Description

The AT97SC3201 is a fully integrated security module designed to be integrated into

personal computers and other embedded systems. It implements version 1.1b of the

Trusted Computing Platform Alliance (TCPA) specification for Trusted Platform

Modules (TPM). This specification has been adopted by the Trusted Computing Group

(TCG).

The TPM includes a crypto accelerator capable of computing a 2048-bit RSA

signature in 500 ms and a 1024-bit RSA signature in 100 ms, both using CRT.

The chip communicates with the PC through the LPC interface, which runs at 33 MHz.

In addition, it supports SIRQ (for interrupts) and CLKRUN (to permit clock stopping).

The chip includes a full hardware random number generator that is used for the

TCG/TCPA protocol and is also available to the system for any random numbers it

may need during normal operation.
