What are the key features of ST33TPM12LPCQFN?
- 32-bit ARM SecurCore SC300 CPU core provides hardware-enforced cryptographic operations and secure key storage compliant with TPM 1.2 specification
- LPC (Low Pin Count) interface enables direct integration with x86 and embedded platform chipsets without additional bridge circuitry
- Compact 32-pin VFQFPN 5x5x1.0 mm QFN package minimizes PCB footprint while supporting hardware root-of-trust for security-critical embedded designs
What is ST33TPM12LPCQFN used for?
The ST33TPM12LPCQFN is used in industrial PCs, embedded servers, and network appliances that require hardware-based root-of-trust and platform integrity measurement per TPM 1.2. Its LPC interface makes it a drop-in security chip for motherboards and embedded computing modules that already carry an LPC bus. It is also deployed in secure boot and disk encryption systems where cryptographic key isolation from the main CPU is mandatory.

Frequently Asked Questions
Which CPU core powers the ST33TPM12LPCQFN and what cryptographic operations does it accelerate in hardware?
The ST33TPM12LPCQFN is built on a 32-bit ARM SecurCore SC300 CPU with dedicated hardware accelerators for RSA up to 2048-bit, SHA-1, and AES-128 operations, enabling fast on-chip key generation and signing without burdening the host processor.
How does the LPC interface of this TPM simplify integration into x86 embedded motherboard designs?
The LPC (Low Pin Count) interface operates at 33 MHz with a 4-bit multiplexed bus, connecting directly to the LPC controller found on Intel and AMD platform chipsets. This means no SPI-to-LPC bridge or additional protocol conversion IC is required, reducing BOM cost and routing complexity.
What package does the ST33TPM12LPCQFN use and what board space does it require?
The device comes in a VFQFPN 32-pin QFN package measuring 5 mm × 5 mm × 1.0 mm, occupying just 25 mm² of PCB surface. The exposed thermal pad improves heat dissipation and the 0.5 mm lead pitch is compatible with standard 0402-adjacent SMT land patterns.
In which embedded security scenarios does ST33TPM12LPCQFN serve as a lower-complexity alternative to a discrete secure element?
When a platform already has an LPC bus — such as in ATX or Mini-ITX industrial motherboards — the ST33TPM12LPCQFN replaces a discrete secure element plus an interface bridge, saving at least 2 ICs and reducing secure-boot implementation time from weeks to days using standard TPM 1.2 software stacks.
