Overview

The SLB 9670 is a high-performance Trusted Platform Module (TPM) designed for PC, server, and embedded systems requiring hardware-based security. It fully complies with the TCG TPM 2.0 standard and utilizes a high-speed SPI interface for seamless integration with modern microprocessors and chipsets. This module provides a robust foundation for secure boot, platform integrity, and cryptographic key management.

Why Choose This Part

The SPI interface allows for simplified PCB routing and lower pin counts compared to older LPC-based TPMs. It features a low sleep current of 110uA and operates within a standard 3V to 3.6V range, making it suitable for energy-conscious embedded designs. Its TCG 2.0 compliance ensures broad compatibility with standard security software stacks.

Applications

Secure Boot
Verification of firmware and OS integrity during the system power-up sequence.
Network Equipment
Providing identity and secure key storage for industrial gateways, routers, and switches.
Cloud Edge Computing
Hardware-rooted security for edge nodes to ensure trusted data transmission to cloud services.

Getting Started

To integrate this part, verify that your host CPU or SoC BIOS/UEFI supports the TCG SPI protocol. Engineers typically use the TPM Software Stack (TSS) on Linux or the Windows TPM management console for application development. Evaluation can be performed using Infineon-compatible TPM 2.0 add-on boards for Raspberry Pi or industrial PC platforms.
