SLB9635TT12FW319XUMA2

Overview

The SLB9635TT12FW319XUMA2 is a Trusted Computing Group (TCG) 1.2 compliant embedded security controller designed for notebook and desktop architectures. It utilizes Infineon’s 16-bit microcontroller architecture in 0.22 µm CMOS technology, featuring an Advanced Crypto Engine supporting RSA up to 2048 bits and a hardware accelerator for SHA-1. The device includes a True Random Number Generator (TRNG), EEPROM for firmware and user data, and a tick counter with tamper detection. Operating at 3.3 V with a 33 MHz clock, it connects via the Low Pin Count (LPC) interface and is housed in a 28-pin TSSOP package.

Feature Summary

• TCG 1.2 Compliant: Embedded software and hardware architecture fully adhere to Trusted Computing Group specifications.
• Cryptographic Capabilities: Features an Advanced Crypto Engine for RSA 2048-bit keys and a dedicated hardware accelerator for SHA-1 hashing.
• Security Architecture: Includes a True Random Number Generator (TRNG), memory encryption (MED), and protection against dictionary attacks.
• Interface & Power: Connects via LPC bus operating from a single 33 MHz clock; supports power-down signals for low-power standby modes.

Applications

• Notebook and Desktop PC Security
• Intel Trusted Execution Technology Integration
• AMD Secure Virtual Machine Architecture Support

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm that the specific ordering suffix matches the required firmware version and packaging configuration. Ensure compliance with local import regulations regarding cryptographic components. Check for end-of-life status or alternative sourcing requirements if production continuity is critical.

Selection Notes

Select this component for systems requiring TCG 1.2 certification and LPC interface compatibility. Ensure the host platform supports the 3.3 V supply voltage and 33 MHz clock speed. Verify that the application requires the specific 16-bit controller architecture and RSA 2048-bit capabilities provided by this security solution.

Part Context

This part belongs to the Infineon OPTIGA TPM family, specifically targeting legacy TCG 1.2 standards for computing platforms. It serves as a hardware root of trust for personal computers, differentiating itself from newer TPM 2.0 solutions by focusing on established Windows and BIOS integration protocols defined in the 1.2 specification.

Replacement Considerations

Direct replacements must maintain TCG 1.2 compliance and LPC interface support. Verify pinout compatibility with the 28-TSSOP package. Consider firmware version alignment if migrating between similar Infineon security controllers within the SLE66CXxxPE family.
