General Description
The DS1347 SPI-compatible real-time clock (RTC) con-
tains a real-time clock/calendar and 31 x 8 bits of static
random-access memory (SRAM). The real-time
clock/calendar provides seconds, minutes, hours, day,
date, month, year, and century information. A time/date
programmable polled ALARM is included in the device.
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 24hr or
12hr format with an AM/PM indicator. The device oper-
ates with a supply voltage of +2V to +5.5V, are avail-
able in the ultra-small 8-pin TDFN package, and work
over the -40°C to +85°C industrial temperature range.
