Frequently Asked Questions
What cryptographic algorithms does ST33GTPMISPI support and at what key sizes?
The ST33GTPMISPI supports RSA-2048 and ECC-256 asymmetric cryptographic operations alongside SHA-256 hashing, all compliant with the TPM 2.0 specification. These algorithms cover the security requirements for secure boot, platform attestation, and encrypted key storage. The hardware accelerator handles these operations internally, offloading computation from the host processor at up to 33 MHz SPI clock.
Which industrial embedded platforms can integrate ST33GTPMISPI without additional level shifters?
The ST33GTPMISPI operates at a 3.3V supply and its SPI interface is directly compatible with industrial processors such as Intel Atom, NXP i.MX, and TI Sitara families running at 3.3V I/O. For 1.8V host interfaces, a simple level-shift stage is required. The device operates from -40°C to +85°C, covering the full industrial temperature range without derating.
How does ST33GTPMISPI compare to LPC-interface TPM modules for new PCB designs?
ST33GTPMISPI uses a 4-wire SPI bus, which requires fewer PCB signal traces than the 7-wire LPC bus used by traditional discrete TPM modules. The SPI version runs at up to 33 MHz, making it faster and more electrically compatible with modern embedded SoCs that have largely removed LPC support. This simplifies routing on compact industrial boards with limited pin counts.
