TMP75: Does TMP75AIDGKR Support SMBUS and MCTP?

Wayne Chen (Audio AE)

Part Number: TMP75

Hi Sirs,

The TMP75AIDGKR supports I2C/SMBus interface. Would you please advise the process to read temperature through MCTP command protocol?

Thank you and Best regards,

Dear Wayne -
From my perspective - the MCTP www.dmtf.org/.../DSP0256_1.0.0.pdf is between the host controller and the MCU driving the I2C/SMBus bus to the sensor. There is no direct connection - to me it looks like a HAL is required. You would need to manage encapsulation of the I2C/SMBus messages from that side. You would leverage section 7.5 in the datasheet to access the registers.
