M41T60Q6F

Real Time Clock Overview

The M41T60Q6F is a serial real-time clock (RTC) IC manufactured by STMicroelectronics, designed for precise timekeeping and calendar functions. It operates within a supply voltage range of 1.3V to 4.4V and features an I2C, 2-wire serial interface for data communication. The device maintains time in HH:MM:SS (24-hour) format and date in YY-MM-DD-dd format, with automatic leap year correction. It is housed in a 16-VFQFN package with a bare pad, measuring 3x3 mm. The typical current consumption during timekeeping is between 0.7µA and 0.95µA at voltages from 3.6V to 4.4V. The component supports an industrial operating temperature range of -40°C to +85°C.
