The Analog Devices Inc./Maxim Integrated DS1501WEN-T-R is a real-time clock (RTC) with a parallel interface, designed for surface mount applications. This Clock/Calendar component features 256 bytes of NVSRAM for data backup, crucial for maintaining time and configuration data during power loss. It operates within a supply voltage range of 3V to 3.6V and a battery voltage range of 2.5V to 3.7V, with a timekeeping current draw of 4mA maximum at 3V.
Key features include an alarm function, leap year compensation, a watchdog timer, and a square wave output. The DS1501WEN-T-R supports YY-MM-DD-dd date format and HH:MM:SS (24-hour) time format, with Y2K compliance. The component is supplied in a 28-TSSOP package with a 0.465" (11.80mm) width, delivered on tape and reel. This device is commonly utilized in industrial control, medical devices, and consumer electronics requiring accurate timekeeping.
