Thanks The one on CCS's examples is for the DS1302, which has a 3-wire bus, compared to the DS1307Z with a 2-wire bus. DS1307Z replaces the former DS1307. It's still the same device and withsame functions.

Is that the real time clock. I think I fried my DS1307 when I put 5 volts to the battery input instead of battery voltage approx. 3 volts. It would not oscillate the clock after that. I got a DS1629 part which has temperature and clock, and got that to work with CCS C compiler. I think the same code would work. Dallas combined the DS1307 clock and the DS1621 chips into one DS1629. Only problem I had was that it only comes as an SMD part.

The DS1307Z Datasheet says +5V for Vcc and max. +3B for Vbatt. It runs without Vbatt, but not without Vcc. You are right, The DS1629 uses the same protokol (2-wire bus).

>From the DS1307/DS1308 datasheet the suffix's are; DS1307 8-pin DIP DS1307Z 8-pin SOIC (150-mil) DS1307N 8-pin DIP (IND) DS1307ZN 8-pin SOIC (IND) DS1308 36-pin BGA DS1308N 36-pin BGA (IND) I was unable to find the DS1307 or DS1307N at Newark. Are they available elsewhere? Thanks Bruce Holmen >Peter Keller wrote: >> >> Hi >> is there anybody who has programmed the RTC DS1307Z in C ? >> Peter > >The CCS has a example!!! It works fine!!!
