Active production — a BOM-stable RTC with onboard NVSRAM
The DS17487-5+ is an active-production real-time clock (RTC) from Analog Devices, carrying a Clock/Calendar type designation with a parallel interface. The part tracks time in YY-MM-DD-dd date format and HH:MM:SS (12/24 hr) time format, with built-in support for Alarm, Daylight Savings, Leap Year, and Square Wave Output — covering the common scheduling and wake-up functions a system architect expects from a single-chip RTC.
Supply rails and timekeeping current — sizing the power budget
Maximum timekeeping current is 3mA at the full supply range, so the battery drain in backup mode is low enough for years of retention with a standard CR2032. This suits indoor equipment (servers, base stations, test gear) but not outdoor or under-hood automotive environments without additional thermal management.
24-EDIP through-hole — legacy-friendly board integration
Housed in a 24-DIP Module (0.600", 15.24mm) / 24-EDIP package, the DS17487-5+ uses through-hole mounting. This footprint is common on industrial PCBs where hand-assembly or socketed installation is preferred, and the 0.600" row spacing matches standard DIP sockets.
Compliance and documentation
The DS17487-5+ is ROHS3 Compliant, meeting EU Directive 2015/863 for restriction of hazardous substances.
