Advanced TPM security modules released by STMicro

STMicroelectronics has introduced two STSAFE trusted platform modules (TPMs), which provide inaccessible, unalterable hardware-based data storage for protecting system-authenticated data of network-connected devices from cyber attack. The STSAFE TPMs are based on the Trusted Computing Group’s (TCG’s) TPM 2.0 specification and support features such as storage of cryptographic algorithms and user hierarchies, with one of the devices, the ST33TPHF2ESPI supporting the earlier TPM 1.2 specification as well. The other, the ST33TPHF20SPI includes 110 kB worth of non-volatile memory, the most in the market for TPM sensitive data storage, STMicro says.

The STSAFE TPM modules leverage the ARM SecurCore SC3000 processor, equipped with anti-tamper, memory protection, and data watching measures, and come with RSA and ECC endorsement keys (EKs) that support authentication. Additional Globalsign-verified key certificates are also provided. Both the ST33TPHF2ESPI and ST33TPHF20SPI are Common Criteria (CC) EAL4+ and TCG-certified.

Both devices are available in TSSOP28 or QFN32 packages, and in production now. For more information, visit
