Low-Voltage SPI/3-Wire RTCs with  
Trickle Charger  
General Description  
Features  
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  
♦ Real-Time Clock Counts Hundredths of Seconds,  
Seconds, Minutes, Hours, Day, Date, Month, and  
Year with Leap-Year Compensation Valid Up to  
2100  
♦ Output Pin Configurable as Interrupt or Square  
Wave with Programmable Frequency of  
32.768kHz, 8.192kHz, 4.096kHz, or 1Hz  
(DS1390/DS1393 Only)  
♦ One Time-of-Day Alarm  
♦ Power-Fail Detect and Switch Circuitry  
♦ Reset Output/Debounced Input (DS1391/DS1393)  
♦ Separate SQW and INT Output (DS1392)  
♦ Trickle-Charge Capability  
the status of V  
and automatically switches to the  
CC  
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.  
♦ SPI Supports Modes 1 and 3 (DS1390/DS1391)  
♦ 3-Wire Interface (DS1392/DS1393)  
♦ 4MHz at 3.0V and 3.3V  
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.  
♦ 1MHz at 1.8V  
♦ Three Operating Voltages: 1.8V ±±5, 3.0V ±105,  
All four devices are available in a 10-pin µSOP package,  
and are rated over the industrial temperature range.  
and 2.97 to ±.±V  
♦ Industrial Temperature Range: -40°C to +8±°C  
♦ Underwriters Laboratory (UL) Recognized
