  • The STSAFE-TPM (trusted platform module) family of products offers a broad portfolio of standardized solutions for embedded, PC, mobile and 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 are all Common Criteria (EAL4+) and FIPS certified.
    They embed an Arm® SecurCore SC300™ processor with additional security features to help protect against advanced forms of attack.
    The ST33TPHF2ESPI offers a slave serial peripheral interface (SPI) compliant with the TCG PC Client TPM Profile specifications.
    The ST33TPHF2ESPI supports two exclusive modes that support either TPM 1.2 or TPM 2.0 commands. The product can be locked irreversibly in TPM 1.2 or TPM 2.0 mode during provisioning, or only after provisioning to provide a smooth migration between TPM 1.2 and TPM 2.0.
    The ST33TPHF2ESPI operates in the –25 to +85 °C commercial temperature range with a supply and I/O voltage of 1.8 V, or in the –40 °C to 105 °C extended temperature range with a supply and I/O voltage of 3.3 V.
    The device is offered in TSSOP28 and VFQFPN32 ECOPACK2 packages. ECOPACK is an ST trademark.
