Infineon expands security controller portfolio for USB tokens.

Security Controllers for USB Tokens Offer Versatility

July 10, 2025
Infineon's security controller portfolio for USB tokens includes ID Key S USB for more security and versatility.

Infineon Technologies is expanding its portfolio for Universal Serial Bus (USB) tokens, dongles, security keys, and other hardware authenticators with the Infineon ID Key family. Designed for a wide range of USB- and USB/NFC-token devices and applications, the highly secure and versatile devices leverage the company's SLC38 security controller and a USB bridge controller in one single package.

The controllers offer flexibility and simplify complex application deployments while reducing the bill of materials and related costs, as well as providing the highest security levels. The portfolio supports a range of use cases, including certificate-based authentication and Fast Identity Online (FIDO) authentication with device-bound passkeys, digital signatures, encryption, access control, software protection, and cryptocurrency.

Features include a 32-bit CPU clocked at 100 MHz and 24 kB of RAM for fast and secure execution of applications while delivering high operating-system performance for a wide range of use cases. Non-volatile memory sizes of up to 800 kB are available for data, cryptographic keys, and software for multiple applications.

The ID Key S USB is certified to CC EAL 6+ (high) and complies with FIPS 140-3 hardware requirements, allowing products to apply for FIPS 140-3 certification. It has a footprint of 4 × 4 × 0.85 mm, making it easy to integrate into space-critical token devices.
