Just want to save my time:
does anybody already has Atmel C code for XICOR 4K (512 x 8)
2-Wire Real Time Clock/Calendar with EEPROM X1226?

:evil:

Stay away from XICOR RTC chips. We have developed a board with the X1288 real time clock chip and implemented the TWI interface to the RTC. What we have found is that the TWI activity cause the RTC to loose time. We now use the PHZ output as a 100Hz freq. input to a timer, and written our own RTC code...

NOTE XICOR has be bought by INTERSIL
