New RTC DS1302 Real Time Clock Module

Module voltage compatible with 3.3V / 5V, can be connected to 3.3V or 5V SCM

• 3v 260mAh backup battery(not rechargeable batteries)
• Crystal oscillator 32.768KHz
• Working temperature 0°C to 70°C
• 4 positioning holes, diameter 3.1mm
• Size: 44 x 23 x 1.6mm

Feature:

The real time clock has the ability of calculating prior to the 2100 second, minute, hour, day, week, month, year, and the ability to adjust a leap year

• 31 8 temporary data storage RAM
• Serial I / O port pin makes the least number of ways Wide range of operating voltage 2.0V - 5.5V
• When The working voltage is 2.0V, the current is less than 300nA
• Read/write clock or RAM data have two transmission way: Single-byte / many bytes group
• 8 feet DIP assembly or optional 8 feet SOIC encapsulation according to surface assembly
• Simple 3 line interface
• Optional industrial temperature range -40°C to +85°C
• Dual power tube for the main power and backup power supply
• TL compatible(Vcc = 5V)

Note:
Do not reverse VCC and GND, it will 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.
