Product Overview
The DS1392U-33+ is a low voltage 3-wire real time clock (RTC) with trickle charger in 10 pin µSOP package. It has typical operating voltage of 3.3V. This clock/calendar provides hundredths of seconds, 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 leap year compensation valid up to 2100. The clock operates in either 24hour or 12hour 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 bus interface and switches to backup supply if a power failure is detected. The DS1392 communicates over a 3-wire serial bus and the extra pin is used for either separate interrupt pin or complementary RST output/debounced input. It is used in GPS/telematics devices, embedded time stamping applications.
- Supply voltage range from 2.97V to 5.5V

- Power fail detect and switch circuitry
- Separate SQW and INT output
- SCLK frequency of 4MHz ( 2.7V ≤ VCC ≤ 5.5V)
- UL recognized
- VCC active supply current of 2mA and VCC standby current of 115μA
- Time keeping current of 500nA
