The ST33TPHF20I2C is a cost-effective and high-performance Trusted Platform Module (TPM) targeting PC, server platforms and embedded systems.


The product implements the functions defined by the Trusted Computing Group (www.trustedcomputinggroup.org) in the TCG Trusted Platform Module Library Specifications version 2.0 Level 0 Revision 138 ([TPM 2.0 P1 r138], [TPM 2.0 P2 r138], [TPM 2.0 P3 r138], [TPM 2.0 P4 r138]) and errata version 1.4 [TPM 2.0 rev138 Err .4]. It is also based on the TCG PC client-specific TPM Platform specifications rev 1.03 [PTP 2.0 r1.03] and [Errata sheet]. [TPM 2.0 PP] specifies the protection profile.


The product also supports the ability to upgrade the TPM firmware thanks to a persistent application Flash loader to support new standard evolutions.
