*NOTICE: Stresses beyond those listed under "Absolute Maximum Ratings" may cause permanent damage to the device. This is a stress rating only and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of this specification may cause temporary or permanent failure. Exposure
to absolute maximum rating conditions for extended periods may affect device reliability.

The AT97SC3203 Trusted Platform Module (TPM) is the latest offering from Atmel,the world's leading choice for TPMs. Atmel, supplier of the world's first production v1.1b TPM, the AT97SC3201, expands its success into v1.2 TPMs with the AT97SC3203. Atmel continues to pace the development of TPM technology and actively participates in the Trusted Computing Group (TCG) and contributes expertise in the development of the TPM specifications. By utilizing Atmel TPMs, you can be confident that you are implementing the most advanced TPMs available on the market today and in the future.

The AT97SC3203 is a fully integrated security module designed to be integrated into personal computers and other embedded systems. It implements version 1.2 of the Trusted Computing Group specification for Trusted Platform Modules.

The AT97SC3203 includes a cryptographic accelerator capable of computing a 2048-bit RSA signature in 500 ms and a 1024-bit RSA signature in 100 ms. Performance of the SHA-1 accelerator is L50 s per 64-byte block. In most cases, TCG key generation operations will be completed using a proprietary mechanism in less than 1 msec.

The chip AT97SC3203 communicates with the PC through the LPC interface. The TPM supports SIRQ (for interrupts) and CLKRUN to permit clock stopping for power savings in mobile computers.
