New Arduino RTC DS1302 Real Time Clock Module For AVR ARM PIC SMD

DS1302 real time clock module

DALLAS DS1302 is the company launched trickle charge the clock chip, which contains a real-time clock / calendar and 31 bytes of static RAM, via a simple serial interface to communicate with the microcontroller. Real-time clock / calendar circuit provides seconds, minutes, hours, days, weeks, months, years of information, the number of days per month and leap year automatically adjust the number of days. Clock operation by AM / PM indicator decided to use 24 or 12 hour format. DS1302 between the microcontroller can simply adopt the way synchronous serial communication port only used three lines: (1) RST Reset (2) I / O data lines (3) SCLK Serial Clock. Clock / RAM read / write data in a byte or up to 31 bytes of character set type communication. DS1302 work to maintain low power consumption data and clock information when power is less than 1mW

DS1302 Features:

  • Real-time clock with energy calculations before 2100 seconds, minutes, hours, day, week, month, year capacity, as well as the ability to leap year adjustment.
  • Wide operating voltage range 2.0 5.5V
  • 2.0V, operating current of less than 300nA
  • read / write clock or RAM data transfer mode, there are two single-byte and multi-byte transfer mode transmission character set
  • 8-pin DIP package or an optional 8-pin SOIC surface mount package under
  • simple 3-wire interface
  •  Vcc = 5V and TTL compatible
