SLB9635TT12FW319XUMA1

Overview

The SLB9635TT12FW319XUMA1 is a Trusted Computing Group (TCG) 1.2 compliant embedded Trusted Platform Module (TPM). It utilizes Infineon’s 16-bit security controller architecture implemented in 0.22 µm CMOS technology. The device integrates an Advanced Crypto Engine supporting RSA keys up to 2048 bits, a hardware accelerator for SHA-1 hashing, and a True Random Number Generator (TRNG). It operates on a single 3.3 V power supply within a temperature range of 0°C to +70°C. Communication with the host system is facilitated via a Low Pin Count (LPC) interface running at a 33 MHz clock frequency.

Procurement Notes

Verify component authenticity through authorized distribution channels. Confirm that the specific ordering suffix matches the required package and tape/reel specifications. Ensure compatibility with existing motherboard LPC headers and BIOS implementations before procurement.

Selection Notes

Select this component for platforms requiring TCG 1.2 certification and EAL 4 Medium security rating. It is suitable for designs needing integrated RSA 2048-bit capabilities and TPM 1.2 firmware without external cryptographic co-processors. Verify voltage levels match the 3.3 V requirement.

Part Context

This part belongs to the Infineon SLB9635 TT 1.2 series of security controllers. It is based on the SLE66CXxxPE security controller family and provides a complete hardware and software stack for trusted computing platforms, including support for Endorsement Keys and EK certificates.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Evaluate other TCG 1.2 compliant TPMs from Infineon or third-party vendors only if they match the LPC interface, pinout, and voltage requirements.
