Product overview


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 ( 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.
