#94564 - RTC problem |
Hi,
In my data logger system I am using pcf8583.There are other i2c devices like 24c64,pcf 8574 also interfaced on i2c bus to 89c52. There is battery backup to pcf8583. The system works fine. But I find after few days the date & time gets corrupted & then it becomes difficult to rewrite the date/time again, Unless I remove the ic from socket and put it in the socket again. What may be the problem. |
