Quality Control: Learn More
The Analog Devices Inc./Maxim Integrated DS1501YN is a Real Time Clock (RTC) with a parallel interface, housed in a 28-DIP (0.600", 15.24mm) package. This clock/calendar IC offers 256B of NVSRAM for data storage and features a comprehensive set of functionalities including alarm capabilities, leap year compensation, and a watchdog timer. It supports both timekeeping and a 24-hour time format (HH:MM:SS), alongside a date format of YY-MM-DD-dd. Operating across a wide temperature range of -40°C to 85°C, the DS1501YN requires a supply voltage of 4.5V to 5.5V, with battery backup support ranging from 2.5V to 3.7V. Its robust feature set, including a square wave output, makes it suitable for applications in industrial control, data logging, and telecommunications.
