The Analog Devices Inc./Maxim Integrated DS1511W is a Real Time Clock (RTC) and Calendar IC featuring a parallel interface. This component provides accurate timekeeping with a 256B memory for storing critical data. Key features include alarm functionality, leap year calculation, integrated NVSRAM for non-volatile data storage, a square wave output, and a watchdog timer for system reliability. The DS1511W supports both 24-hour time format (HH:MM:SS) and YY-MM-DD-dd date format. It operates within a voltage range of 3V to 3.6V for the main supply and 2.5V to 3.7V for battery backup. The device's operating temperature range is 0°C to 70°C. Supplied in a 28-EDIP module (0.600", 15.24mm) for through-hole mounting, this component finds application in various industrial and commercial systems requiring precise timekeeping, such as embedded systems, data logging, and control equipment. The current draw for timekeeping is a maximum of 4mA at 3V.
