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.
