Description

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 ([1][2][3]), and is also based on the TCG PC Client specific

TPM interface specifications 1.21 [5] and the PC Client implementation specification for

conventional BIOS [6] 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.

1.1

Hardware features

The ST33TPM12LPC is based on a smartcard-class secure MCU that incorporates the

most recent generation of ARM processors for embedded secure systems. Its SecurCore®

SC300™ 32-bit RISC core is built on the Cortex™ M3 core with additional security features

to help to protect against advanced forms of attacks.

Cadenced at 30 MHz, the SC300™ core brings great performance and excellent code

density thanks to the Thumb®-2 instruction set.

The ST33TPM12LPC offers an LPC (Low Pin Count) communication interface compatible

with Low Pin Count interface specification v1.1.

The ST33TPM12LPC features hardware accelerators for advanced cryptographic functions.

The EDES peripheral provides a secure DES (Data Encryption Standard) algorithm

implementation, while the NESCRYPT crypto-processor efficiently supports the public key

algorithm.

The ST33TPM12LPC operates in the 0 to +70°C temperature and 3.3V supply voltage

ranges.

In order to meet environmental requirements, ST offers these devices in different grades of

ECOPACK® packages, depending on their level of environmental compliance. ECOPACK®
