div style="color: #000000;font-family: arial;"> DS1302 real time clock module DALLAS DS1302 is the company launched a trickle charge the clock chip , which contains a real-time clock / calendar and 31 bytes of static RAM, communicate via a simple serial interface with the microcontroller . Real-time clock / calendar circuit provides seconds , minutes, hours , days, weeks, months , years of information , the number of days per month and days can be automatically adjusted for leap year . Clock operation may indicate decided to use 24 or 12-hour format by AM / PM. Between the DS1302 can simply use synchronous serial microcontroller way to communicate , 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: 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 31 8 temporary data storage RAM Serial I / O ports such a way that a minimum number of pins Wide range of operating voltage 2.0 5.5V When operating current 2.0V, less than 300nA Read / There are two ways to send single-byte and multi-byte transfer mode transmission character set data write clock or RAM 8-pin DIP or optional 8- pin SOIC surface mount package according to Simple 3-wire interface Compatible with TTL Vcc = 5V Optional industrial temperature range of -40 to +85 Dual power tube for the main power supply and backup power supply DS1302 real time clock module parameters are as follows : 1.PCB single panel size : 44mm * 23mm * 1.6mm 2 with four positioning holes , 3.1mm in diameter 3 backup battery is genuine celestial CR2032, voltage 3V, current 260mAh, non- rechargeable batteries. Theoretical data hold time is more than 10 years ! 4 Crystal 32.768KHz, Japan imported crystal, matching capacitance 6pF, size 2 * 6mm 5.DS1302 made large 8-pin DIP chips, IC chips below seat , easy to replace and swap chips 6 module operating voltage compatible 3.3V/5V, can be connected to 5V and 3.3V microcontroller 7 Working temperature :. 0 ° --- 70 ° Wiring ( supplied with the program , for example, can be connected to any IO port, modify the port can be defined in the program ) : VCC → +5 V/3.3V GND → GND CLK → P02 DAT → P01 RST → P00 Note: 1.VCC and GND Do not reversed , it would burn the chip 2.51 MCU P0 port requires pull-up resistor , if your device does not have a pull-up resistor can be connected to other ports data lines Shipping list : 1.DS1302 a real-time clock module (with DS1302 chip and spare batteries, a good functional test before shipment ) If need more parts Pls click ,and submit the order ,if some parts can not find out in my store .Pls contact us.we still have many parts don\'t published. Payment Method: We accept Escrow service and so one. Notes: Seller don’t responsible for the import duty and cutoms fee. All order Feedback is important to our store.
