DS1308 Low-Current I2C RTC with 56-Byte NV RAM General Description The DS1308 serial real-time clock (RTC) is a low-power, full binary-coded decimal (BCD) clock/calendar plus 56 bytes of NV RAM. Address and data are transferred serially through an I2C interface. 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 operate.

Low-Current I2C RTC

DS1308 Low-Current I2C RTC with 56-Byte NV RAM General Description The DS1308 serial real-time clock (RTC) is a low-power, full binary-coded decimal (BCD) clock/calendar plus 56 bytes of NV RAM. Address and data are transferred serially through an I2C interface. 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 an AM/PM indicator. The DS1308 has a built-in power-sense circuit that detects power failures and automatically switches to the backup supply, maintaining time and date operation. Applications Handhelds (GPS, POS Terminal) Consumer Electronics (Set-Top Box, Digital Recording, Network Appliance) Office Equipment (Fax/Printer, Copier) Medical (Glucometer, Medicine Dispenser) Telecommunications (Router, Switcher, Server) Other (Utility Meter, Vending Machine, Thermostat, Modem) Benefits and Features ●● Compatible with Crystal ESR Up to 100kΩ Allows a Crystal to be Optimized for Cost and Space ●● Low-Power Operation Extends Battery Backup Run Time • Low Timekeeping Current of 250nA (typ) • Automatic Power-Fail Detect and Switch Circuitry ●● Completely Manages All Timekeeping Functions • Real-Time Clock Counts Seconds, Minutes, Hours, Date of the Month, Month, Day of the Week, and Year with Leap-Year Compensation Valid Up to 2400 • Externa.
