ST’s STSAFE-TPM cryptographic modules for PCs, servers, and embedded systems are among the first to receive FIPS 140-3 certification. These Trusted Platform Modules (TPMs) protect sensitive data by securely managing cryptographic keys and operations, ensuring compliance with security and regulatory requirements for critical information systems.

FIPS 140-3 is the most recent Federal Information Processing Standard (FIPS) for cryptographic modules, superseding FIPS 140-2. It defines four security levels to address various applications and environments, covering secure design, implementation, and operation. FIPS 140-2 certificates expire in September 2026.
The newly certified TPMs include the ST33KTPM2X, ST33KTPM2XSPI, ST33KTPM2XI2C, ST33KTPM2I, and ST33KTPM2A. The ST33KTPM2I is qualified for long lifetime industrial systems, while the ST33KTPM2A leverages an AEC-Q100 qualified hardware platform required for automotive integration.
STSAFE-TPM devices comply with multiple security standards, including Trusted Computing Group TPM 2.0, Common Criteria EAL4+ (AVA_VAN.5), and FIPS 140-3 level 1 with physical security level 3. They provide cryptographic services—including ECDSA, ECDH (up to 384 bits), RSA (up to 4096 bits), AES (up to 256 bits), and SHA1, SHA2, and SHA3—all standardized by TCG and compatible with FIPS 140-3-certified software stacks.
ST also offers provisioning services to load device keys and certificates, speeding time to market and ensuring supply chain security.
