The Analog Devices Inc./Maxim Integrated DS1501YZ-T-R is a real-time clock (RTC) and calendar integrated circuit featuring a parallel interface. This component includes 256 bytes of NVSRAM for data storage. Key features include alarm functionality, leap year compensation, and a watchdog timer. The device operates within a supply voltage range of 4.5V to 5.5V, with a separate battery voltage input of 2.5V to 3.7V for timekeeping. It supports both timekeeping (max 5mA @ 4.5V ~ 5.5V) and provides a square wave output. The date is formatted as YY-MM-DD-dd, and the time as HH:MM:SS (24 hr). Packaged in a 28-SOIC (0.295", 7.50mm Width) surface mount configuration, it is supplied on tape and reel. Operating temperature ranges from 0°C to 70°C. This component is suitable for applications requiring precise timekeeping and calendar functions, including industrial control, data logging, and embedded systems.
