Default I2C address of ST33KTPM2X

Hi,

 

In the ST33KTPM2X datasheet is mentioned that the I2C device address is configurable in the range of 0x08 to 0x77, but what is its default after power-up ... it is not mentioned in the datasheet. A STSafe application note suggests 0x2E, is that correct?

 

Thanks,

Bert

    Hi @LMaarsen,

    Thanks Bert for your interest in STSAFE-TPM product.

    The I2C address is defined by TCG within the PTP specification and yes this is 0x2E on 7bits.

    Best Regards,

    Benjamin
