STMicroelectronics has announced PSA Certified Level-3 and SESIP[1]3 certifications for its general-purpose secure STM32U585* microcontroller, passing tests for logical, board, and basic physical resistance that confirm a substantial level of cyber protection.
With enhanced tamper resistance and software protection, the STM32U585 is also suitable for controlling PIN Transaction Security (PTS) equipment that must satisfy Payment Card Industry Security Standards Council (PCI SSC) requirements. As a secure, general-purpose microcontroller, the STM32U585 offers an all-in-one solution that simplifies the design and production of Point-Of-Sale (POS) and self-service payment terminals.
Typically, achieving recognition as an official PTS Approved Device requires a dedicated security chip to resist online and side-channel attacks, with a separate microcontroller (MCU) to manage features such as the keyboard, display, and USB connection. The STM32U585 can now consolidate all these capabilities, enabling a simplified design and streamlining production logistics from purchasing and inventory management to final assembly. Terminal makers can also test and certify their products to applicable standards such as PCI PTS v6 more quickly and easily.
The STM32U585 is compliant with Arm® Trusted Base System Architecture (TBSA) requirements and features Arm TrustZone® architecture. Numerous typical security features for connected devices are included, including cryptographic accelerators, secure data storage, secure firmware installation, secure boot, and secure firmware update.
