Hot-selling and scarce DS1307Z+ 64 x 8, Serial, I2C Real-Time Clock SOP8 spot stock

Product Descriptions

The DS1307 serial real-time clock (RTC) is a  low-power, full binary-coded decimal (BCD)  clock/calendar plus 56 bytes of NV SRAM.  Address and data are transferred serially through  an I2 C, bidirectional bus. The clock/calendar  provides seconds, minutes, hours, day, date,  month, and year information. The end of the  month date is automatically adjusted for months  with fewer than 31 days, including corrections for  leap year. The clock operates in either the 24- hour or 12-hour format with AM/PM indicator.  The DS1307 has a built-in power-sense circuit  that detects power failures and automatically  switches to the backup supply. Timekeeping  operation continues while the part operates from  the backup supply.
