DS1394U-33+T&R

The DS1394U-33+T&R is a low-voltage, SPI RTC with trickle charger in 10 pin μSOP package. This real-time clock (RTC) is a clock/calendar 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 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 the bus interface and switches to the backup supply if a power failure is detected. Typical applications include hand-held devices, GPS/telematics devices, embedded time stamping and medical devices.
