DS3231 s\u00fa lacn\u00e9, extr\u00e9mne presn\u00e9 I2C hodiny re\u00e1lneho \u010dasu (RTC) s integrovan\u00fdm teplotne kompenzovan\u00fdm kry\u0161t\u00e1lov\u00fdm oscil\u00e1torom (TCXO) a kry\u0161t\u00e1lom. Zariadenie obsahuje bat\u00e9riov\u00fd vstup, odp\u00e1ja hlavn\u00e9 nap\u00e1janie a udr\u017eiava presn\u00e9 meranie \u010dasu. Integrovan\u00fd oscil\u00e1tor zlep\u0161uje dlhodob\u00fa presnos\u0165 zariadenia a zni\u017euje po\u010det komponentov v\u00fdrobnej linky. DS3231 je k dispoz\u00edcii v komer\u010dn\u00fdch a priemyseln\u00fdch teplotn\u00fdch rozsahoch s pou\u017eit\u00edm 16-pinov\u00e9ho 300mil SO puzdra.
\nRTC uchov\u00e1va inform\u00e1cie o sekund\u00e1ch, min\u00fatach, hodin\u00e1ch, dni, d\u00e1tume, mesiaci a roku. Menej ako 31 dn\u00ed v mesiaci sa d\u00e1tum ukon\u010denia automaticky uprav\u00ed vr\u00e1tane opr\u00e1v pre priestupn\u00fd rok. Hodiny funguj\u00fa bu\u010f v 24-hodinovom form\u00e1te alebo v p\u00e1sme \/ AM \/ PM v 12-hodinovom form\u00e1te.

Adresa a \u00fadaje sa pren\u00e1\u0161aj\u00fa s\u00e9riovo cez obojsmern\u00fa zbernicu I2C.
\nPresn\u00fd teplotne kompenzovan\u00fd referen\u010dn\u00fd a kompara\u010dn\u00fd obvod monitoruje stav VCC, aby zistil v\u00fdpadky nap\u00e1jania, poskytol resetovac\u00ed v\u00fdstup a v pr\u00edpade potreby automaticky prepol na z\u00e1lo\u017en\u00fd zdroj. Okrem toho je \/ RST pin monitorovan\u00fd ako manu\u00e1lne generovanie \u03bcP resetu.

Presnos\u0165 tohto teplotn\u00e9ho sn\u00edma\u010da je \u00b1 3 \u00b0C. Riadiaci obvod nap\u00e1jacieho zdroja na \u010dipe dok\u00e1\u017ee automaticky rozpozna\u0165 a spravova\u0165 hlavn\u00e9 a pohotovostn\u00e9 nap\u00e1janie (t.j. n\u00edzkonap\u00e4\u0165ov\u00fa bat\u00e9riu) na prep\u00ednanie medzi nap\u00e1jan\u00edm.
