Part Number: TMP75C-Q1

Dear support team;

At initial, we want to write the threshold value by MCU.

Is there any wait time from power on reset to serial bus access?

If we need it, how many time do we have to wait?

Best Regards,

Hi Sugiyama-san,

The device will be ready to communicate as soon as the Vs pin reaches a steady, valid supply voltage. The first temperature result will be available to be read approximately 30ms (Conversion Time) after power-on. If you want to specify a wait regardless, anything longer than 30ms would be excessive.

Thanks,
Ren
