DS1302 Clock Module with Battery Real-Time Clock Module RTC for Arduino AVR ARM
DS1302 real time clock module
DALLAS DS1302 is the company launched trickle charge the clock chip, which contains a real-time clock / calendar and 31 bytes of static RAM.
via a simple serial interface to communicate 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 leap year automatically adjust the number of days.
Clock operation by AM / PM indicator decided to use 24 or 12 hour format. DS1302 between the microcontroller can simply adopt the way synchronous serial communication port only used three lines: (1) RST Reset (2) I / O data lines (3) SCLK Serial Clock. Clock / RAM read / write data in a byte or up to 31 bytes of character set type communication. DS1302 work to maintain low power consumption data and clock information when power is less than 1mW
DS1302 key performance indicators:
Real-time clock with energy calculations before 2100 seconds, minutes, hours, day, week, month, year capacity, as well as the ability to leap year adjustment
serial I / O ports such a way that a minimum number of pins
Wide operating voltage range 2.0 5.5V
2.0V, operating current of less than 300nA
Read / write clock or RAM data transfer mode, there are two single-byte and multi-byte transfer mode transmission character set
8-pin DIP package or an optional 8-pin SOIC surface mount package under
Simple 3-wire interface
Vcc = 5V and TTL compatible
Optional industrial temperature range of -40 to +85
Dual power tubes used for the main power supply and backup power supply
DS1302 real time clock module parameters are as follows:
PCB single panel, size: 44mm * 23mm * 1.6mm
With four positioning holes, diameter 3.1mm
Backup battery is genuine celestial CR2032, Voltage 3V, current 260mAh, non-rechargeable batteries.
Crystal 32.768KHz, Japan imported crystal, matching capacitance 6pF, size 2 * 6mm
DS1302 is made large 8-pin DIP chip, chip below IC socket for easy replacement and swap chips
Module operating voltage compatible 3.3V/5V, can be connected with 5V and 3.3V microcontroller
Working temperature: 0degree--- 70degree
4.3x 2.3cm
Package included:
1x DS1302 Module
1x CR2032 battery
Note: Light shooting and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
