Confusing. I have an old copy of the datasheet, from 2004, version 0.3. I suspect that the 2007 document is simply a reformatted copy of the 2004 document to comply with the layout of the day at SMSC. Which means that SMSC apparently "lost" the 0.4 version from 2005. Might as well have been on purpose if Guenter is right and revision A2 of the chip became the EMC6D103S. Anyway, I hope SMSC are better at designing and implementing chips than at handling documents and deciding names ;) > On the other side, SMSC also has the datasheet for EMC6D103S with ID 0x6a > on their web site.

It's really difficult to tell from the datasheets. Jan, maybe you could try to take a look at the device physically to see how it is labelled? -- Jean Delvare _______________________________________________ lm-sensors mailing list lm-sensors@xxxxxxxxxxxxxx http://lists.lm-sensors.org/mailman/listinfo/lm-sensors
