HDC2080: I2C Interface Timing Requirements

Hiroshi Katagiri
Prodigy 30 points
Part Number: HDC2080

There is no description of Tsu/Th in the data sheet.

Please tell me the following.

1.SDA Setup TIme

2.SDA Hold Time (SDA valid after SCL low)

When measuring the waveform at the time of I2C write, SDA Hold TIme was 125ns. 

Is there no problem?

Best regards,

Hiroshi

    Dear Hiroshi -
    Thanks for the feedback - in looking at other I2C specs we have and drawing from personal experience - I would think the SDA setup time is most likely 250nSec or greater and the SDA hold time must always be greater than 0, so 125nSec is acceptable.
