IFXOPTIGA TPM SLM 9670
Overview
The SLM9670AQ20FW1311XTMA1 is a 16-bit Trusted Platform Module (TPM) designed specifically for industrial and IoT applications requiring high levels of hardware-based security. Compliant with TCG TPM 2.0 standards, it features a tamper-resistant secure microcontroller with physical and logical attack protections. It operates over an extended industrial temperature range of -40 to 105 degrees Celsius with an SPI interface for easy integration into modern host systems.
Why Choose This Part
This module offers a dedicated hardware RNG and support for RSA-2048, ECC NIST P256, and SHA-256 algorithms. Its industrial qualification (JEDEC JESD-47) and hardened flash memory ensure reliable operation in harsh environments where standard consumer TPMs might fail. The device includes internal memory encryption and sensors to detect physical tampering or side-channel attacks.
Applications
Key Specifications
Getting Started
Integration requires a host microcontroller or microprocessor with an SPI master interface and a TPM 2.0 software stack, such as WolfTPM or the Linux TPM TDDL driver. Engineers should verify voltage rail compatibility for either 1.8V or 3.3V operation as specified in the PG-VQFN-32-13 pinout. Infineon provides the OPTIGA TPM Explorer and evaluation kits to speed up the initial firmware development and command set testing.
