Description
The AT97SC3203 Trusted Platform Module (TPM) is the latest offering from Atmel,
the world's leading choice for TPMs. Atmel, supplier of the world's first production
v1.1b TPM, the AT97SC3201, expands its success into v1.2 TPMs with the
AT97SC3203. Atmel continues to pace the development of TPM technology and
actively participates in the Trusted Computing Group (TCG) and contributes expertise
in the development of the TPM specifications. By utilizing Atmel TPMs, you can be
confident that you are implementing the most advanced TPMs available on the market
today and in the future.
The AT97SC3203 is a fully integrated security module designed to be integrated into
personal computers and other embedded systems. It iwmwwp.DaletaSmheeet4nU.ctosm version 1.2 of the
Trusted Computing Group specification for Trusted Platform Modules.
The TPM includes a cryptographic accelerator capable of computing a 2048-bit RSA
signature in 500 ms and a 1024-bit RSA signature in 100 ms. Performance of the
SHA-1 accelerator is L50 µs per 64-byte block. In most cases, TCG key generation
operations will be completed using a proprietary mechanism in less than 1 msec.
The chip communicates with the PC through the LPC interface. The TPM supports
SIRQ (for interrupts) and CLKRUN to permit clock stopping for power savings in
mobile computers.
