Main Performance Indicators:
★ Real-time clock can be calculated before 2100 seconds, minute, hour, day, week, month, year capacity, as well as leap year adjustment capacity
★ 31 8-bit temporary data storage RAM
★ Serial I / O port, making the least number of pins
★ Wide range of operating voltage 2.0 5.5V
★ Operating Current 2.0V, less than 300nA
★ Read / write clock or RAM data when there are two kinds of transmission mode in a single byte transfer and multi-byte the transmitted character group way
★ 8-pin DIP package or an optional 8-pin SOIC package surface mount
★ Simple 3-wire interface
★ VCC = 5V TTL compatible
★ Optional industrial temperature range of -40 to +85
★ Gual supply pipe for the main power and backup power supply

Module Parameters:
★ PCB single panel size: 44 x 23 x 1.6 mm
★ with four positioning holes, diameter 3.1mm
★ Spare batteries the genuine celestial CR2032 Voltage 3V, current 260mAh, non-rechargeable batteries. The theoretical data retention time is more than 10 years
★ Crystal 32.768KHz, Japan imported crystal, matching capacitance 6pF, and size 2 x 6mm
★ DS1302 8-pin DIP made large chip, chip below IC sockets for easy replacement and plug chip 6 module operating voltage compatible 3.3V/5V, can be connected with 5V and 3.3V microcontroller
★ Operating Temperature: 0 Deg.C ~ 70 Deg.C

Wiring Methods (provided by the program, for example, you can pick any IO port, port definition can be modified in the program):
VCC → + 5V / 3.3V GND → GND CLK → P02 DAT → P01 RST → P00

Note: The 1.VCC to GND Do not reversed, it would burn the chip 2.51 MCU P0 port pull-up resistor, if your microcontroller does not have pull-up resistor, data lines connected to other ports
