Atmel AT97SC3204 Trusted Platform Module LPC Interface SUMMARY DATASHEET Features Fully compliant to the Trusted Computing Group (TCG) Trusted Platform Module (TPM) version 1.2 specification Compliant with TCG PC client-specific TPM Interface Specification (TIS) version 1.2 Single-chip, turnkey solution Hardware asymmetric crypto engine Atmel® AVR® RISC microprocessor Internal EEPROM storage for RSA keys 33MHz Low Pin Count (LPC) bus for easy PC interface Secure hardware and firmware design and chip layout Internal, high-quality Random Number Generator (RNG) – FIPS 140-2 compliant NV storage space for 1756 bytes of user defined data 3.3V supply voltage 28-lead thin TSSOP, 28-lead wide TSSOP, or 40-pad QFN packages Offered in both commercial (0 to 70°C) and industrial (-40 to +85°C) temperature ranges 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. The complete document is available under NDA.

Atmel AT97SC3204 LPC Interface [SUMMARY DATASHEET] Atmel-5295ES-TPM-AT97SC3204-LPC-Interface-Datasheet-Summary-032013 2 2. Block Diagram GPIO-Express-00 ROM Program EEPROM Program 33MHz LPC Interface AVR 8-bit RISC CPU SRAM EEPROM Data GPIO RNG CRYPTO Engine Timer Physical Security 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.
