Analog Devices Inc./Maxim Integrated DS17485S-3 is a Clock/Calendar IC featuring a 4KB NVSRAM for timekeeping data storage. This component offers a parallel interface for accessing its clock and calendar functions, supporting both YY-MM-DD-dd and HH:MM:SS (12/24 hr) formats. Key features include alarm functionality, daylight savings compensation, leap year calculation, and a square wave output. The device operates within a supply voltage range of 2.7V to 3.7V and requires a battery voltage between 2.5V and 3.7V for timekeeping, with a maximum current draw of 2mA. Packaged in a 24-SOIC (0.295", 7.50mm Width) for surface mounting, the DS17485S-3 is suitable for applications in industrial control, telecommunications, and data acquisition systems requiring accurate timekeeping and non-volatile data retention. It is supplied in a tube.
