Description:

The DS1302 RTC Module works very much like a watch. The DS1302 RTC Module accurately keeps time with a precise oscillator and is maintained with a small battery (not included). DS1302 RTC Module is used to give an accurate date and time in many applications. The DS1302 RTC Module is ideal in any time-critical applications like attendance systems, digital cameras, automated sprinkler systems, or a time and calendar display.

Features:

• The real-time clock counts minutes, seconds, dates, hours, month day of the week, year and leap-year compensation up to 2100.
• 318 temporary data storage RAM
• Working current of 2.0V, less than 300nA
• Read / Write clock or RAM data with two kinds of modes single-byte transfer mode and multi-byte character set
• 8 pin DIP package or optional 8-pin SOIC package based on the surface assembly
• Simple 3-wire interface
• Compatible with TTL Vcc=5V
• Double power supply pipe for main power and backup power supply.

Pin Description:

• VCC2 +5 V/3.3V
• GND GND
• CLK P02
• DAT P01
• RST P00

Note:

• VCC and GND do not reverse, so as not to burn the chip
• 51 SCM P0 port to receive a pull-up resistor, if your computer is not connected pull-up resistor, the data can be the string to the other port.
