Description
The Atmel AT97SC3204 is a fully integrated security module designed to be integrated
into personal computers and other embedded systems. It implements version 1.2 of the
Trusted Computing Group (TCG) specification for Trusted Platform Modules (TPM).
The TPM includes a cryptographic accelerator capable of computing a 2048-bit RSA
signature in 200ms and a 1024-bit RSA signature in 40ms. Performance of the SHA-1
accelerator is 20μs per 64-byte block.
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.
This is a summary document.

Circuitry
The TPM includes a hardware random number generator, including a FIPS-approved Pseudo Random Number
Generator that is used for key generation and TCG protocol functions. The RNG is also available to the system to
generate random numbers that may be needed during normal operation.
The chip uses a dynamic internal memory management scheme to store multiple RSA keys. Other than the standard
TCG commands (TPM_FlushSpecific, TPM_Loadkey2), no system intervention is required to manage this internal key
cache.
The TPM is offered to OEM and ODM manufacturers as a turnkey solution, including the firmware integrated on the chip.
In addition, Atmel provides the necessary device driver software for integration into certain operating systems, along with
BIOS drivers. Atmel will also provide manufacturing support software for use by OEMs and ODMs during initialization
and verification of the TPM during board assembly.
Full documentation for TCG primitives can be found in the TCG TPM Main Specification, Parts 1 to 3, on the TCG Web
site located at https://www.trustedcomputinggroup.org. TPM features specific to PC Client platforms are specified in the
“TCG PC Client Specific TPM Interface Specification, Version 1.2”, also available on the TCG web site. Implementation
guidance for 32-bit PC platforms is outlined in the “TCG PC Client Specific Implementation Specification for Conventional
BIOS for TCG Version 1.2”, also available on the TCG website.

tolerances, datums, etc.
2. Dimension b applies to metallized terminal and is measured between 0.15 mm and 0.30 mm from the terminal tip. If the
terminal has the optional radius on the other end of the terminal, the dimension should not be measured in that radius area.
