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 auto-
matically 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)
