STMicroelectronics Timekeeper® M41T256YMH7F is a Clock/Calendar Real Time Clock (RTC) IC featuring a 32KB NVSRAM memory. This component utilizes an I2C, 2-Wire Serial interface for communication. It supports both YY-MM-DD-dd and HH:MM:SS:hh (24 hr) time and date formats, with integrated leap year functionality. The device operates within a supply voltage range of 4.5V to 5.5V, with a battery voltage requirement of 2.5V to 3.5V. The timekeeping current consumption is a maximum of 2.5mA at 4.5V. The M41T256YMH7F is provided in a 44-BSOP (0.337", 8.56mm Width) package, requiring a SNAPHAT, and is supplied on Tape & Reel (TR). This RTC is commonly employed in applications within the industrial and automotive sectors.
