Hi

Please tell me which does DS110DF410 support SMBUS Specification Version  "2.0" or "1.0" ? 

Best regards

    Hi Sugiyama-san,

    DS110DF410 supports SMBus Specification Version 2.0.

    Please note that all devices compliant with previous specification versions are compliant with Version 2.0, so DS110DF410 can technically also support Version 1.0. The reason to state support of Version 2.0 is that Version 2.0 introduces electrical specifications for high power applications, particularly in the case of using riser card add-ins.

    Please refer to p. 5 and p. 11-17 for more details (http://smbus.org/specs/smbus20.pdf).

    Regards,

    Michael

    Hi Michael-san,

    Could you please add the SMBus electrical specification to the DS110DF410 datasheet ?

    I unerstand the device supports SMBus 2.0, but I think the DS110DF410 supporting SMBus clock frequency range is MIN 100kHz, where SMBus 2.0 specification is MIN 10kHz.

    I want to avoid the user designing the SMBus outside the recommended operating clock range, clock frequency under 100kHz. 

    Best Regards,

    Hi Kawai-san,

    Thanks for the feedback. This will be discussed for the next revision of the datasheet.

    Regards,
