STMicroelectronics M41ST85WMX6 is a Clock/Calendar IC featuring an I2C, 2-Wire Serial interface. This Real Time Clock (RTC) offers robust timekeeping capabilities with a 44-byte memory for configuration and data storage. Key features include alarm functionality, leap year calculation, integrated NVSRAM for non-volatile data retention, square wave output, a power-on reset supervisor, and a watchdog timer. It operates within a supply voltage range of 2.7V to 3.6V and a battery voltage range of 2.5V to 3.5V, with a typical timekeeping current consumption of 0.5mA at 2.7V. The device supports both YY-MM-DD-dd date format and HH:MM:SS:hh (24-hour) time format. Supplied in a 28-SOIC (0.295", 7.50mm Width) surface mount package, the M41ST85WMX6 is suitable for applications in industrial automation, consumer electronics, and automotive systems requiring reliable timekeeping and system monitoring.
