The low-voltage serial-peripheral interface (SPI?)

DS1390/DS1391/DS1394 and_the low-voltage 3-wire

DS1392/DS1393 real-time clocks (RTCs) are clocks/

calendars that provide hundredths of a second, seconds,

minutes, 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 VCC

and_automatically disables the bus interface and_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 frequencies. The DS1391 replaces the SQW/INT pin with a RST

output/debounced input.

The DS1390, DS1391, and_DS1394 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 five devices are available in a 10-pin μSOP package,

and_are rated over the industrial temperature range.
