DS1302 RTC

0.900 د.ك

The real-time clock/calendar circuit provides seconds, minutes, hours, days, weeks, months, and years of information. The number of days in a month and days in a leap year can be adjusted automatically. Clock operation can be decided by AM/PM instruction in 24 or 12 hour format.Only three lines are required: (1) RST reset (2) I/O data line (3) SCLK serial clock. Clock/RAM read/write data is communicated in one-byte or up to 31-byte character groups. When DS1302 is working, the power consumption is very low. When the data and clock information are kept, the power is less than 1mW.

 

VCC→+5V/3.3V

GND→GND

CLK→P02

DAT→P01

RST→P00

Precautions:

1. VCC and GND must not be reversed to avoid burning the chip

2.51 MCU P0 port needs to be connected with pull-up resistor. If your MCU is not connected with pull-up resistor, you can connect the data cable to other ports
