RTC DS1302 Real Time Clock Module with battery Digital Clock Module For AVR ARM PIC SMD for Uno 

Specification: 

1 simple 3-wire interface
2 Vcc = 5V and TTL-compatible
3 Optional industrial temperature range -40 to +85
4 Dual power tube for the main power and backup power supply 
5 Wide range of operating voltage 2.0 5.5V 
6 Current 2.0V, less than 300nA 
7 31 8 temporary data storage RAM 
8 Serial I / O port pin makes the least number of ways 
9 Read / write clock or RAM data transmission when there are two single-byte transmit and multi-byte      character sets transfer mode 
10 8-pin DIP package or optional 8-pin SOIC package assembly according to the surface 
Size : 44mmX23mmX1.6mm / 1.7''X0.9''/0.06'' ( approach ) 
Working Temperature: 0°~+70° 
Operating Voltage Range:3.3v ~ 5V 
Note : Do not reverse VCC and GND, will it cause damage
It requires a pull-up resistor for P0 port of 51 MCU, if without, you can connect the data cable to other terminal
