Complete Security for PCs and Embedded Systems
The Atmel Trusted Platform Module (TPM) provides strong hardware-based public key (RSA) security for both personal computers and embedded processors on a single chip. It is a complete turnkey system that integrates industry-leading Atmel AVR® microcontroller architecture, Atmel EEPROM technology, and Atmel security technology. Implementing version 1.2 of the Trusted Computing Group (TCG) specification for TPMs, the chip delivers intellectual property protection, system integrity, authentication, and secure communications. The Trusted Platform Module Embedded TWI Development Kit received a 2008 Readers Tech Choice Award from eg3, an independent news source devoted to electronic design.
Key Features
- Turnkey solution — The TPM includes integrated, protected nonvolatile storage for cryptographic keys, secrets, and authorization information.
- Full TCG compliance — According to TCG, applications based on the trusted computing infrastructure exhibit superior security governance and risk management.
- Hardware security — The TPM includes a high-quality hardware random number generator, active shielding, and a variety of tamper-detection and response circuits.
- High performance — The TPM’s cryptographic accelerator can compute a 2048-bit RSA signature in 200ms.
- Energy savings — The TPM supports SIRQ for interrupts and CLKRUN to permit clock stopping for power savings in mobile computers.
- Software support — BIOS and hardware drivers are available for both Windows and Linux; third-party system and application software is also available.
- Two interfaces — There is a 33 MHz LPC interface for PC integration and a 2-wire interface for non-PC and embedded computing systems.

The Atmel Trusted Platform Module is a fully integrated security module designed to be integrated into computer systems and other embedded systems. The TPM conforms to TCG v1.2 specifications and includes a cryptographic accelerator capable of computing a 2048-bit RSA signature (key generation, signing, and verification) in 200ms. Performance of the SHA-1 accelerator is 20μs per 64-byte block. The AT97SC3204T version complies with the TWI I2C 2-wire protocol.
