ST33TPM12LPCTrusted Platform Module with LPC interface based on 32-bit ARM SecurCore SC300 CPU
The ST33TPM12LPC is a cost-effective and high performance Trusted Platform Module (TPM) targeting embedded system applications.
This device implements the functions defined by the Trusted Computing Group (www.trustedcomputinggroup.org) in the TCG Trusted Platform Module Specifications version 1.2 Level 2 Revision 116 (), and is also based on the TCG PC Client specific TPM interface specifications 1.21  and the PC Client implementation specification for conventional BIOS  for what concerns the TPM internal register list and bit definitions.
The ST33TPM12LPC is based on a secure MCU hardware platform.
The ST33TPM12LPC is built on a 32-bit ARM® reduced instruction set computing (RISC) processor which provides high cryptographic and general performances. A crypto-processor NESCRYPT is also present to support efficiently all public key cryptographic algorithms.
