Hai,

How to enable the clock output for RTC(8563) interfacing with 89C52.

I need the coding for this.Please give suggestion.



Thanks in Advance
 

RTC 8563 uses I2C and 8051 doesn't have hardware I2C. You have to write software I2C code and use it to read and write RTC.
 

A working mikroC PRO 8051 code for RTC 8563 using Software I2C is attached. See Proteus simulation video inside .rar file.

For tuning the crystal oscillator to get +/-1 sec per day. to get the clock output of about 1khz or 32.768khz
 

Automatic timer is our application.We required 32.768KHZ frequency,+/-1ppm.We don't know the load capacitance
