Complete Security for PCs and Embedded Systems


The FIPS 140-2 Certified Trusted Platform Module (TPM) provides strong hardware-based public key (RSA) security for both personal computers and embedded processors on a single chip. It is a complete turnkey system that integrates our industry-leading AVR® microcontroller architecture, EEPROM technology and security technology. Implementing version 1.2 of the Trusted Computing Group (TCG) specification for TPMs, the chip supports secure boot via platform integrity measurements, intellectual property protection, authentication, and secure communications. The AT97SCx series is offered in three different interfaces: SPI, LPC, and I2C. Versions are available to support commercial and industrial temperature ranges.

Product Highlights


  • Turnkey solution: The TPM includes integrated, protected nonvolatile storage for cryptographic keys, secrets, and authorization information
  • Full TCG compliance: According to TCG, applications based on the Trusted Computing infrastructure exhibit superior security governance and risk management
  • Hardware security: The TPM includes a high-quality hardware random number generator, active shielding, and a variety of tamper-detection and response circuits
  • High performance: The TPM’s cryptographic accelerator can compute a 2048-bit RSA signature in 200 ms
  • Energy savings: The TPM supports SIRQ for interrupts and CLKRUN to permit clock stopping for power savings in mobile computers
  • Software support: BIOS and hardware drivers are available for both Windows® and Linux® operating systems; third-party system and application software is also available
  • Two interfaces: The TPM offers a 33 MHz LPC interface for PC integration and a 2-wire interface for non-PC and embedded computing systems.
