The DS1302 trickle-charge timing chip has a real-time clock / calendar and 31 bytes of SRAM. The chip communicates with the microprocessor via a simple serial interface. The real-time clock / calendar shows the seconds, minutes, hours, days, the date, the month and the year. The number of days in a month is determined automatically, including that of a leap month. The clock works in 24-hour format or in 12-hour format with an AM / PM indicator.

Characteristics

  • manage all timekeeping functions: real time clock counts, minutes, date, month, month, day, week, and year with leap year
  • 31 x 8 battery-backed general-purpose RAM
  • simple serial port interfaces to most microcontrollers: simple 3-wire interface
  • TTL compatible: VCC = 5 V
  • single-byte or multiple-byte (burst mode) data transfer for read or write or clock or RAM data
  • low power operation extends battery backup run time: 2.0 V to 5.5 V full operation
  • uses less than 300 nA at 2.0 V
  • temperature range: 0 ° C to + 70 ° C
