  • Feature:
    DALLAS DS1302 is 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
  • Wiring methods (procedures in order to provide an example, you can access any IO port, modify the port definition in the program can be):
    VCC +5 V/3.3V
    GND GND
    CLK P02
    DAT P01
    RST P00
     
  • Color: show as pictures
    PLS NOTE that due to lighting effects, monitor's brightness / contrast settings etc, there could be some slight differences in the color tone of the pictures and the actual item! 

    Note:
    1. VCC and GND Do not reversed, it would burn the chip
    2. C51 MCU P0 port requires pull-up resistor, if your device does not have a pull-up resistor you can connect it to other ports data lines
