2. Description
The Atmel
®
AT97SC3204 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 (TCG) specification for Trusted Platform
Modules (TPM).
The TPM includes a cryptographic accelerator capable of computing a 2048-bit RSA
signature in 200ms and a 1024-bit RSA signature in 40ms. Performance of the SHA-1
accelerator is 20µs per 64-byte block.
The chip 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.
