DS1307Z+
Analog DevicesDS1307Z+ is the SOIC-8 variant of the classic DS1307 I2C real-time clock from Analog Devices (Maxim), pairing a seconds-to-year calendar with 56 bytes of battery-backed NV SRAM on a 4.5 V to 5.5 V supply. Battery backup current below 500 nA keeps a coin cell alive for years, the programmable square-wave output covers auxiliary clock duties, and leap-year compensation runs to 2100, which is why the part remains specified in metering, data logging and long-lived embedded boards. Selection advice: order the full DS1307Z+ code - the plus sign is the RoHS ordering mark and the un-suffixed DS1307Z is obsolete at ADI; the DIP-8 DS1307+ and the industrial-grade DS1307ZN+ on this site are the through-hole and extended-temperature alternatives, and the tape-and-reel code is DS1307Z+T&R. This commercial grade is rated 0 to 70 C. Parameters verified against the ADI DS1307 product page (data sheet Rev. 5, Production).
