OPTIGA™ TPM SLI9670 A-TPM

Overview

Add OPTIGA™ TPM to AURIX™ MCU-based systems to take security to the highest level

The OPTIGA™ TPM SLI 9670 A-TPM board allows developers to quickly and easily evaluate and develop AURIX™ 2nd generation MCU-based systems offering enhanced levels of security. It is an add-on board for the Infineon AURIX™ TC3xx, supported by the TPM Software Stack (TSS).

The header of the A-TPM board is designed to be connected to the AURIX™ TriBoard TC389 with the TC389QP microcontroller, communicating via SPI.

OPTIGA™ TPM is a standardized cryptographic processing device with enhanced security features such as tamper-resistant key storage, cryptography (ECC, RSA, AES, SHA-1/2) and key management, which combine to make it a hardware trust anchor. For fast time-to-market, OPTIGA™ TPM comes as a pre-programmed, turnkey solution with highly configurable functionality integrated through TSS 2.0, which acts as an AUTOSAR-compatible complex driver. The software stack can run on various host processors or host operating systems.

An application note is available to support AURIX™ TC3xx-based host MCU deployments. It includes:

  • Documentation of HW/SW setup
  • TSS 2.0 for AURIX™ 2nd generation TC3xx
  • Example source code and tutorials for typical applications spanning data decryption, data/certificate storage, signing of data and secured communication sessions
