#243: DS1302 RTC Real Time Clock Module

R17.53


The usage of Real Time Clocks are essential in any system that needs to accurately keep track of time or measure difference in time. Simply add a battery and the RTC module will start ticking accurately. Including the ability to incude leap-years into consideration.

DS1302 ( with battery ) is introduced trickle charge the clock chip, containing 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 can be done by the AM / PM or 12

   decided to use 24 hour format. Between the DS1302 and the microcontroller can simply use the synchronous serial communication mode, used

   only three port lines: (1) RST Reset (2) I / O data lines (3) SCLK serial clock. Clock / RAM read / write data to a byte or up to 31 bytes of character

   set way communication. DS1302 low-power work to maintain the data and clock information when power is less than 1mW

   Real time clock with the year 2100 to calculate the seconds, minutes, hours, days, weeks, months, years, the ability, as well as the ability to leap

   year adjustment

   1.31 8 temporary data storage RAM

   2.Serial I / O port pin makes the least number of ways

   3.Wide range of operating voltage 2.0 5.5V

   4.Current 2.0V, less than 300nA

   5.Read / write clock or RAM data transmission when there are two single-byte transmit and multi-byte character sets transfer mode

   6.8-pin DIP package or optional 8-pin SOIC package assembly according to the surface

   7.simple 3-wire interface

   8.Vcc = 5V and TTL-compatible

   9.Optional industrial temperature range -40 to +85

   10.Dual power tube for the main power and backup power supply
