TCG TPM I2C Interface Specification


The Trusted Computing Group TPM I2C Interface Specification is an industry specification that defines an I2C Interface for TPM 2.0.

As this specification defines only the interface for the I2C-TPM a suitable platform specification must be considered additionally to allow the design of a platform specific I2C-TPM. It is expected that the reader of this specification is familiar with the PTP [2].

This specification is intended for a single TPM on an I2C bus. It does not address multiple TPMs on the same I2C bus.
