Product overview


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

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.

These 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 all Common Criteria (EAL4+) and FIPS certifications.

The STSAFE-V100-TPM is also referenced as ST33KTPM2A in CC and FIPS certification documents.

The STSAFE-V100-TPM, by default, offer two exclusive configurations:

  • a slave serial peripheral interface (SPI)
  • a slave I²C interface.

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

The STSAFE-V100-TPM operates in the –40 °C to 105 °C extended temperature range.

The STSAFE-V100-TPM devices are offered in Ecopack2 packages.

The STSAFE-V100-TPM devices are qualified AEC-Q100 grade 2 for automotive applications and are offered in TCG standardized UFQFPN32 wettable flanks and TSSOP20 packages.
