SLB9635TT12FW317NOXUMA1

Overview

The SLB9635TT12FW317NOXUMA1 is a Trusted Computing Group (TCG) 1.2 compliant embedded Trusted Platform Module designed for notebook and desktop architectures. It utilizes a 16-bit microcontroller based on the Infineon SLE66CXxxPE security controller family, fabricated in 0.22 µm CMOS technology. The device provides hardware-based cryptographic implementations including an Advanced Crypto Engine supporting RSA keys up to 2048 bits and a hardware accelerator for SHA-1 hash algorithms. It features a True Random Number Generator (TRNG), EEPROM for firmware and user data, and operates from a single 3.3 V power supply with a 33 MHz clock.

Feature Summary

• TCG 1.2 Compliant: Embedded software and hardware architecture fully adhere to TCG 1.2 standards.
• Cryptographic Capabilities: Includes an Advanced Crypto Engine (ACE) for RSA (up to 2048-bit keys) and a hardware-accelerated SHA-1 hash algorithm.
• Security Architecture: Based on the Infineon SLE66CXxxPE family, featuring tamper detection via tick counter, over/under voltage detection, and protection against dictionary attacks.
• Interface and Power: Connects via Low Pin Count (LPC) bus, operates at 33 MHz, supports dynamic clock shutdown (CLKRUN), and includes a power-saving sleep mode.

Applications

• Notebook and Desktop PC Security
• Microsoft Windows Vista and XP Integration
• Intel Trusted Execution Technology Support
