General Description
The low-voltage serial-peripheral interface (SPI)
DS1390/DS1391 and the low-voltage 3-wire DS1392/
DS1393 real-time clocks (RTCs) are clocks/calendars
that provide hundredths of a second, seconds, min-
utes, hours, day, date, month, and year information.
The date at the end of the month 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.
One programmable time-of-day alarm is provided. A
temperature-compensated voltage reference monitors
the status of V
CC
and automatically switches to the
backup supply if a power failure is detected. On the
DS1390, a single open-drain output provides a CPU
interrupt or a square wave at one of four selectable fre-
quencies. The DS1391 replaces the SQW/
INT
pin with a
RST
output/debounced input.
The DS1390 and DS1391 are programmed serially
through an SPI-compatible, bidirectional bus. The
DS1392 and DS1393 communicate over a 3-wire serial
bus, and the extra pin is used for either a separate
interrupt pin or a
RST
output/debounced input.
All four devices are available in a 10-pin μSOP package,
and are rated over the industrial temperature range.
