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.
Package Included:
1 x DS1302 RTC Module DS1302 Real Time Clock Module
