Product details

The STMicroelectronics M48T08Y-10MH1F is a Timekeeper® real-time clock/calendar with a parallel interface, designed for systems that need to track date and time without continuous CPU polling. It handles YY-MM-DD-dd date format and HH:MM:SS time in 24-hour mode, and includes a watchdog timer and leap-year compensation — features that make it a drop-in fit for legacy industrial controllers, telecom line cards, and embedded instrumentation that run on a 5V rail.

Timekeeping current and what it means

The timekeeping current draw is 3mA maximum across the supply range.
