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. Communication to and
from the TPM occur through a 33-MHz LPC interface.

... Figure 2. AT97SC3201 Block Diagram IOA IOB IOC 32.768 kHz 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. A real-time clock function is available using an external battery and crystal. The chip provides tamper detection if the battery or crystal are removed or tampered with, and the current time value can be signed by the appropriate internal keys to verify its accuracy ...
