TPM Reference Design
Introduction
A Trusted Platform Module (TPM) is a crypto-processor that provides hardware-based protection to applications. This dedicated component includes various mechanisms to make software tamper-resistant, such as device authentication, cryptographic key generation and storage, integrity attestation, and more. For more information, see the Trusted Computing Group page.
Reference Design
The Mallow Carrier Board, designed as a volume solution for the Verdin family, features an OPTIGA™ TPM SLM 9670 chip, meeting the industrial requirements for security.
If you are creating a new carrier board design that includes a TPM chip, it is highly recommended that you use the Mallow Carrier Board schematics as a guide. The figure below shows the QSPI and SPI interfaces that you should use to connect a TPM chip to the carrier board.
If you are developing a carrier board that will include a TPM chip, using the Mallow Carrier Board schematics as a guide is highly recommended. This allows Toradex support to effectively assist you in case any issues arise during the development phase.
