The ST33GTPMAI2C is a cost-effective and high-performance trusted platform module (TPM) targeting automotive 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 and errata version 1.4. It is also based on the TCG PC client-specific TPM Platform specifications rev1.03. The applicable protection profile is TCG Protection Profile for PC Client Specific TPM 2.0.


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