Frequently Asked Questions
Which TPM specification does ST33TPM12LPCR28 implement and what CPU powers it?
ST33TPM12LPCR28 implements the TPM 1.2 specification as defined by the Trusted Computing Group (TCG). It is powered by a 32-bit ARM SecurCore SC300 CPU, which provides a dedicated secure processing environment for cryptographic operations, platform integrity measurements, and key storage independent of the host system's main processor.
How does the LPC interface on ST33TPM12LPCR28 connect to a host motherboard?
The LPC (Low Pin Count) interface connects ST33TPM12LPCR28 directly to the LPC bus on the host motherboard chipset using just 4 data lines plus clock and control signals. This minimizes PCB routing complexity and is the standard interface for TPM chips on x86 motherboards, requiring no dedicated bridge IC between the 28-pin TSSOP TPM and the southbridge.
What cryptographic algorithms does ST33TPM12LPCR28 support for platform security?
ST33TPM12LPCR28 supports RSA 2048-bit key generation and digital signatures plus SHA-1 hashing as mandated by the TPM 1.2 specification. The hardware-based cryptographic engine handles these operations within the secure SC300 core, ensuring private keys never leave the TSSOP-28 chip, which is essential for secure boot, BitLocker disk encryption, and platform attestation workflows.
In what form factor and dimensions does ST33TPM12LPCR28 ship for PCB integration?
ST33TPM12LPCR28 is available in a TSSOP-28 package with body dimensions of 9.7 mm x 4.4 mm. The 28-pin small outline package with standard 0.65 mm pitch leads is compatible with automated SMT assembly. This compact form factor allows the TPM 1.2 chip to fit within the small reserved area on standard ATX and mini-ITX motherboard layouts.
