Frequently Asked Questions
What cryptographic algorithms does the ST33TPM12SPIQFN support in hardware?
The ST33TPM12SPIQFN includes hardware accelerators for RSA-2048 and SHA-1 operations, enabling fast asymmetric key generation and digest computation without loading the host CPU. These accelerators make it suitable for high-throughput secure boot and attestation use cases requiring sub-millisecond cryptographic response times.
Which host interface does ST33TPM12SPIQFN use, and at what maximum clock speed?
The ST33TPM12SPIQFN communicates via an SPI interface, supporting clock frequencies up to 33 MHz, allowing fast data transfer between the TPM and the host processor. This makes it compatible with a wide range of microcontrollers and SoCs with standard SPI peripherals operating at 3.3 V logic levels.
For a compact embedded security design, how much board space does the ST33TPM12SPIQFN require?
The ST33TPM12SPIQFN comes in a 32-pin VFQFPN package measuring 5x5 mm with 1.0 mm height, occupying less than 25 mm² of PCB footprint. This compact form factor makes it ideal for space-constrained embedded systems such as industrial controllers, network appliances, and thin clients that require TPM 1.2 security without sacrificing board real estate.
