It tracks time in HH:MM:SS:hh format (12/24 hour selectable) and date in YY-MM-DD-dd, with integrated alarm and leap-year compensation. The parallel interface suits designs where a microcontroller reads and writes time registers over a shared address/data bus — common in industrial controllers, embedded instrumentation, and telecom line cards that need a hardware timebase independent of the main processor. ## Temperature grade and environment Rated for -40°C to 85°C operation, so it fits outdoor telecom cabinets, factory-floor controllers, and engine-bay-adjacent electronics that see temperature swings. The 28-PLCC J-lead package is a common footprint for RTCs and SRAMs; it sits flat on the board and is hand-solderable for prototyping or rework. ## Lifecycle and sourcing Listed as Active with ROHS3 compliance. For BOM planning, the active status means no last-time-buy pressure and no need to qualify a drop-in replacement today.","metaTitle":"DP8573AV/NOPB RTC Clock/Calendar, Parallel, 28-PLCC, Active","metaDescription":"DP8573AV/NOPB real-time clock/calendar with parallel interface, alarm, leap year. 4.5V-5.5V supply, -40 to 85°C, 1µA timekeeping.
