TPMs are specific microcontrollers that defend computing systems against unauthorised access and attacks. With extended temperature range versions, support for either serial or parallel device interfaces and ability to run either TPM 1.2 or 2.0, Infineon’s OPTIGA TPMs support current and anticipated future requirements for hardware-based trusted system applications across industrial, embedded, mobile or tablet and traditional computing environments.

The TPM was defined by the Trusted Computing Group (TCG) – a standardisation body including leading IT companies – which provides open standards intended to enable safe computing environments. Organisations use systems with built-in, trusted hardware and applications to better protect business-critical data (for example, using hard disc encryption), to manage secure authentication and stronger protection of user identities and to improve secure communication in connected computer networks.

Infineon’s TPM security chips successfully passed the most stringent security tests to prove the chip’s resistance against attacks. They have received TCG certification based on the international security standard “Common Criteria” and on TCG’s own compliance tests.

Each of the new TPM devices is based on an Infineon 16-bit security microcontroller and the company’s SOLID FLASH technology. They meet Microsoft Windows hardware certification requirements, are recommended by Google for Chrome OS systems and are supported in major open source operating systems.

The SLB96xx family is available with two package options, either TSSOP-28 or even smaller VQFN-32, which at 5 x 5 mm conserves valuable board space on mobile platforms. Two temperature ranges (-20 to 80C or -40 to 85C) provide flexibility for different application environments. The SLB9645 has the I2C interface commonly used in industrial, embedded and numerous mobile computing systems. Other new family members, the SLB9660 and SLB9665, use the LPC interface used in x86-based computing platforms.
