TPM 2.0 security chip provides comprehensive protection for consumer devices

The STMicroelectronics ST33KTPM2X trusted platform module protects against a wide range of threats to the security of consumer computing devices. Independent validation allows for compliance with security regulations.

STMicroelectronics has extended the STSAFE-TPM family with the introduction of the ST33KTPM2X trusted platform module (TPM) for use in consumer devices such as PCs, workstations and servers.

The ST33KTPM2X TPM offers improved performance, enhanced security, and increased memory capacity, giving manufacturers of consumer devices the capability to adapt to the growing severity of security challenges to connected products. The TPM is suitable for security functions including:

Platform trusted identity
Device health attestation
Anti-counterfeiting
Protection of keys and critical data
Cryptography
TLS secure channel communication
Self-recovery

The TPM has independently verified security status according to Common Criteria EAL4+, Trusted Computing Group (TCG), and the US government Federal Information Processing Standard (FIPS) 140-3 specifications. This provides manufacturers with a high level of confidence in the security protection provided by the chip, and helps them to meet the requirements of security regulations.

For integration into product designs, the ST33KTPM2X is compatible with the Windows and Linux® operating systems, and the TCG TPM software stack. It supports firmware upgrades for the addition of new standard features and cryptography capabilities.

Evaluation Board

Part Number: STPM4RasPIV21

The STPM4RasPIV21 is an extension board for connecting the ST33KTPM trusted platform module (TPM) security chips to Raspberry Pi boards, or to an STM32 microprocessor development kit such as the STM32MP157F-DK2 or STM32MP135F-DK.

The board is for product evaluation, use case development and design integration. The STPM4RasPIV21 is shipped with one trusted platform module soldered to the board.

Features:

26-pin female connector to plug on Raspberry Pi or STM32MPx-DK boards
I2C or SPI configurable interface
Reset button to reset the TPM device without a platform restart
26-pin male connector to ease probing and to plug to the same or another extension board
