DS1338
I
2
C RTC with 56-Byte NV RAM
GENERAL DESCRIPTION
The DS1338 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 I
2
C
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
AM/PM indicator. The DS1338 has a built-in power-
sense circuit that detects power failures and
automatically switches to the backup supply,
maintaining time and date operation
BENEFITS AND FEATURES
Completely Manages All Timekeeping
Functions
o
RTC Counts Seconds, Minutes, Hours,
Date of the Month, Month, Day of the
Week, and Year with Leap-Year
Compensation Valid Up to 2100
o
