Infineon – OPTIGA™ TPM: Certified Security Solutions for Trusted Computing in PC and Embedded Applications

Infineon Logo
The Infineon OPTIGA™ TPM (Trusted Platform Module) family is a standardized security controller family which provides a wide range of security functions for embedded platforms. As the leader of Trusted Computing solutions, Infineon offers a broad range of products meeting your specific requirements.

Security and Functionality
All OPTIGA™ TPM products are based on Infineon’s advanced hardware security technology. The products are designed according to the Trusted Computing Group (TCG) specifications and are Common Criteria certified1 to EAL4+. The security functions include system and data integrity, authentication, secured communication, secured data storage and secured updates.

Performance and Power

Implemented on a 16-bit state-of-the-art security controller from Infineon, the products meet the latest Microsoft Windows boot time and performance criteria. Furthermore the products are supported in Linux OS and derivates.

A sleep current of down to 110μA allows smooth integration into a broad range of devices requiring power efficient battery operated designs.

Extended Temperature Range and Packages

The OPTIGA™ TPM family supports an improved commercial temperature range as standard (-20°C to +85°C) as well as an extended temperature range (-40°C to +85°C) for industrial applications. The OPTIGA™ TPM is available in TSSOP-28 package or the small VQFN-32 package (5 x 5mm2), which saves precious board space on your mobile platforms.

Migrate to TCG TPM 2.0 Today

Leading the way into the future, Infineon is the first provider offering a TPM 2.0 product according to the latest specification. With this early expertise we support your smooth transition to the new standard.

Fully Certified and State-of-The-Art Security
For new products of the Infineon OPTIGA™ TPM family, the Common Criteria certification is a key focus. As the first and still leading the list, Infineon had its TPMs listed on the official TCG product list showing that the TCG TPM standard is fulfilled.

Infineon is a driver in the Trusted Computing Group (TCG), the standardization organization formed to develop open, vendor-neutral, global industry standards for hardware security. With an Infineon
representative serving as the TCG president and a strong presence and chairs in various working groups, Infineon is working on future security standards and driving innovation.

This family builds a root of trust in PC, mobile and embedded solutions based on the Trusted Computing Group specifications.
