Product overview


The STSAFE-TPM (trusted platform module) family of products offers a broad portfolio of standardized solutions for embedded, PC, mobile, and computing applications.

It includes turnkey products compliant with the Trusted Computing Group (TCG) standards that provide services to protect the confidentiality, integrity, and authenticity of information and devices.

The STSAFE-TPM devices are easy to integrate thanks to the variety of supported interfaces and the availability of TPM ecosystem software solutions.

The STSAFE-TPM devices target Common Criteria, TCG, and FIPS certifications.

The ST33KTPM2X offers a slave serial peripheral interface (SPI) or a target I²C interface, both compliant with the TCG PC Client TPM Profile specifications.

It offers resilience services during the TPM firmware upgrade process, and self-recovery of TPM firmware and critical data upon failure detection.

The ST33KTPM2X operates in the –40 °C to 105 °C extended temperature range.

The device is offered in the UFQFPN32 ECOPACK2 package. ECOPACK is an ST trademark.
