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

    DMDG DS1302
    Nice clock module. Good thing is that it can calculate leap year so you do not need to worry about that.It has soldered all the pins.
    Suggestion
    It could be smaller.
