2. Block Diagram
The TPM includes hardware Random Number Generator (RNG), including a FIPS certified 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 1.3, also available on the TCG web
site. Implementation guidance for PC platforms is outlined in the TCG PC Client Specific Implementation
Specification for Conventional Bios, version 1.2, also available on the TCG web site.
