Dear members,
I built a chematik with AT89S52, with RTC (DS1302).
With normal quarz it is not very accurat (20ppm).
Better is DS32kHz from DALLAS (2ppm – 1 minute/year).
I buyed some in China (Jacky leePower Start ElectronICs1504Room,16buildingChangcheng Garden,Baihua 5 Road,Futian District Shenzhen,ChinaTel: 00-86-755-81531771 Fax: 00-86-755-83217755) and they sent me some units DS32kHz - but with 8 pins in SMD (SMD is ok.).

I don’t know the connection (8pin SMD). Can you help me please.
The datasheets (SO-16pin, EDIP-14pin and BGA-36pin) I have.

With regards
