Overview

Product details

    The XL1307 Serial Real-Time Clock (RTC) is a low-power, all-binary-coded decimal (BCD) clock/calendar with 56 bytes of NV SRAM. Addresses and data are transmitted in serial via the l²C bidirectional bus. Clock/calendar provides seconds, minutes, hours, days, days, months, and years. For months with fewer than 31 days, the end date is automatically adjusted, including corrections for leap years. Clocks work in 24 hour or 12 hour format with AM. PM indicator. The XL1307 has a tilted power sensing circuit that detects a power failure and automatically switches to a backup power supply. The timing operation continues when the component is working through the backup power supply.
