Analog Devices Inc./Maxim Integrated DS12887A is a Real Time Clock (RTC) Clock/Calendar module featuring 114B of NVSRAM for data retention. This component offers parallel interface access and supports both 12 and 24-hour time formats, along with YY-MM-DD-dd date formatting. Key features include alarm functionality, daylight savings compensation, and leap year correction, all driven by a square wave output. The device operates within a supply voltage range of 4.5V to 5.5V, with a timekeeping current draw of a maximum of 15mA at 5V. Battery voltage support ranges from 2.5V to 4V. The DS12887A is housed in a 24-EDIP package with a 0.600" (15.24mm) lead span for through-hole mounting. It is commonly utilized in industrial control systems, medical equipment, and consumer electronics requiring accurate timekeeping and data buffering.
