2. 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 µs per 64-byte block. In most cases, TCG key generation
operations will be completed using a proprietary mechanism in less than 1 msec.
