The Analog Devices Inc./Maxim Integrated DS12C887 is a Clock/Calendar module featuring an 113B parallel interface. This real-time clock (RTC) component operates with a supply voltage range of 4.5V to 5.5V and a battery voltage of 2.5V to 4V, drawing a maximum of 15mA at 4.5V. Key features include alarm functionality, daylight savings time adjustment, leap year compensation, and an integrated NVSRAM for data retention. The device outputs a square wave and supports both 12/24 hour time formats and YY-MM-DD-dd date formats. Designed for through-hole mounting, it is housed in a 24-DIP Module (0.600", 15.24mm) package. This component is suitable for applications in industrial control, telecommunications, and consumer electronics where accurate timekeeping and calendar functions are critical.
