It is not a 3.3V part on the main supply."},{"question":"How does DP8573AVX/NOPB compare to DS12887?","answer":"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."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/DP8573AVX-NOPB","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/DP8573AVX-NOPB when reusing this data.
