Overview

The SLB9672XU20FW1624XTMA1 is a high-performance Trusted Platform Module (TPM 2.0) from Infineon's OPTIGA family, designed specifically for securing embedded systems and IoT devices. It features a standardized SPI interface and includes a Post-Quantum Cryptography (PQC) protected firmware update mechanism to ensure long-term security against evolving threats.

Why Choose This Part

This TPM offers a compact 32-pin PG-UQFN package with a small 3.6mm x 3.6mm footprint, making it ideal for space-constrained designs. It operates across a wide voltage range of 1.65V to 3.6V and includes a low-power sleep mode drawing only 120uA, suitable for energy-efficient embedded applications.

Applications

Industrial IoT Gateways
Provides a hardware-based root of trust for securing industrial data transmissions and protecting device identity.
Edge Computing Servers
Secures boot processes and manages cryptographic keys for decentralized computing infrastructure.
Network Infrastructure
Authenticates routers, switches, and access points to prevent unauthorized network access.
Critical Infrastructure Control
Ensures firmware integrity in PLC and SCADA systems through hardware-verified secure boot.

Getting Started

Integration begins by connecting the SPI interface to the host microcontroller or processor and utilizing the Infineon OPTIGA TPM Linux or microcontroller-based software libraries. Engineering teams should verify the hardware connection to the 3.6mm UQFN package and ensure the 1.65V to 3.6V power rails are stable for the 35mA peak run current.

Also Consider
