DS1302 Real Time Clock RTC Module

Between the microcontroller and DS1302 can simply use the synchronous serial communication way, just use three port lines:
(1) RST Reset
(2) I / O data lines
(3) SCLK Serial Clock.
Clock / RAM read / write data up to a 31-byte or byte character set mode of communication.
DS1302 low power consumption while working to keep the data and clock information power of less than 1mW.

DS1302 key performance indicators:
1) Real-time clock with before 2100 can be calculated in seconds, minutes, hours, days, weeks, months, years of capacity, as well as the ability to leap year adjustment
2) 31 * 8 bit temporary data storage RAM
3) Serial I / O ports such a way that a minimum number of pins
4) Wide range of operating voltage: 2.0-5.5V
5) When operating current 2.0V, less than 300nA
6) Simple 3-wire interface
7) Compatible with TTL Vcc = 5V
8) Optional industrial temperature range : -40 to +85 degree
9) Dual power tubes used for the main power supply and backup power supply
10) Read / write clock or RAM data There are two ways to send single-byte and multi-byte transmit burst transfer mode

Wiring Method (supplied with the program, can be connected to any IO port, modify the
port can be defined in the program):

VCC → +5 V/3.3V
CLK → P02
DAT → P01
RST → P00
