Description
The DS1390/DS1391/DS1394 and DS1392/DS1393 are real-time clocks (RTCs) that provide time and date information, including hundredths of a second, seconds, minutes, hours, day, date, month, and year. They automatically adjust for months with fewer than 31 days and leap years. The clocks operate in either 24-hour or 12-hour format with an AM/PM indicator. They also feature a programmable time-of-day alarm.
Features
Reset output/debounced input (DS1391/DS1393)
Separate SQW and INT output (DS1392)
Trickle-charge capability
SPI support (DS1394: modes 0 and 2; DS1390/DS1391: modes 1 and 3)
3-wire interface (DS1392/DS1393)
Operating voltages: 1.8V ±5%, 3.0V ±10%, and 2.97 to 5.5V (DS1394: 3.3V ±10%)
Industrial temperature range: -40°C to 85°C
Underwriters Laboratories (UL) recognized
Applications
Hand-held devices
GPS/telematics devices
Embedded time stamping
Medical devices
