Features
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.
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.

The chip includes a full hardware random number generator that is used for the TCG
protocol and is also available to the system for any random numbers it may need
during normal operation.
