Module

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).

AT97SC3201

Summary

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.

Communication to and from the TPM can occur through one of two interface

protocols: either a 33-MHz LPC interface or a 100-KHz SMBus two-wire interface.
