Description The AT97SC3203S is a fully integrated security module designed to be integrated into embedded systems. It implements version 1.2 of the Trusted Computing Group (TCG) specification for Trusted Platform Modules (TPM). The TPM 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 50 s per 64-byte block. In most cases, TCG key generation operations will be completed using a proprietary mechanism in less than 1 msec. 5132BS-TPM-1/08 Note: This is a summary document. A complete document is available under NDA. For more information, please contact your local Atmel sales office. Figure 2-1.

Description (continued) Communication to and from the TPM occurs through a modified 100-kHz SMBus two-wire interface. The TPM includes a hardware random number generator, including a FIPS-approved Pseudo Random Number Generator, that is used for key generation and TCG protocol functions. The RNG is also available to the system to generate random numbers that may be needed during normal operation. The chip uses a dynamic internal memory management scheme to store multiple RSA keys. Other than the standard TCG commands (TPM_FlushSpecific, TPM_Loadkey2), no system intervention is required to manage this internal key cache. Full documentation for TCG primitives can be found on the TCG Web site located at www.trustedcomputinggroup.org. This specification includes only mechanical, electrical and SMBus protocol information. 3 5132BS-TPM-1/08 3. Ordering Information Table 3-1.
