Overview

The SLB9672AU20FW1624XTMA1 is a high-performance Trusted Platform Module (TPM 2.0) designed to provide a hardware-based root of trust for embedded and IoT systems. It features an I2C interface for host communication and includes a post-quantum cryptography (PQC) protected firmware update mechanism to ensure long-term security resilience.

Why Choose This Part

This module is compliant with TCG TPM Library specification v1.59 and features FIPS 140-2 Level 2 certification. It offers a compact 32-pin UQFN package and maintains low power consumption with a sleep current of only 120uA, making it suitable for power-constrained deployments.

Applications

Industrial IoT Gateways
Provides secure boot, device identity, and encrypted storage for edge computing hardware.
Network Infrastructure
Secures routers and switches against firmware tampering and unauthorized configuration changes.
Secure Cloud Provisioning
Uses pre-provisioned Endorsement Keys (EK) to simplify zero-touch onboarding to cloud platforms.
Platform Integrity
Utilizes 24 Platform Configuration Registers (PCRs) to monitor and verify the system boot state.

Getting Started

Integration requires an I2C-capable host microcontroller or SoC and a TPM software stack such as TSS 2.0. Engineers can evaluate the platform using Infineon's OPTIGA TPM evaluation boards or the Raspberry Pi TPM adapter boards for rapid prototyping.

Also Consider

ATSHA204A MCHPMicrochip Technology - A more cost-effective, simpler secure element for basic authentication and symmetric key storage if full TPM 2.0 compliance is not required.
