41T82RM6F is a highly reliable Real Time Clock (RTC) component designed for precise timekeeping with a 32-bit binary date format including days, months, years, and century counters. It is housed in an 8-pin SO-8 surface mount package with compact dimensions of 5mm by 4mm by 1.5mm, suitable for integration in space-constrained electronic applications.

This RTC supports a wide operating voltage range from 2.0 V to 5.5 V, providing flexibility in system design. It operates with an ultra-low battery supply current of 365 nA ensuring extended battery life for portable or battery-backed applications. The device boasts factory-calibrated accuracy of ±5 ppm after two reflow soldering processes and further accuracy improvements are achievable via its programmable analog and digital calibration circuits.

The M41T82RM6F includes comprehensive timekeeping counters that track tenths and hundredths of seconds along with conventional time divisions up to century, making it suited for advanced timing and calendar functionalities. It features a programmable alarm with an interrupt function, which remains active even during battery backup mode, enhancing its utility in low-power embedded systems.

Automatic switchover and reset output circuitry with a fixed reference guarantees stable operation in varying power conditions. The inclusion of a watchdog timer and battery low flag status further support fault detection and system reliability in industrial environments.

Operating across a robust temperature range from -40 °C to 85 °C, the M41T82RM6F is fit for industrial, automotive, HVAC, and embedded system applications. The serial interface uses an I2C bus protocol supporting up to 400 kHz, ensuring compatibility with modern microcontrollers and digital systems.
