The Analog Devices Inc./Maxim Integrated DS1689S is a real-time clock and calendar IC with a parallel interface. This 28-SOIC component features 114 bytes of NVSRAM for timekeeping data and supports both 12 and 24-hour time formats, along with a YY-MM-DD-dd date format. Operating across temperature ranges of 0°C to 70°C, it supports supply voltages of 2.7V to 3.3V and 4.5V to 5.5V, with battery support from 2.5V to 3.7V. Current draw for timekeeping is a maximum of 2mA at 3V and 3mA at 5V. This device is commonly utilized in industrial control, automotive, and consumer electronics applications requiring accurate timekeeping and non-volatile data storage.
