The real-time clock / calendar circuit provides seconds, minutes, and information of days, weeks, months, years, the number of days the number of days per month and leap year can automatically adjust. Clock operation can be used to indicate the decision by the AM/PM 24 or 12 hour format. DS1302 and microcontroller can simply use the synchronous serial communication, only need to three ports: (1) RST reset (2) I/O data line (3) SCLK serial clock. /RAM clock read / write data to a group of characters or bytes up to 31 bytes of communication. When DS1302 is working, low power consumption to maintain data and clock information when the power is less than 1mW Main performance index of DS1302: Real-time clock can be calculated before 2100 seconds, minutes, time, day, week, month, year and leap year adjustment ability 318 temporary data storage RAM I/O serial port makes the minimum number of pins Wide range working voltage 2 5.5V Operating current 2.0V, less than 300nA Read / write clock or RAM data, there are two kinds of transmission mode single byte transfer and multi byte transfer character group 8 pin DIP package or optional 8 pin SOIC package according to surface mount Simple 3 wire interface Compatible with Vcc=5V TTL Optional industrial grade temperature range +85 -40 Dual supply tube for main power supply and backup power supply DS1302 real time clock module parameters are as follows: 1.PCB for single panel, size: 44mm*23mm*1.6mm 2 with 4 positioning holes, diameter 3.1mm 3 spare battery for genuine celestial CR2032, voltage 3V, current 260mAh, non rechargeable batteries.
