DS1394 Datasheet Low-voltage Spi/3-wire Rtcs

Manufacturer: Maxim Integrated (now Analog Devices)

Overview: Click here for production status of specific part numbers. DS1390–DS1394 Low-Voltage SPI/3-Wire RTCs with Trickle Charger.

This datasheet includes multiple variants, all published together in a single manufacturer document.

General Description

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.

Key Features

  • 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/ DS1394 Only).
  • One Time-of-Day Alarm.
  • Power-Fail Detect and Switch Circuitry.
  • Reset Output/Debounced Input (DS1391/DS1393).
  • Separate SQW and INT Output (DS1392.
