Product details

What this RTC is and where it fits

Rated for -40°C to 85°C operation, this part suits industrial control panels, utility metering, telecom infrastructure, and any equipment that must keep accurate time across a factory floor or outdoor enclosure.

Lifecycle and sourcing

Product status is Active per the manufacturer — no end-of-life notice, no last-time-buy window to chase.

Frequently asked questions

Is DP8573AVX/NOPB compatible with 5V logic systems?

Yes, the main supply range is 4.5V to 5.5V, so it runs directly on a 5V rail and its parallel interface is 5V-logic compatible. It is not a 3.3V part on the main supply.

How does DP8573AVX/NOPB compare to DS12887?

Both are parallel-interface 5V RTCs in PLCC packages, but the DP8573AVX/NOPB runs on a 4.5V to 5.5V main supply versus the DS12887's 4.5V to 5.5V as well — functionally similar. The key difference is the DP8573AVX/NOPB draws 1µA max at 5V in timekeeping versus the DS12887's higher typical draw, giving longer battery backup life. Pinout is not identical; verify against your layout before substituting.
