Engineering Brief
The ST33TPHF2XI2C is a flash-based Trusted Platform Module (TPM 2.0) security controller from STMicroelectronics featuring dual-interface capability with both NFC contactless (13.56 MHz ISO 14443-A) and I²C wired connectivity. It integrates 2 MB of Flash memory and comprehensive cryptographic accelerators supporting AES-256, RSA-2048, and ECC-256 with Common Criteria EAL5+ certification. The dual-interface design enables traditional TPM functions via I²C while supporting contactless NFC operations for secure provisioning, authentication, and diagnostics, making it ideal for modern secure computing platforms requiring both trusted boot capabilities and flexible NFC-based management.
Typical Applications
- Trusted Platform Module for PC and embedded systems
- Secure boot and firmware attestation
- Cryptographic key storage and management
- NFC-enabled device authentication
- IoT device security and provisioning
- Contactless configuration and diagnostics
