[FAQ] Running I2C in Standard Mode (100kHz)

Gage Farmer

Part Number: TMP103

Hello Team,

Regarding the TMP sensor family, are they able to run at 100kHz as named ‘Standard Mode’ in the I2C standard? If so, are all the sensor specifications compatible with the I2C standard?

All of our I2C devices support the use of Standard Mode at the speed of 100kHz with no issue, as described in the Philips/NXP I2C Specification. While this is not covered in the datasheet, for some devices there will be a mention of <100kHz speeds at the bottom of the Timing Requirements table, and what change on the device that will have.

The following threads address this question further.
TMP110: 100kHz I2C standard check
TMP103 I2C timing for Standard Mode
TMP102: I2C Rise Time Spec
TMP1075: I2C SDA/SCL Rising time during 100khz application

Best,
Gage
