TMP75: TMP75 I2C

Part Number: TMP75

Hello Team,

We only define I2C timing requirement for fast and high-speed mode in TMP75 datasheet, Can our part work in standard I2C mode? If yes, what's the timing requirement? Thanks

Regards,

Nanfang

    Yes, we support Standard Mode as defined in the NXP I2C Spec. Most of this spec is repeated in our datasheet, but formatted in a different way. This is because our device only acts as a Slave, so not all of the parameters are relevant.

    I2C does not have a minimum frequency. Our minimum frequency is indirectly set by our Time-out feature. If you do not complete the I2C Transaction (defined as the time from START to STOP) within 30ms, the device will time-out and reset the interface. This Time-out is a requirement of SMBus that does not exist in the I2C specifcation.
