Frequently Asked Questions
Which TPM standard does the ST33TPM12SPIR28 implement and what CPU powers it?
The ST33TPM12SPIR28 is compliant with TPM 1.2, the widely adopted Trusted Computing Group standard for platform security. It is powered by a 32-bit ARM SecurCore SC300 CPU, which provides hardware-enforced isolation of cryptographic keys and platform integrity measurements from the host processor.
How does the SPI interface on the ST33TPM12SPIR28 simplify integration into embedded system designs?
The SPI interface requires only 4 signal lines—MOSI, MISO, SCK, and CS—allowing connection to virtually any embedded processor or system-on-chip with a standard SPI peripheral. This eliminates the need for LPC bus routing required by older TPM variants, reducing trace count and simplifying PCB layout in space-constrained boards.
For an industrial IoT gateway requiring secure key storage, what package and pin count does ST33TPM12SPIR28 offer?
It comes in a 28-pin TSSOP package measuring 9.7 mm x 4.4 mm, which fits on standard 0.65 mm pitch footprints. The 28 pins provide dedicated VCC, GND, SPI, and control lines while keeping the overall PCB area under 50 mm², making it practical for density-constrained industrial gateway boards.
