  • The ST33TPHF2EI2C is a cost-effective and high-performance Trusted Platform Module (TPM) targeting PC, server platforms and embedded systems.

    This product supports two modes exclusively: TPM 1.2 mode and TPM 2.0 mode. In TPM 1.2 mode, the set of TPM 1.2 commands is supported and only TPM 1.2 assets can be accessed. In TPM 2.0 mode, the set of TPM 2.0 commands is supported and only TPM 2.0 assets can be accessed.
    In TPM 1.2 mode, the product implements the functions defined by the Trusted Computing Group in the TCG Trusted Platform Module Specifications version 1.2 Level 2 Revision 116, and is also based on the TCG PC Client specific TPM interface specifications 1.3.
    In TPM 2.0 mode, the product implements the functions defined by the Trusted Computing Group in the TCG Trusted Platform Module Library Specifications version 2.0 Level 0 Revision 138 and errata version 1.3. It is also based on the TCG PC client-specific TPM Platform specifications rev 1.03 and errata sheet.
    The product also supports the ability to upgrade the TPM firmware thanks to a persistent application Flash loader to support new standard evolutions.
    This product is CC certified according to TPM 1.2 and TPM 2.0 at EAL4+.
    It obtained FIPS 140-2 level 1 certification for both modes and level 2 for mode TPM2.0.
