Overview

The ST33KTPM2X32DKG9 is a Trusted Platform Module (TPM) based on the ARM SecurCore SC300 processor, designed to provide a hardware-based root of trust for embedded systems. It supports both SPI and I2C interfaces for flexible integration into various host architectures. This security controller operates over a wide temperature range from -40degC up to 105degC, making it suitable for both industrial and commercial environments.

Why Choose This Part

The ST33KTPM2X32DKG9 utilizes the proven ARM SecurCore SC300 architecture, offering high-level security features within a compact 32-UFQFPN package. Its dual-interface support (SPI and I2C) and wide 1.8V to 3.3V supply voltage range simplify integration into existing low-power or high-performance system designs.

Applications

Secure Boot Hardware Root of Trust
Ensures that only authorized firmware is executed by the host processor during the boot sequence.
Cryptographic Key Management
Provides secure storage and generation of cryptographic keys, protecting them from physical and software-based extraction.
Device Identity and Authentication
Facilitates secure platform identity to enable remote attestation and trusted communication with cloud services.
Industrial Gateway Security
Protects sensitive configuration data and communication logs in industrial IoT gateways and controllers.

Getting Started

Engineers can integrate the ST33KTPM2X32DKG9 using standard TPM software stacks such as TCG Software Stack (TSS) 2.0. To begin development, verify the host processor's SPI or I2C master driver compatibility with the ST33K series and consult STMicroelectronics for the specific firmware version (0x00.09.01.01) documentation.

Also Consider

ATSHA204A MCHPMicrochip Technology - A lower-cost secure element alternative if full TPM specification compliance is not required for the application.
